Lifecycle Timeline
3DescriptionCVE.org
Multiple DrayTek VigorAP models contain a command injection vulnerability in the apautotest function. The vulnerability is caused by insufficient validation of the CMD0, CMD3, and CMD6 fields before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface.
AnalysisAI
Command injection in the apautotest function of multiple DrayTek VigorAP access point models allows a remote attacker holding valid administrative credentials to execute arbitrary OS commands with root privileges. Six CPE-confirmed models across the VigorAP 903, 906, 912C, 918R, 960C, and 1060C series are affected in all firmware versions below their respective patch thresholds. …
