Technical details
A directory traversal vulnerability (CWE-22) exists in Esri ArcGIS Server due to improper limitation of pathname parameters. An unauthenticated remote attacker can exploit this by sending specially crafted path parameters in network requests to the server. Successful exploitation allows the attacker to bypass directory restrictions and read sensitive files stored on the underlying Windows or Linux file system. The vulnerability affects all versions of ArcGIS Server up to and including version 12.0. Users are advised to refer to the Esri May 2026 Security Bulletin for patching information.
