UBUNTU-CVE-2024-12798 (CVE-2024-12798)

Vulnerability from osv_ubuntu – Published: 2024-12-19 16:15 – Updated: 2026-01-20 05:17 – Source website

Details

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.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
