A SQL injection vulnerability in ArcGIS Server allows an EDIT operation to modify column properties in a manner that could lead to SQL injection when performed by a remote authenticated user requiring elevated, non‑administrative privileges. Exploitation is restricted to users with advanced application‑specific permissions, indicating high privileges are required. Successful exploitation would have a high impact on integrity and confidentiality, with no impact on availability.

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.
