Technical details
This is a stored (persistent) cross-site scripting (XSS) vulnerability in Esri Portal for ArcGIS affecting versions 11.5 and earlier. The vulnerability allows an authenticated, privileged user to inject malicious JavaScript that is stored in the application and executed in the browsers of other users who access the compromised content. The attack requires high-level privileges and user interaction (victim accessing the malicious content), but succeeds remotely over the network. A successful exploit enables attackers to steal session tokens, perform actions on behalf of victims, or capture sensitive information. Esri advises upgrading to the latest long-term support release or applying available security patches.
