Internal network access via server-side request forgery
Published Aug 11, 2025 · Updated Aug 12, 2025
SSRF in Omnissa Secure Email Gateway before 2.32 on Windows and before 2503 on UAG allows remote attackers to route HTTP requests internally. Omnissa has not disclosed the affected request handler or how attacker-controlled destinations bypass validation. No authentication or user interaction is required, and successful requests can expose data reachable only from the gateway's network context.
