TitleTenda CH22 V1.0.0.1 Command Injection
DescriptionThe Tenda CH22 V1.0.0.1 firmware has a command injection vulnerability in the `formCertListInfo` function. The `v12` variable receives the `name` parameter from a POST request and is later passed to the `sub_517E8` function. In function sub_517E8, the variable v12 is directly assigned to system by doSystemCmd However, since the Since user can control the input of v12, the statemeant doSystemCmd("rm /etc/cert/%s.key 2> /dev/null", a1); can cause a command injection.
