NVD Description

Note: Versions mentioned in the description apply only to the upstream log4j-javadoc package and not the log4j-javadoc package as distributed by SLES.

Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.
