A security flaw has been discovered in Tenda F451 1.0.0.7/1.0.0.9. Impacted is the function formWriteFacMac of the file /goform/WriteFacMac of the component Web Management Interface. Performing a manipulation of the argument mac results in os command injection. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks.
AnalysisAI
OS command injection in Tenda F451 routers (firmware 1.0.0.7 and 1.0.0.9) allows remote attackers with low-privileged web management access to execute arbitrary operating system commands by manipulating the 'mac' parameter sent to the /goform/WriteFacMac endpoint handled by the formWriteFacMac function. Publicly available exploit code exists, raising the practical risk for any device exposing the web management interface to untrusted networks. …
