ZPanel <= 10.0.0.2 htpasswd Module Username Command Execution

Published Aug 1, 2025 CVSS 4.0 · 8.7 High EPSS 1.8% KEV · Not listed
Description
A remote command execution vulnerability exists in ZPanel version 10.0.0.2 in its htpasswd module. When creating .htaccess files, the inHTUsername field is passed unsanitized to a system() call that invokes the system’s htpasswd binary. By injecting shell metacharacters into the username field, an authenticated attacker can execute arbitrary system commands. Exploitation requires a valid ZPanel account—such as one in the default Users, Resellers, or Administrators groups—but no elevated privileges.
