CVE-2016-10780
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 · uneditedcPanel before 60.0.25 allows stored XSS in the ftp_sessions API (SEC-180).
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 confidenceThis is a stored Cross-Site Scripting (XSS) vulnerability in cPanel's ftp_sessions API that affects versions prior to 60.0.25. The vulnerability allows an attacker to inject malicious scripts that are persisted on the server and executed when other users access the ftp_sessions functionality.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the installed cPanel versionAccess the cPanel server via SSH and run: /usr/local/cpanel/cpanel -V or check /usr/local/cpanel/versionAffected if The version falls within any of these ranges: 11.54.0.0-11.54.0.32, 55.9999.61-56.0.38, 57.9999.48-58.0.36, or 59.9999.58-60.0.24
-
Verify ftp_sessions API accessibilityCheck if the ftp_sessions API endpoint is exposed or accessible in your cPanel environment. This may require reviewing API documentation or consulting cPanel configuration files.Affected if The ftp_sessions API is enabled and accessible to users without additional security restrictions
-
Review ftp session logs and stored dataExamine cPanel logs related to ftp_sessions for any suspicious script tags or unusual character sequences in session data. Look in /var/log/ directories or cPanel-specific log locations.Affected if Log entries or stored session data contain unsanitized HTML or JavaScript payloads, such as <script> tags or event handlers like onload= or onerror=
You are affected if your cPanel version is less than 60.0.25 (or within any of the other listed vulnerable version ranges) AND the ftp_sessions API is accessible in your environment.
