Apache James: denial of service through JMAP HTML to text conversion

Apache James server JMAP HTML to text plain implementation in versions below 3.8.2 and 3.7.6 is subject to unbounded memory consumption that can result in a denial of service. Users are recommended to upgrade to version 3.7.6 and 3.8.2, which fix this issue.

Apache James: denial of service through the use of IMAP literals

Similarly to CVE-2024-34055, Apache James is vulnerable to denial of service through the abuse of IMAP literals from both authenticated and unauthenticated users, which could be used to cause unbounded memory allocation and very long computations Version 3.7.6 and 3.8.2 restrict such illegitimate use of IMAP literals.

The JMX server embedded in Apache James, also used by the command line client is exposed to a java de-serialization issue, and thus can be used to execute arbitrary commands. As James exposes JMX socket by default only on local-host, this vulnerability can only be used for privilege escalation. Release 3.0.1 upgrades the incriminated library.

Apache James Server 2.3.2, when configured with file-based user repositories, allows attackers to execute arbitrary system commands via unspecified vectors.

Apache James server: Privilege escalation through unauthenticated JMX

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.
