Description
Tenda G300-F router firmware version 16.01.14.2 and prior contain an OS command injection vulnerability in the WAN diagnostic functionality (formSetWanDiag). The implementation constructs a shell command that invokes curl and incorporates attacker-controlled input into the command line without adequate neutralization. As a result, a remote attacker with access to the affected management interface can inject additional shell syntax and execute arbitrary commands on the device with the privileges of the management process.
Affected configurations
• tenda g300-f firmware (<= 16.01.14.2)
