Description Preview
This CVE identifies a path traversal (CWE-22) flaw in ArcGIS Server's admin API used for service thumbnails. In ArcGIS Server versions 11.3 and below, a remote authenticated attacker with administrative privileges can craft requests to traverse the server’s file system and read files outside the designated directory. There is no impact to data integrity or service availability from the vulnerability itself, but there is a potential high confidentiality impact due to exposure of sensitive files. The advisory maps to CVSS v3.1: Network attack, low complexity, requiring high privileges, no user interaction, with a base score of 4.9 (Medium) and a confidentiality impact of high. A security update patch is available from Esri to address this issue.
Overview
ArcGIS Server versions 11.3 and earlier contain a directory traversal vulnerability in the admin API responsible for generating service thumbnails. An authenticated administrator can abuse this flaw to navigate the server’s file system and access files outside the permitted directory, potentially exposing sensitive information. While the vulnerability does not alter data or disrupt availability, its primary risk is leakage of confidential data. The issue is categorized as CWE-22 Path Traversal and is mapped to CAPEC-126. Mitigation is expected to be provided via vendor patch, with ongoing guidance to apply updates promptly and restrict admin access.
Remediation
- Apply the ArcGIS Server Security Update 2025 Update 1 patch from Esri as soon as possible. After patching, restart the ArcGIS Server service and verify the patch is active.
- If patch deployment is not feasible immediately, implement compensating controls: restrict admin API access (especially endpoints related to service thumbnails) to trusted admin networks or IPs; enforce TLS and strong authentication for admin accounts; disable or limit access to the admin API for thumbnails if possible; rotate admin credentials and monitor admin activity logs for suspicious requests.
- After patching or applying mitigations, perform validation to confirm the vulnerability is mitigated (e.g., verify patch version, review access patterns, and conduct targeted testing if able).
- Plan for an upgrade to a fixed release version beyond 11.3, per Esri guidance, to reduce the risk of reoccurrence.
