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
cPanel before 60.0.25 allows format-string injection in exception-message handling (SEC-171).

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

cPanel before 60.0.25 contains a format-string injection vulnerability in its exception-message handling (SEC-171). This allows attackers to potentially read from or write to memory via specially crafted format specifiers in input that gets passed to formatting functions without proper sanitization.

MitigationUpgrade cPanel to version 60.0.25 or later to patch the format-string vulnerability in exception-message handling.

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. Verify cPanel is installed
    Identify whether the target system has cPanel software installed. Common methods include checking for cPanel-related processes, directories, or RPM packages.
    Affected if cPanel is not present on the system, this CVE does not apply.
  2. Determine the installed cPanel version
    Retrieve the currently installed cPanel version using system commands or configuration files that store cPanel version information.
    Affected if Unable to determine the version - further investigation is needed.
  3. Compare version against the affected range
    Check if the installed version falls within >= 59.9999.58 and < 60.0.25. This specific range represents versions known to contain the format-string vulnerability.
    Affected if Version is 59.9999.58 or higher AND lower than 60.0.25 - the environment is affected by this CVE.
  4. Confirm exception-message handling is in use
    Identify whether the cPanel exception-message handling feature is enabled or actively processing user-supplied input that could contain format specifiers.
    Affected if Exception-message handling is enabled and processing unsanitized input - the vulnerability is exploitable in this environment.

A system is affected if it runs cPanel with version 59.9999.58 or higher but lower than 60.0.25 and has exception-message handling enabled.
