CVE-2023-53872Public exploitNetwork attack vector

Unauthenticated command execution via unquoted numara input

Published Dec 15, 2025 · Updated Dec 15, 2025

OS command injection in Wp2Fac 1.0 allows remote attackers to execute arbitrary system commands through the numara POST parameter. send.php forwards the unvalidated value to server/run.php, where shell_exec interpolates it unquoted into a py command. No authentication is required; shell metacharacters such as ampersands run commands with the server process's privileges.
