Technical details
A missing authentication vulnerability exists in Esri Portal for ArcGIS versions 12.0 and prior, allowing unauthenticated remote attackers to access specific protected resources. The vulnerability stems from insufficient authentication checks on certain API endpoints or resources that should require user authentication. No user-generated content is directly compromised, but system-level resources become accessible without credentials. The attack requires only network connectivity and no user interaction. Esri recommends upgrading to the latest long-term support release to remediate this issue.
