GLSA-202312-02 : Minecraft Server: Remote Code Execution

high Nessus Plugin ID 187119

Language:

Description

The remote host is affected by the vulnerability described in GLSA-202312-02 (Minecraft Server: Remote Code Execution)

 - JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. (CVE-2021-4104)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

All Minecraft Server users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=games-server/minecraft-server-1.18.1
