| Título | UTT (艾泰) UTT521G NV521Gv2v3.1.1-190816 Command Injection |
|---|
| Descrição | A command injection vulnerability was discovered in the sub_446B18 handler of the UTT 521G router, which is mapped to the /goform/formPdbUpConfig endpoint. The vulnerability exists due to the insecure handling of the policyNames parameter. When a specially crafted POST request containing shell metacharacters (e.g., 1;touch /tmp/1) is sent to this endpoint, the backend fails to sanitize the input before passing it to a system-level command execution function. This allows an authenticated attacker to execute arbitrary OS commands as the root user. Successful exploitation can be verified by checking for the creation of a file in the /tmp directory via a Telnet session. |
