CVE-2024-4503Public exploitNetwork attack vector

Authenticated command execution via unsanitized interface_from parameter

Published May 5, 2024 · Updated Aug 1, 2024

OS command injection in Ruijie Networks RG-UAC 20240428 allows remote authenticated users to execute commands through interface_from. The dhcp_relay_commit.php handler passes the interface_from value into an operating-system command without neutralizing command metacharacters. Administrative privileges and network access to the management endpoint are required, and successful exploitation can read or alter data or interrupt the appliance.
