| Title | UTT HiPER 520 nv520v3v1.7.7-160105 Command Injection |
|---|
| Description | A critical command injection vulnerability was discovered in the UTT HiPER 520 router with firmware version nv520v3v1.7.7-160105.
The issue is located in the web management interface's component /goform/formPdbUpConfig. The system fails to sanitize the user-supplied input in the policyNames POST parameter before passing it to a system shell command.
An authenticated remote attacker can exploit this by sending a crafted HTTP POST request. For example, injecting shell metacharacters such as a semicolon (;) followed by arbitrary OS commands (e.g., policyNames=AnyValue;whoami) allows for unauthorized command execution with root privileges.
This vulnerability can lead to a full system compromise, allowing attackers to intercept traffic, modify configurations, or maintain persistent access to the network. |
