AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Path traversal in Altium Enterprise Server and Altium 365 allows authenticated users to read arbitrary files, potentially exposing credentials.

Vulnerability

A path traversal vulnerability exists in the Projects Service download endpoint of Altium Enterprise Server and Altium 365. An authenticated user can provide a crafted path parameter to bypass validation checks, enabling the reading of arbitrary files or entire directories from the server's filesystem [1].

Exploitation

An authenticated user can exploit this vulnerability by supplying a specially crafted path parameter to the Projects Service download endpoint. This crafted parameter bypasses existing validation, allowing the attacker to specify arbitrary file paths on the server that they wish to read [1].

Impact

Successful exploitation allows an attacker to read sensitive files from the server's filesystem, including service configuration files and credential material. This information can be used to facilitate further compromise. In multi-tenant Altium 365 deployments, the readable configuration could expose credentials shared across services [1].

Mitigation

Altium Enterprise Server is fixed in version 8.1.1. The issue has been remediated at the service level for Altium 365 cloud deployments, meaning no customer action is required for Altium 365 [1].
