- Summary
- Apache Log4j Remote Code Execution
- Details
-
Impact
Opencast uses an Apache Log4j2 version which, combined with older JDK versions, can be used for remote code execution attacks which have been found to be actively exploited.
Apache Log4j2 <=2.14.1 JNDI features is not sufficiently protected. An attacker who can control log messages or log message parameters can execute arbitrary code when message lookup substitution is enabled.
Who is affected
- Opencast before 9.10 or 10.6 are affected
- Log4j version: all 2.x versions before 2.15.0 are affected
Patches
The issue has been fixed in Opencast 9.10 and 10.6.
Workarounds
