Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A command injection vulnerability in ZPanel 10.0.0.2's htpasswd module allows authenticated attackers to execute arbitrary system commands by injecting shell metacharacters into the inHTUsername field, which is passed unsanitized to a system() call that invokes the htpasswd binary.

MitigationUpgrade ZPanel to a patched version or implement strict input validation to sanitize the username field before passing it to system() calls, preventing shell metacharacter injection.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Locate ZPanel installation and version
    Check for ZPanel installation directories (commonly /etc/zpanel, /var/zpanel, or C:\ZPanel) and look for version files or examine the admin interface for the installed version number.
    Affected if ZPanel version 10.0.0.2 is installed
  2. Identify htpasswd module presence
    Look for the htpasswd management module within the ZPanel modules directory - typically found under the admin or password management sections.
    Affected if The htpasswd module is present and accessible in the ZPanel installation
  3. Examine htpasswd module code for vulnerable system call
    Inspect the htpasswd module source code (typically a .php file) for direct system() function calls that use the inHTUsername form input without sanitization.
    Affected if The module code contains system() calls that pass user-supplied username input directly to the shell
  4. Verify the vulnerable parameter name
    Search the htpasswd module code for the inHTUsername parameter being used within system() or exec() functions without proper escaping or validation.
    Affected if The inHTUsername parameter is passed unsanitized to a shell-executing function

Your environment is affected if ZPanel version 10.0.0.2 is installed with the htpasswd module enabled and the module code contains unsanitized system() calls using the inHTUsername parameter.
