Apache James prior to versions 3.8.1 and 3.7.5 is vulnerable to SMTP smuggling

CVE-2023-51747 - February 27, 2024

Apache James prior to versions 3.8.1 and 3.7.5 is vulnerable to SMTP smuggling. A lenient behaviour in line delimiter handling might create a difference of interpretation between the sender and the receiver which can be exploited by an attacker to forge an SMTP envelop, allowing for instance to bypass SPF checks. The patch implies enforcement of CRLF as a line delimiter as part of the DATA transaction. We recommend James users to upgrade to non vulnerable versions.

Improper Input Validation

Apache James prior to version 3.7.5 and 3.8.0 exposes a JMX endpoint on localhost subject to pre-authentication deserialisation of untrusted data

CVE-2023-51518 - February 27, 2024

Apache James prior to version 3.7.5 and 3.8.0 exposes a JMX endpoint on localhost subject to pre-authentication deserialisation of untrusted data. Given a deserialisation gadjet, this could be leveraged as part of an exploit chain that could result in privilege escalation. Note that by default JMX endpoint is only bound locally. We recommend users to:  - Upgrade to a non-vulnerable Apache James version  - Run Apache James isolated from other processes (docker - dedicated virtual machine)  - If possible turn off JMX

Marshaling, Unmarshaling

Apache James server version 3.7.3 and earlier provides a JMX management service without authentication by default

CVE-2023-26269 7.8 - High - April 03, 2023

Apache James server version 3.7.3 and earlier provides a JMX management service without authentication by default. This allows privilege escalation by a malicious local user. Administrators are advised to disable JMX, or set up a JMX password. Note that version 3.7.4 onward will set up a JMX password automatically for Guice users.

AuthZ

Usage of temporary files with insecure permissions by the Apache James server

CVE-2022-45935 5.5 - Medium - January 06, 2023

Usage of temporary files with insecure permissions by the Apache James server allows an attacker with local access to access private user data in transit. Vulnerable components includes the SMTP stack and IMAP APPEND command. This issue affects Apache James server version 3.7.2 and prior versions.

Exposure of Resource to Wrong Sphere

Unproper laxist permissions on the temporary files used by MIME4J TempFileStorageProvider may lead to information disclosure to other local users

CVE-2022-45787 5.5 - Medium - January 06, 2023

Unproper laxist permissions on the temporary files used by MIME4J TempFileStorageProvider may lead to information disclosure to other local users. This issue affects Apache James MIME4J version 0.8.8 and prior versions. We recommend users to upgrade to MIME4j version 0.8.9 or later.

Cleartext Storage of Sensitive Information

Apache James prior to release 3.6.3 and 3.7.1 is vulnerable to a buffering attack relying on the use of the STARTTLS command

CVE-2022-28220 7.5 - High - September 08, 2022

Apache James prior to release 3.6.3 and 3.7.1 is vulnerable to a buffering attack relying on the use of the STARTTLS command. Fix of CVE-2021-38542, which solved similar problem fron Apache James 3.6.1, is subject to a parser differential and do not take into account concurrent requests.

Command Injection

Fix of CVE-2021-40525 do not prepend delimiters upon valid directory validations

CVE-2022-22931 4.3 - Medium - February 07, 2022

Fix of CVE-2021-40525 do not prepend delimiters upon valid directory validations. Affected implementations include: - maildir mailbox store - Sieve file repository This enables a user to access other users data stores (limited to user names being prefixed by the value of the username being used).

Directory traversal

Apache James ManagedSieve implementation alongside with the file storage for sieve scripts is vulnerable to path traversal

CVE-2021-40525 9.1 - Critical - January 04, 2022

Apache James ManagedSieve implementation alongside with the file storage for sieve scripts is vulnerable to path traversal, allowing reading and writing any file. This vulnerability had been patched in Apache James 3.6.1 and higher. We recommend the upgrade. Distributed and Cassandra based products are also not impacted.

Directory traversal

In Apache James, while fuzzing with Jazzer the IMAP parsing stack, we discover

CVE-2021-40111 6.5 - Medium - January 04, 2022

In Apache James, while fuzzing with Jazzer the IMAP parsing stack, we discover that crafted APPEND and STATUS IMAP command could be used to trigger infinite loops resulting in expensive CPU computations and OutOfMemory exceptions. This can be used for a Denial Of Service attack. The IMAP user needs to be authenticated to exploit this vulnerability. This affected Apache James prior to version 3.6.1. This vulnerability had been patched in Apache James 3.6.1 and higher. We recommend the upgrade.

Infinite Loop

In Apache James, using Jazzer fuzzer, we identified

CVE-2021-40110 7.5 - High - January 04, 2022

In Apache James, using Jazzer fuzzer, we identified that an IMAP user can craft IMAP LIST commands to orchestrate a Denial Of Service using a vulnerable Regular expression. This affected Apache James prior to 3.6.1 We recommend upgrading to Apache James 3.6.1 or higher , which enforce the use of RE2J regular expression engine to execute regex in linear time without back-tracking.

Apache James prior to release 3.6.1 is vulnerable to a buffering attack relying on the use of the STARTTLS command

CVE-2021-38542 5.9 - Medium - January 04, 2022

Apache James prior to release 3.6.1 is vulnerable to a buffering attack relying on the use of the STARTTLS command. This can result in Man-in -the-middle command injection attacks, leading potentially to leakage of sensible information.

CVE-2019-0228 9.8 - Critical - April 17, 2019

Apache PDFBox 2.0.14 does not properly initialize the XML parser, which allows context-dependent attackers to conduct XML External Entity (XXE) attacks via a crafted XFDF.
