Lifecycle Timeline
3DescriptionCVE.org
Multiple DrayTek VigorAP models contain a command injection vulnerability in the setcamset function. The vulnerability is caused by insufficient filtering of the selectSlaves 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 wireless access points allows authenticated remote administrators to execute arbitrary OS commands with root privileges by submitting crafted input to the setcamset function via the web management interface. Six distinct VigorAP models are confirmed affected across multiple firmware branches, each with a separate patch target version released in August 2026. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires valid administrative credentials for the DrayTek VigorAP web management interface (PR:H per CVSS 4.0 vector) - this is a hard prerequisite, not a soft configuration dependency. … 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/SC:N/SI:N/SA:N) accurately reflects the threat profile: network-reachable, low complexity, no user interaction, but requiring high privileges (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 | The primary fix is upgrading affected VigorAP firmware to the patched versions released by DrayTek in August 2026: VigorAP 1060C to 1.4.12 or later, VigorAP 918R to 1.4.11 or later, VigorAP 912C to 1.4.15 or later, VigorAP 960C to 1.4.12 or later, VigorAP 906 to 1.4.13 or later, and VigorAP 903 to 1.4.22 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
