Deeper analysis
Tenda F1203 firmware version 2.0.1.6 contains an OS command injection vulnerability, tracked as CWE-78, in the mac parameter processed by the /goform/WriteFacMac endpoint. The flaw received a CVSS 3.1 base score of 9.8, reflecting network attack vector, low attack complexity, and no required authentication or user interaction.
Remote unauthenticated attackers can supply a crafted mac value to the web interface and execute arbitrary operating-system commands on the device, resulting in complete compromise of confidentiality, integrity, and availability. The two reference URLs point to the same public proof-of-concept repository that demonstrates the injection but contain no vendor advisory, patch information, or mitigation guidance. The associated EPSS score has remained flat at 0.1836 with no material rise after disclosure.
