CVE-2022-23170Network attack vector

Unauthenticated file read via SAML XXE

Published Jun 24, 2022 · Updated Sep 16, 2024

XXE in SysAid Okta SSO Integration 22.1.49 through 22.1.63 allows remote attackers to read server files via a crafted SAML POST. The identity-provider endpoint parses attacker-controlled XML and resolves external entities that reference local files or network resources. The endpoint is reachable without authentication; access to sensitive resources also enables SSRF against systems reachable by the server.
