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
Buffer overflow in cgi.c in www-sql before 0.5.7 allows local users to execute arbitrary code via a web page that is processed by www-sql.

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

Buffer overflow vulnerability in the cgi.c component of www-sql (versions prior to 0.5.7) allows local users to execute arbitrary code through a maliciously crafted web page processed by the application. The overflow occurs when handling web input in the CGI module.

MitigationUpgrade www-sql to version 0.5.7 or later to obtain the patched version. Avoid processing untrusted web pages with vulnerable versions until upgrade is complete.

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 www-sql version
    Run 'dpkg -l www-sql' on Debian systems, or check the application binary/version file if installed from source. Compare the version number against the affected range (prior to 0.5.7).
    Affected if The installed version is less than 0.5.7 or cannot be determined to be 0.5.7 or later.
  2. Locate the cgi.c component
    Search for the cgi.c source file or compiled CGI module in the www-sql installation directory, typically under /usr/lib/www-sql, /var/www, or the application source tree.
    Affected if The cgi.c component exists in the installation and matches the vulnerable codebase.
  3. Determine if CGI module is in use
    Inspect the web server configuration (Apache httpd.conf, nginx config, or equivalent) for CGI script mappings or aliases pointing to www-sql binaries.
    Affected if CGI processing for www-sql is enabled and accessible via the web server.
  4. Verify web input handling is active
    Check whether www-sql is configured to process web-facing requests or parse web page content, as the overflow occurs when handling web input.
    Affected if The application accepts and processes web input through its CGI interface.

You are affected if www-sql version is prior to 0.5.7 AND the CGI module is actively processing web requests.
