There is an privilege escalation vulnerability in organization-specific logins in Esri Portal for ArcGIS versions 10.9 and below that may allow a remote, authenticated attacker who is able to intercept and modify a SAML assertion to impersonate another account (XML Signature Wrapping Attack). In addition patching, Esri also strongly recommends as best practice for SAML assertions to be signed and encrypted.
The product does not verify, or incorrectly verifies, the cryptographic signature for data.
