Lifecycle Timeline
3DescriptionCVE.org
Multiple DrayTek VigorAP models contain a command injection vulnerability in the InquierTime function. The vulnerability is caused by insufficient filtering of the time field 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 DrayTek VigorAP series access points (models 903, 906, 912C, 918R, 960C, and 1060C) allows an authenticated remote attacker to execute arbitrary OS commands with root privileges by submitting crafted input to the InquierTime function's time field via the web management interface. The root cause is CWE-78 (Improper Neutralization of Special Elements used in an OS Command) - the time parameter is passed to a system shell without adequate filtering, enabling shell metacharacter injection. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires valid administrative credentials for the DrayTek VigorAP web management interface - confirmed by CVSS PR:H. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.6 (AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H) reflects full CIA impact on the vulnerable system over the network, but PR:H is the critical limiting factor - exploitation unconditionally requires valid administrative credentials. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade each affected model to its respective patched firmware release: VigorAP 918R to 1.4.11 or later, VigorAP 960C to 1.4.12 or later, VigorAP 1060C to 1.4.12 or later, VigorAP 906 to 1.4.13 or later, VigorAP 912C to 1.4.15 or later, and VigorAP 903 to 1.4.22 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
