A successful attack requires the presence of Janino library to be present on the user's class path. In addition, the attacker must 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.

Solution
Remove Janino from the Java classpath or update to logack version 1.5.37 or later. As of logback 1.5.20, the <condition> element with a custom PropertyEvaluator offers a recommended alternative to conditionals requiring Janino.

| Description | ACE vulnerability in conditional configuration file processing by QOS.CH logback-core up to and including version 1.5.35 in Java applications, allows an attacker to execute arbitrary code circumventing existing protections against CVE-2025-11226 by compromising an existing logback configuration file or by injecting an environment variable before program execution. A successful attack requires the presence of Janino library to be present on the user's class path. In addition, the attacker must 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. | ACE vulnerability in conditional configuration file processing by QOS.CH logback-core up to and including version 1.5.36 in Java applications, allows an attacker to execute arbitrary code circumventing existing protections against CVE-2025-11226 by compromising an existing logback configuration file or by injecting an environment variable before program execution. A successful attack requires the presence of Janino library to be present on the user's class path. In addition, the attacker must 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. Please note that in logack version 1.5.37 conditional processing using Janino was removed. |
