CVE-2013-20006 — Qool CMS security vulnerability

High CVSS 8.7

Qool CMS contains multiple persistent cross-site scripting vulnerabilities in several administrative scripts where POST parameters are not properly sanitized before being stored and returned to users. Attackers can inject malicious JavaScript code through parameters like 'title', 'name', 'email', 'username', 'link', and 'task' in endpoints such as addnewtype, addnewdatafield, addmenu, addusergroup, addnewuserfield, adduser, addgeneraldata, and addcontentitem to execute arbitrary scripts in administrator browsers.

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
