Attack-Flow Graph

Executive Summary

ArcGIS Server contains a directory traversal vulnerability that can be exploited by an unauthenticated attacker. The attacker can send specially crafted path parameters to the server, which allows them to access sensitive files on the system.

Impact Analysis

This vulnerability can have a severe impact as it allows an unauthenticated attacker to access sensitive files on the system. This can lead to the exposure of confidential information, potential data breaches, and compromise of system integrity.

Compliance Impact

The vulnerability allows an unauthenticated attacker to access sensitive files on the system through directory traversal. This unauthorized access to sensitive data could lead to violations of data protection regulations such as GDPR and HIPAA, which require strict controls over access to personal and protected health information.

Therefore, exploitation of this vulnerability could result in non-compliance with these standards due to potential data breaches and unauthorized disclosure of sensitive information.
