| Title | Tenda CH22 V1.0.0.1 Command Injection |
|---|
| Description | The Tenda CH22 V1.0.0.1 firmware has a command injection vulnerability in the formcreateFileName function. The s variable receives the fileNameMit parameter from a POST request and is later passed to the v4 = strtok(s, "*"); function. The variable v4 is directly assigned to system by doSystemCmd However, since the Since user can control the input of fileNameMit, the statemeant doSystemCmd("/usr/sbin/EditDiskDir %s add '%s' ", v4, v3); can cause a command injection. |
