JaninoEventEvaluator vulnerability

ACE vulnerability in JaninoEventEvaluator by QOS.CH logback-core

upto including version 0.1 to 1.3.14 and 1.4.0 to 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.
