CVE-2024-23049Network attack vector

Remote code execution via insecure Log4j component

Published Feb 5, 2024 · Updated Jun 17, 2025

Command injection in B3log Symphony 3.6.3 and earlier allows remote attackers to execute arbitrary code through its Log4j component. The upstream issue identifies /activity/character/submit as the trigger and attributes execution to an insecure Log4j version, but it does not disclose the exact logging call or input transformation. Network access without authentication or user interaction is sufficient, and successful exploitation permits server takeover.
