CVE-2025-34143Known exploitationPublic exploitNetwork attack vector

Unauthenticated code execution via trailing-space SYSTEM login

Published Jul 22, 2025 · Updated May 15, 2026

Authentication bypass in ETQ Reliance CG before MP-4583 allows remote attackers to execute code through the public login page. UserManager.java checks the raw name against SYSTEM before trimming, but MySQL resolves the trailing-space variant to that internal account and password verification is then skipped. Network access to the login page is sufficient to gain a SYSTEM session and alter executable Jython report scripts, yielding server-side code execution.
