Lifecycle Timeline
9DescriptionCVE.org
Multiple DrayTek VigorAP models contain a command injection vulnerability in the ExportSettings function. The vulnerability is caused by insufficient filtering of the backupkey, backuptype, and realtime 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 DrayTek VigorAP series access points allows an authenticated remote attacker with administrative credentials to execute arbitrary OS commands as root via the ExportSettings function. Insufficient input sanitization of the backupkey, backuptype, and realtime parameters permits shell metacharacter injection before those values are passed to a system command. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires valid administrative credentials for the VigorAP web management interface - this is explicitly stated in the CVE description and reflected in the CVSS 4.0 PR:H metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:H/UI:N) scores 8.6, reflecting network-accessible exploitation without special conditions but requiring high privileges (valid admin 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 to upgrade each affected model to its respective patched firmware version: VigorAP 903 to 1.4.22 or later, VigorAP 906 to 1.4.13 or later, VigorAP 912C to 1.4.15 or later, VigorAP 918R to 1.4.11 or later, VigorAP 960C to 1.4.12 or later, and VigorAP 1060C to 1.4.12 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all DrayTek VigorAP series devices in your environment and review administrative access logs for suspicious activity; reset or strengthen all administrative credentials given the root-level code execution risk. …
