Command Injection in Tenda G0 routers with firmware versions v15.11.0.6(9039)CN and v15.11.0.5(5876)CN , and Tenda G1 and G3 routers with firmware versions v15.11.0.17(9502)CN or v15.11.0.16(9024)CN allows remote attackers to execute arbitrary OS commands via a crafted action/setDebugCfg request. This occurs because the "formSetDebugCfg" function executes glibc's system function with untrusted input.

Command Injection in Tenda G1 and G3 routers with firmware versions v15.11.0.17(9502)CN or v15.11.0.16(9024)CN allows remote attackers to execute arbitrary OS commands via a crafted "action/umountUSBPartition" request.
