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
An issue in SourceBans Material Admin before v.1.1.6 (3ecd95e) allows attackers to manipulate arbitrary user data in the web app via a crafted XAJAX call.

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

This is a cross-site scripting (XSS) vulnerability in SourceBans Material Admin's XAJAX request handling. Attackers can inject malicious scripts or manipulate arbitrary user data through crafted XAJAX calls by exploiting insufficient input validation on XAJAX endpoints.

MitigationUpgrade to SourceBans Material Admin v1.1.6 or later (commit 3ecd95e). If immediate upgrade is not possible, implement input sanitization and validation on all XAJAX request handlers to prevent injection of malicious content.

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 SourceBans Material Admin installation
    Search for files matching 'sourcebans' in your web directory, typically under /var/www, /home, or C:\inetpub. Look for directories containing 'sourcebans' or 'material-admin' and a file named 'version.php' or 'info.php'.
    Affected if SourceBans Material Admin is not found in the expected directories, indicating it may not be installed.
  2. Identify installed version
    Open the version file (commonly version.php, info.php, or similar in the root/admin directory). Read the defined version constant or variable. Alternatively, check git log if the installation uses version control: run 'git log --oneline -1' to see the latest commit hash.
    Affected if The version is earlier than 1.1.6 or the commit hash precedes 3ecd95e.
  3. Confirm XAJAX module is enabled
    Search for XAJAX configuration in the SourceBans configuration files (often config.php, settings.php, or similar). Look for directives enabling xajax, ajax, or similar features. Also search for files containing 'xajax' in the codebase: run 'find . -iname "*xajax*"' or search for 'xajax' in PHP files.
    Affected if XAJAX functionality is present and enabled in the configuration.
  4. Inspect XAJAX request handlers for input validation
    Examine PHP files in the xajax or ajax handler directories. Look for functions processing user input (GET/POST parameters) without proper sanitization. Search for patterns like $_GET, $_POST being used directly in output or database queries without sanitization functions such as htmlspecialchars, strip_tags, or parameterized queries.
    Affected if XAJAX handlers accept user input without sanitization routines present in the code.

The environment is affected if SourceBans Material Admin is installed with a version earlier than 1.1.6 (or commit before 3ecd95e) and XAJAX request handling is enabled with insufficient input validation present in the handler code.
