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
IceWarp WebClient DC2 - Update 2 Build 9 (13.0.2.9) was discovered to contain a SQL injection vulnerability via the search parameter at /webmail/server/webmail.php.

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

A SQL injection vulnerability exists in IceWarp WebClient version 13.0.2.9 (Build 9) in the search parameter at /webmail/server/webmail.php. The unsanitized search parameter allows attackers to inject malicious SQL queries, potentially enabling unauthorized data access, modification, or complete database compromise.

MitigationUpgrade to the latest IceWarp WebClient version with security patches applied. As an immediate workaround, implement input validation and use parameterized queries for all database interactions.

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 IceWarp WebClient version
    Locate the version file or check the webmail.php header for the build version, typically found in the /webmail/server/ directory or accessed via the web interface login page
    Affected if The installed version is IceWarp WebClient 13.0.2.9 (Build 9)
  2. Verify webmail.php endpoint exists
    Check for the presence of the file /webmail/server/webmail.php in the web root directory
    Affected if The file webmail.php exists and is accessible via the web server
  3. Confirm search parameter is available
    Make a GET or POST request to /webmail/server/webmail.php and verify the search parameter is accepted
    Affected if The search parameter is accepted by the endpoint without additional authentication or sanitization checks
  4. Inspect web server access logs
    Review web server logs (Apache, IIS, or nginx) for requests to /webmail/server/webmail.php with unusual patterns in the search parameter
    Affected if Log entries show unescaped SQL characters or abnormal query patterns in the search parameter

You are affected if IceWarp WebClient version 13.0.2.9 is installed and the /webmail/server/webmail.php endpoint with the search parameter is accessible.
