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
XR3Player version <= V3.124 contains a XML External Entity (XXE) vulnerability in Playlist parser that can result in Disclosure of confidential data, denial of service, SSRF, port scanning.

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

XR3Player version V3.124 and earlier contains an XML External Entity (XXE) vulnerability in its Playlist parser. The application parses XML playlist files without properly disabling external entity processing, allowing attackers to inject malicious XML that can read local files, perform SSRF attacks, port scanning, or cause denial of service.

MitigationDisable XML external entity (XXE) processing in the playlist parser's XML configuration by setting feature flags to prevent external entity resolution, and implement input validation for playlist files.

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. Check if XR3Player is installed
    Search for XR3Player executable or JAR file in common locations: user's home directory (~/XR3Player), Program Files (Windows), /opt or /usr/local (Linux). On Windows, check Start Menu shortcuts or uninstall registry. On Linux, check package manager listings (dpkg -l, rpm -qa).
    Affected if XR3Player is found installed on the system
  2. Verify the installed version
    Locate the XR3Player JAR or executable. If it's a JAR file, right-click and view properties, or run: java -jar XR3Player.jar --version 2>&1. Check any version file in the application directory.
    Affected if Version is 3.124 or earlier, or version cannot be determined (unknown versions should be treated as vulnerable)
  3. Identify playlist file usage
    Look for .xml playlist files that XR3Player uses. Check the application's data directory for playlist files (typically in ~/XR3Player/Playlists or similar). XR3Player uses XML format for playlists.
    Affected if XML playlist files are created, loaded, or parsed by XR3Player
  4. Confirm XML parsing without XXE protection
    Examine XR3Player's source code or configuration for XML parser initialization. Look for DocumentBuilderFactory or similar XML parsing code. Check if external entity processing is explicitly disabled using features like XMLConstants.FEATURE_SECURE_PROCESSING or setting 'external-general-entities' and 'external-parameter-entities' to false.
    Affected if XML parser is initialized without disabling external entity processing (XXE protection is not implemented)

A user is affected if XR3Player version 3.124 or earlier is installed and the application parses XML playlist files without XXE protection enabled in the XML parser configuration.
