Recent PostgreSQL Security Vulnerabilities

A flaw was found in PostgreSQL

CVE-2022-1552 8.8 - High - August 31, 2022

A flaw was found in PostgreSQL. There is an issue with incomplete efforts to operate safely when a privileged user is maintaining another user's objects. The Autovacuum, REINDEX, CREATE INDEX, REFRESH MATERIALIZED VIEW, CLUSTER, and pg_amcheck commands activated relevant protections too late or not at all during the process. This flaw allows an attacker with permission to create non-temporary objects in at least one schema to execute arbitrary SQL functions under a superuser identity.

SQL Injection

Odyssey passes to server unencrypted bytes

CVE-2021-43766 8.1 - High - August 25, 2022

Odyssey passes to server unencrypted bytes from man-in-the-middle When Odyssey is configured to use certificate Common Name for client authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption. This is similar to CVE-2021-23214 for PostgreSQL.

Improper Certificate Validation

Odyssey passes to client unencrypted bytes

CVE-2021-43767 5.9 - Medium - August 25, 2022

Odyssey passes to client unencrypted bytes from man-in-the-middle When Odyssey storage is configured to use the PostgreSQL server using 'trust' authentication with a 'clientcert' requirement or to use 'cert' authentication, a man-in-the-middle attacker can inject false responses to the client's first few queries. Despite the use of SSL certificate verification and encryption, Odyssey will pass these results to client as if they originated from valid server. This is similar to CVE-2021-23222 for PostgreSQL.

Improper Certificate Validation

A vulnerability was found in PostgreSQL

CVE-2022-2625 8 - High - August 18, 2022

A vulnerability was found in PostgreSQL. This attack requires permission to create non-temporary objects in at least one schema, the ability to lure or wait for an administrator to create or update an affected extension in that schema, and the ability to lure or wait for a victim to use the object targeted in CREATE OR REPLACE or CREATE IF NOT EXISTS. Given all three prerequisites, this flaw allows an attacker to run arbitrary code as the victim role, which may be a superuser.

Improper Control of Dynamically-Managed Code Resources

PostgreSQL JDBC Driver (PgJDBC for short)

CVE-2022-31197 8 - High - August 03, 2022

PostgreSQL JDBC Driver (PgJDBC for short) allows Java programs to connect to a PostgreSQL database using standard, database independent Java code. The PGJDBC implementation of the `java.sql.ResultRow.refreshRow()` method is not performing escaping of column names so a malicious column name that contains a statement terminator, e.g. `;`, could lead to SQL injection. This could lead to executing additional SQL commands as the application's JDBC user. User applications that do not invoke the `ResultSet.refreshRow()` method are not impacted. User application that do invoke that method are impacted if the underlying database that they are querying via their JDBC application may be under the control of an attacker. The attack requires the attacker to trick the user into executing SQL against a table name who's column names would contain the malicious SQL and subsequently invoke the `refreshRow()` method on the ResultSet. Note that the application's JDBC user and the schema owner need not be the same. A JDBC application that executes as a privileged user querying database schemas owned by potentially malicious less-privileged users would be vulnerable. In that situation it may be possible for the malicious user to craft a schema that causes the application to execute commands as the privileged user. Patched versions will be released as `42.2.26` and `42.4.1`. Users are advised to upgrade. There are no known workarounds for this issue.

SQL Injection

A malicious, but authorised and authenticated user can construct an HTTP request using their existing CSRF token and session cookie to manually upload files to any location

CVE-2022-0959 6.5 - Medium - March 16, 2022

A malicious, but authorised and authenticated user can construct an HTTP request using their existing CSRF token and session cookie to manually upload files to any location that the operating system user account under which pgAdmin is running has permission to write.

Unrestricted File Upload

** DISPUTED ** In pgjdbc before 42.3.3, an attacker (who controls the jdbc URL or properties)

CVE-2022-26520 9.8 - Critical - March 10, 2022

** DISPUTED ** In pgjdbc before 42.3.3, an attacker (who controls the jdbc URL or properties) can call java.util.logging.FileHandler to write to arbitrary files through the loggerFile and loggerLevel connection properties. An example situation is that an attacker could create an executable JSP file under a Tomcat web root. NOTE: the vendor's position is that there is no pgjdbc vulnerability; instead, it is a vulnerability for any application to use the pgjdbc driver with untrusted connection properties.

When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker

CVE-2021-23214 8.1 - High - March 04, 2022

When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption.

SQL Injection

A man-in-the-middle attacker

CVE-2021-23222 5.9 - Medium - March 02, 2022

A man-in-the-middle attacker can inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption.

Insufficiently Protected Credentials

A flaw was found in postgresql

CVE-2021-3677 6.5 - Medium - March 02, 2022

A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting.

pgjdbc is the offical PostgreSQL JDBC Driver

CVE-2022-21724 9.8 - Critical - February 02, 2022

pgjdbc is the offical PostgreSQL JDBC Driver. A security hole was found in the jdbc driver for postgresql database while doing security research. The system using the postgresql library will be attacked when attacker control the jdbc url or properties. pgjdbc instantiates plugin instances based on class names provided via `authenticationPluginClassName`, `sslhostnameverifier`, `socketFactory`, `sslfactory`, `sslpasswordcallback` connection properties. However, the driver did not verify if the class implements the expected interface before instantiating the class. This can lead to code execution loaded via arbitrary classes. Users using plugins are advised to upgrade. There are no known workarounds for this issue.

Improper Initialization

A flaw was found in postgresql

CVE-2021-32028 6.5 - Medium - October 11, 2021

A flaw was found in postgresql. Using an INSERT ... ON CONFLICT ... DO UPDATE command on a purpose-crafted table, an authenticated database user could read arbitrary bytes of server memory. The highest threat from this vulnerability is to data confidentiality.

A flaw was found in postgresql

CVE-2021-32029 6.5 - Medium - October 08, 2021

A flaw was found in postgresql. Using an UPDATE ... RETURNING command on a purpose-crafted table, an authenticated database user could read arbitrary bytes of server memory. The highest threat from this vulnerability is to data confidentiality.

Out-of-bounds Read

A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before 9.6.22

CVE-2021-32027 8.8 - High - June 01, 2021

A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before 9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Buffer Overflow

An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11

CVE-2021-3393 4.3 - Medium - April 01, 2021

An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read.

Generation of Error Message Containing Sensitive Information

A flaw was found in PostgreSQL in versions before 13.2

CVE-2021-20229 4.3 - Medium - February 23, 2021

A flaw was found in PostgreSQL in versions before 13.2. This flaw allows a user with SELECT privilege on one column to craft a special query that returns all columns of the table. The highest threat from this vulnerability is to confidentiality.

AuthZ

A flaw was found in the psql interactive terminal of PostgreSQL in versions before 13.1

CVE-2020-25696 7.5 - High - November 23, 2020

A flaw was found in the psql interactive terminal of PostgreSQL in versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24. If an interactive psql session uses \gset when querying a compromised server, the attacker can execute arbitrary code as the operating system account running psql. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Incorrect Comparison

A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24

CVE-2020-25694 8.1 - High - November 16, 2020

A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24. If a client application that creates additional database connections only reuses the basic connection parameters while dropping security-relevant parameters, an opportunity for a man-in-the-middle attack, or the ability to observe clear-text transmissions, could exist. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Use of a Broken or Risky Cryptographic Algorithm

A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24

An attacker having permission to create non-temporary objects in at least one schema can execute arbitrary SQL functions under the identity of a superuser. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

SQL Injection

The Windows installer for PostgreSQL 9.5 - 12 invokes system-provided executables that do not have fully-qualified paths

CVE-2020-10733 7.3 - High - September 16, 2020

The Windows installer for PostgreSQL 9.5 - 12 invokes system-provided executables that do not have fully-qualified paths. Executables in the directory where the installer loads or the current working directory take precedence over the intended executables. An attacker having permission to add files into one of those directories can use this to execute arbitrary code with the installer's administrative rights.

Untrusted Path

It was found that some PostgreSQL extensions did not use search_path safely in their installation script

CVE-2020-14350 7.3 - High - August 24, 2020

It was found that some PostgreSQL extensions did not use search_path safely in their installation script. An attacker with sufficient privileges could use this flaw to trick an administrator into executing a specially crafted script, during the installation or update of such extension. This affects PostgreSQL versions before 12.4, before 11.9, before 10.14, before 9.6.19, and before 9.5.23.

Untrusted Path

It was found that PostgreSQL versions before 12.4

CVE-2020-14349 7.1 - High - August 24, 2020

It was found that PostgreSQL versions before 12.4, before 11.9 and before 10.14 did not properly sanitize the search_path during logical replication. An authenticated attacker could use this flaw in an attack similar to CVE-2018-1058, in order to execute arbitrary SQL command in the context of the user used for replication.

SQL Injection

PostgreSQL JDBC Driver (aka PgJDBC) before 42.2.13

CVE-2020-13692 7.7 - High - June 04, 2020

PostgreSQL JDBC Driver (aka PgJDBC) before 42.2.13 allows XXE.

This issue affects PostgreSQL versions before 12.2, before 11.7, before 10.12 and before 9.6.17.

AuthZ

The pg_ctlcluster script in postgresql-common in versions prior to 210 didn't drop privileges when creating socket/statistics temporary directories

CVE-2019-3466 7.8 - High - November 20, 2019

The pg_ctlcluster script in postgresql-common in versions prior to 210 didn't drop privileges when creating socket/statistics temporary directories, which could result in local privilege escalation.

Improper Privilege Management

Postgresql

CVE-2019-10209 2.2 - Low - October 29, 2019

Postgresql, versions 11.x before 11.5, is vulnerable to a memory disclosure in cross-type comparison for hashed subplan.

Information Disclosure

A flaw was discovered in postgresql versions 9.4.x before 9.4.24, 9.5.x before 9.5.19, 9.6.x before 9.6.15, 10.x before 10.10 and 11.x before 11.5 where arbitrary SQL statements

CVE-2019-10208 8.8 - High - October 29, 2019

A flaw was discovered in postgresql versions 9.4.x before 9.4.24, 9.5.x before 9.5.19, 9.6.x before 9.6.15, 10.x before 10.10 and 11.x before 11.5 where arbitrary SQL statements can be executed given a suitable SECURITY DEFINER function. An attacker, with EXECUTE permission on the function, can execute arbitrary SQL as the owner of the function.

SQL Injection

A vulnerability was found in postgresql versions 11.x prior to 11.3

CVE-2019-10129 6.5 - Medium - July 30, 2019

A vulnerability was found in postgresql versions 11.x prior to 11.3. Using a purpose-crafted insert to a partitioned table, an attacker can read arbitrary bytes of server memory. In the default configuration, any user can create a partitioned table suitable for this attack. (Exploit prerequisites are the same as for CVE-2018-1052).

Information Disclosure

A vulnerability was found in PostgreSQL versions 11.x up to excluding 11.3

CVE-2019-10130 4.3 - Medium - July 30, 2019

A vulnerability was found in PostgreSQL versions 11.x up to excluding 11.3, 10.x up to excluding 10.8, 9.6.x up to, excluding 9.6.13, 9.5.x up to, excluding 9.5.17. PostgreSQL maintains column statistics for tables. Certain statistics, such as histograms and lists of most common values, contain values taken from the column. PostgreSQL does not evaluate row security policies before consulting those statistics during query planning; an attacker can exploit this to read the most common values of certain columns. Affected columns are those for which the attacker has SELECT privilege and for which, in an ordinary query, row-level security prunes the set of rows visible to the attacker.

Authorization

PostgreSQL versions 10.x before 10.9 and versions 11.x before 11.4 are vulnerable to a stack-based buffer overflow

CVE-2019-10164 8.8 - High - June 26, 2019

PostgreSQL versions 10.x before 10.9 and versions 11.x before 11.4 are vulnerable to a stack-based buffer overflow. Any authenticated user can overflow a stack-based buffer by changing the user's own password to a purpose-crafted value. This often suffices to execute arbitrary code as the PostgreSQL operating system account.

Buffer Overflow

** DISPUTED ** In PostgreSQL 9.3 through 11.2, the "COPY TO/FROM PROGRAM" function

CVE-2019-9193 7.2 - High - April 01, 2019

** DISPUTED ** In PostgreSQL 9.3 through 11.2, the "COPY TO/FROM PROGRAM" function allows superusers and users in the 'pg_execute_server_program' group to execute arbitrary code in the context of the database's operating system user. This functionality is enabled by default and can be abused to run arbitrary operating system commands on Windows, Linux, and macOS. NOTE: Third parties claim/state this is not an issue because PostgreSQL functionality for COPY TO/FROM PROGRAM is acting as intended. References state that in PostgreSQL, a superuser can execute commands as the server user without using the COPY FROM PROGRAM.

Shell injection

postgresql before versions 11.1, 10.6 is vulnerable to a to SQL injection in pg_upgrade and pg_dump via CREATE TRIGGER

CVE-2018-16850 9.8 - Critical - November 13, 2018

postgresql before versions 11.1, 10.6 is vulnerable to a to SQL injection in pg_upgrade and pg_dump via CREATE TRIGGER ... REFERENCING. Using a purpose-crafted trigger definition, an attacker can cause arbitrary SQL statements to run, with superuser privileges.

SQL Injection

A weakness was found in postgresql-jdbc before version 42.2.5

CVE-2018-10936 8.1 - High - August 30, 2018

A weakness was found in postgresql-jdbc before version 42.2.5. It was possible to provide an SSL Factory and not check the host name if a host name verifier was not provided to the driver. This could lead to a condition where a man-in-the-middle attacker could masquerade as a trusted server by providing a certificate for the wrong host, as long as it was signed by a trusted CA.

Improper Validation of Certificate with Host Mismatch

It was discovered that PostgreSQL versions before 10.5

CVE-2018-10925 8.1 - High - August 09, 2018

It was discovered that PostgreSQL versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 failed to properly check authorization on certain statements involved with "INSERT ... ON CONFLICT DO UPDATE". An attacker with "CREATE TABLE" privileges could exploit this to read arbitrary bytes server memory. If the attacker also had certain "INSERT" and limited "UPDATE" privileges to a particular table, they could exploit this to update other columns in the same table.

AuthZ

A vulnerability was found in libpq

CVE-2018-10915 7.5 - High - August 09, 2018

A vulnerability was found in libpq, the default PostgreSQL client library where libpq failed to properly reset its internal state between connections. If an affected version of libpq was used with "host" or "hostaddr" connection parameters from untrusted input, attackers could bypass client-side connection security features, obtain access to higher privileged connections or potentially cause other impact through SQL injection, by causing the PQescape() functions to malfunction. Postgresql versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 are affected.

SQL Injection

postgresql before versions 10.4

CVE-2018-1115 9.1 - Critical - May 10, 2018

postgresql before versions 10.4, 9.6.9 is vulnerable in the adminpack extension, the pg_catalog.pg_logfile_rotate() function doesn't follow the same ACLs than pg_rorate_logfile. If the adminpack is added to a database, an attacker able to connect to it could exploit this to force log rotation.

Incorrect Permission Assignment for Critical Resource

A flaw was found in the way Postgresql allowed a user to modify the behavior of a query for other users

CVE-2018-1058 8.8 - High - March 02, 2018

A flaw was found in the way Postgresql allowed a user to modify the behavior of a query for other users. An attacker with a user account could use this flaw to execute code with the permissions of superuser in the database. Versions 9.3 through 10 are affected.

In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pg_upgrade creates file in current working directory containing the output of `pg_dumpall -g` under umask

CVE-2018-1053 7 - High - February 09, 2018

In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pg_upgrade creates file in current working directory containing the output of `pg_dumpall -g` under umask which was in effect when the user invoked pg_upgrade, and not under 0077 which is normally used for other temporary files. This can allow an authenticated attacker to read or modify the one file, which may contain encrypted or unencrypted database passwords. The attack is infeasible if a directory mode blocks the attacker searching the current working directory or if the prevailing umask blocks the attacker opening the file.

Incorrect Permission Assignment for Critical Resource

Memory disclosure vulnerability in table partitioning was found in postgresql 10.x before 10.2

CVE-2018-1052 6.5 - Medium - February 09, 2018

Memory disclosure vulnerability in table partitioning was found in postgresql 10.x before 10.2, allowing an authenticated attacker to read arbitrary bytes of server memory via purpose-crafted insert to a partitioned table.

Information Disclosure

Insecure directory permissions in RPM distribution for PostgreSQL

CVE-1999-0862 - December 02, 1999
