ProFTPD Supplemental Group Inheritance Privilege Escalation Vulnerability

CVE-2024-48651 - November 29, 2024

In ProFTPD through 1.3.8b before cec01cc, supplemental group inheritance grants unintended access to GID 0 because of the lack of supplemental groups from mod_sql.

make_ftp_cmd in main.c in ProFTPD before 1.3.8a has a one-byte out-of-bounds read, and daemon crash

CVE-2023-51713 7.5 - High - December 22, 2023

make_ftp_cmd in main.c in ProFTPD before 1.3.8a has a one-byte out-of-bounds read, and daemon crash, because of mishandling of quote/backslash semantics.

CVE-2023-48795 5.9 - Medium - December 18, 2023

The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

Improper Validation of Integrity Check Value

mod_radius in ProFTPD before 1.3.7c

CVE-2021-46854 7.5 - High - November 23, 2022

mod_radius in ProFTPD before 1.3.7c allows memory disclosure to RADIUS servers because it copies blocks of 16 characters.

Memory Leak

ProFTPD 1.3.7 has an out-of-bounds (OOB) read vulnerability in mod_cap

CVE-2020-9272 7.5 - High - February 20, 2020

ProFTPD 1.3.7 has an out-of-bounds (OOB) read vulnerability in mod_cap via the cap_text.c cap_to_text function.

Out-of-bounds Read

In ProFTPD 1.3.7, it is possible to corrupt the memory pool by interrupting the data transfer channel

CVE-2020-9273 8.8 - High - February 20, 2020

In ProFTPD 1.3.7, it is possible to corrupt the memory pool by interrupting the data transfer channel. This triggers a use-after-free in alloc_pool in pool.c, and possible remote code execution.

Dangling pointer

An issue was discovered in tls_verify_crl in ProFTPD through 1.3.6b

CVE-2019-19269 4.9 - Medium - November 30, 2019

An issue was discovered in tls_verify_crl in ProFTPD through 1.3.6b. A dereference of a NULL pointer may occur. This pointer is returned by the OpenSSL sk_X509_REVOKED_value() function when encountering an empty CRL installed by a system administrator. The dereference occurs when validating the certificate of a client connecting to the server in a TLS client/server mutual-authentication setup.

NULL Pointer Dereference

An issue was discovered in tls_verify_crl in ProFTPD through 1.3.6b

CVE-2019-19270 7.5 - High - November 26, 2019

An issue was discovered in tls_verify_crl in ProFTPD through 1.3.6b. Failure to check for the appropriate field of a CRL entry (checking twice for subject, rather than once for subject and once for issuer) prevents some valid CRLs from being taken into account, and can allow clients whose certificates have been revoked to proceed with a connection to the server.

Improper Certificate Validation

An issue was discovered in tls_verify_crl in ProFTPD before 1.3.6

CVE-2019-19271 7.5 - High - November 26, 2019

An issue was discovered in tls_verify_crl in ProFTPD before 1.3.6. A wrong iteration variable, used when checking a client certificate against CRL entries (installed by a system administrator), can cause some CRL entries to be ignored, and can allow clients whose certificates have been revoked to proceed with a connection to the server.

Improper Certificate Validation

An issue was discovered in tls_verify_crl in ProFTPD before 1.3.6

CVE-2019-19272 7.5 - High - November 26, 2019

An issue was discovered in tls_verify_crl in ProFTPD before 1.3.6. Direct dereference of a NULL pointer (a variable initialized to NULL) leads to a crash when validating the certificate of a client connecting to the server in a TLS client/server mutual-authentication setup.

NULL Pointer Dereference

ProFTPD before 1.3.6b and 1.3.7rc before 1.3.7rc2

CVE-2019-18217 7.5 - High - October 21, 2019

ProFTPD before 1.3.6b and 1.3.7rc before 1.3.7rc2 allows remote unauthenticated denial-of-service due to incorrect handling of overly long commands because main.c in a child process enters an infinite loop.

Infinite Loop

CVE-2019-12815 9.8 - Critical - July 19, 2019

An arbitrary file copy vulnerability in mod_copy in ProFTPD up to 1.3.5b allows for remote code execution and information disclosure without authentication, a related issue to CVE-2015-3306.

Improper Handling of Exceptional Conditions

The mod_copy module in ProFTPD 1.3.5

CVE-2015-3306 - May 18, 2015

The mod_copy module in ProFTPD 1.3.5 allows remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands.

CVE-2004-1602 - October 15, 2004

ProFTPD 1.2.x, including 1.2.8 and 1.2.10, responds in a different amount of time when a given username exists, which allows remote attackers to identify valid usernames by timing the server response.

Side Channel Attack

Memory leak in ProFTPd 1.2.0rc2

CVE-2001-0136 - March 12, 2001

Memory leak in ProFTPd 1.2.0rc2 allows remote attackers to cause a denial of service via a series of USER commands, and possibly SIZE commands if the server has been improperly installed.
