CVE-2024-57546Public exploitNetwork attack vector

Internal service probing via link-validation SSRF

Published Jan 27, 2025 · Updated Jan 28, 2025

Server-side request forgery in CMSimple 5.16 allows remote authenticated users to probe internal services through link validation. The Validate links function sends a server-side request to an administrator-supplied page link and exposes reachability through its error result. Administrator access to edit a page and insert the link is required; the demonstrated consequence is internal-host discovery rather than response-body disclosure.
