CVE-2022-47514Public exploitNetwork attack vector

Authenticated SSRF via external entity expansion

Published Dec 18, 2022 · Updated Apr 17, 2025

XXE injection in XML-RPC.NET before 2.5.0 allows remote authenticated users to trigger server-side requests through pingback.aspx POSTs. The pingback.aspx XML request parser accepts attacker-supplied document type declarations and expands external entities into server-side URL and file accesses. Authentication is required; crafted external DTDs can relay local file contents to an attacker-controlled server.
