CVE-2024-33898Public exploitNetwork attack vector

Unauthenticated code execution via logout suffix bypass

Published Jun 24, 2024 · Updated Feb 6, 2025

Improper access control in Axiros AXESS 4.x and 5.0.0 allows remote attackers to execute code through protected API endpoints. AXUserManager treats any request URL ending in logout.html as authorized, so adding ?logout.html lets the anonymous nobody account reach protected endpoints. The exposed csvlog endpoint can then write a Python web shell into the live API tree, giving unauthenticated network attackers operating-system command execution.
