## Technical details

This vulnerability is a command injection flaw in the PPPoE configuration module of GeoVision GV-LPC2211 V1.13. The vulnerability arises because the PPPoE username input is improperly sanitized before being incorporated into a shell configuration assignment and sourced for execution. An authenticated administrator can inject shell metacharacters (such as backticks or command substitution syntax) into the PPPoE username field to break out of the intended variable assignment context and execute arbitrary commands as root. No network-level authentication bypass is required—the attacker must have administrative access to the device. A successful exploit grants complete system compromise with root-level command execution.
