CVE-2024-5339Public exploitNetwork attack vector

Authenticated command execution via peernode injection

Published May 25, 2024 · Updated Aug 1, 2024

OS command injection in Ruijie RG-UAC 20240516 allows remote authenticated users to execute arbitrary commands through peernode. The /view/vpn/autovpn/online_check.php handler incorporates the peernode request parameter into an operating-system command without neutralizing shell metacharacters. Access requires a highly privileged authenticated session; injected commands can read, alter, or interrupt appliance operations.
