Esri vulnerabilities and threats

There is an improper access control issue in ArcGIS Server versions 11.3 and below on Windows and Linux which, under unique circumstances, could allow a remote, low‑privileged authenticated attacker to access secure services published to a standalone (unfederated) ArcGIS Server instance. Successful exploitation results in unauthorized access to protected services outside the attacker’s originally assigned authorization boundary, constituting a scope change. If exploited, this issue would have a high impact on confidentiality, a low impact on integrity, and no impact on the availability of the software.

There is a reflected Cross‑Site Scripting (XSS) vulnerability in Esri Portal for ArcGIS versions 11.1 and 11.2 that may allow a remote, authenticated attacker with low‑privileged access to create a crafted link which, when clicked, could potentially execute arbitrary JavaScript code in the victim’s browser. Exploitation is limited to the same browser execution context and does not result in a change of security scope beyond the affected user session.

There is a difficult‑to‑exploit improper authentication issue in the Home application for Esri Portal for ArcGIS versions 11.2 and below on Windows and Linux, and ArcGIS Enterprise versions 11.1 and below on Kubernetes, which under unique circumstances could allow a remote, authenticated attacker with low‑privileged access to compromise the confidentiality, integrity, and availability of the software. Successful exploitation allows the attacker to cross an authentication and authorization boundary beyond their originally assigned access, resulting in a scope change.
