Internal network mapping via unfiltered URL parameter
Published Oct 18, 2022 · Updated May 9, 2025
SSRF in CHANGING Information Technology RAVA Certificate Validation System 3 allows remote attackers to map internal networks via a URL parameter. URL-parameter filtering accepts attacker-controlled destinations, causing the validation server to issue requests whose responses reveal reachable internal hosts. No authentication or user interaction is required; the published consequence is limited to internal-network topology disclosure through query responses.
