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
The chcpass script in cPanel before 11.54.0.4 reveals a password hash (SEC-77).

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 · moderate confidence

The chcpass script in cPanel versions prior to 11.54.0.4 has an information disclosure vulnerability that exposes password hashes. An authenticated attacker with access to the script output or execution results could obtain password hashes, which could then be subjected to offline cracking attacks.

MitigationUpgrade cPanel to version 11.54.0.4 or later to obtain the patched chcpass script that no longer reveals password hashes.

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. Identify installed cPanel version
    Run `cat /usr/local/cpanel/version` or check the cPanel login banner/version display to determine the exact cPanel version number
    Affected if The installed version falls within one of these ranges: 11.48.0.5 to 11.48.5.2, 11.50.0.4 to 11.50.4.3, 11.51.9999.98 to 11.52.2.4, or 11.54.0.0 to 11.54.0.4
  2. Locate the chcpass script
    Find the chcpass script in the cPanel installation directory (typically in /scripts/ or /usr/local/cpanel/scripts/) using `find /usr/local/cpanel -name chcpass 2>/dev/null`
    Affected if The chcpass script exists and is present on the system
  3. Verify script output exposure
    As an authenticated cPanel user with access to command execution, run the chcpass script and examine its output for presence of password hash strings
    Affected if The script output contains plaintext or encoded password hash data that should not be visible

You are affected if your cPanel version is within the vulnerable ranges listed AND authenticated users can access the chcpass script output containing password hashes.
