| Titre | Tenda CH22 V1.0.0.1 Command Injection |
|---|
| Description | The Tenda CH22 V1.0.0.1 firmware has a command injection vulnerability in the formeditFileName function. The src variable receives the editNameMit parameter from a POST request and is later passed to the strcpy function. In this function, the src variable is passed as the s parameter.
The s parameter is used in a chain of strchr() calls to locate delimiter characters ('*'): v12 = strchr(s, 42); and v11 = strchr(v12 + 1, 42); . The content following the second '*' (i.e., v11 + 1) is then copied into the v7 buffer via strcpy(v7, v11 + 1);.
However, since the Since user can control the input of src, the statemeant doSystemCmd("/usr/sbin/EditDiskDir %s edit '%s' '%s' ", dest, v8, v7); can cause a command injection. |
