Executive brief
DrayTek VigorAP wireless access points are used to provide network connectivity in corporate and enterprise environments. An authenticated administrator with web management access can exploit a command injection vulnerability in the setcamset function to execute arbitrary commands with root privileges, potentially compromising the device and all connected network traffic.
Technical details
The vulnerability is an OS command injection flaw (CWE-78) in the setcamset function caused by insufficient input filtering on the selectSlaves parameter before command execution. Attack vector is network-based, but exploitation requires valid administrative credentials and authentication to the device's web management interface. A successful exploit allows an attacker to execute arbitrary system commands with root privileges. Patches are available in fixed firmware versions: VigorAP 918R 1.4.11, VigorAP 960C/1060C 1.4.12, VigorAP 906 1.4.13, VigorAP 912C 1.4.15, and VigorAP 903 1.4.22.
