CVE-2024-12798

ACE vulnerability in JaninoEventEvaluator by QOS.CH logback-core
upto and including version 1.5.12 in Java applications allows
attacker to execute arbitrary code by compromising an existing
logback configuration file or by injecting an environment variable
before program execution.





Malicious logback configuration files can allow the attacker to execute
arbitrary code using the JaninoEventEvaluator extension.



A successful attack requires the user to have write access to a
configuration file. Alternatively, the attacker could inject a malicious
environment variable pointing to a malicious configuration file. In both
cases, the attack requires existing privilege.
