Description

An XML External Entity (XXE) injection vulnerability exists in ETQ Reliance on the CG (legacy) platform within the `/resources/sessions/sso` endpoint. The SAML authentication handler processes XML input without disabling external entity resolution, allowing crafted SAML responses to invoke external entity references. This could enable attackers to retrieve sensitive files or perform server-side request forgery (SSRF). The issue was addressed by disabling external entity processing for the affected XML parser in versions SE.2025.1 and 2025.1.2.

Affected products

• ETQ Reliance CG (legacy): before SE.2025.1; before 2025.1.2 — fixed in 2025.1.2, SE.2025.1

How to fix

Upgrade to a fixed version: ETQ Reliance CG (legacy) 2025.1.2, SE.2025.1. Check the vendor advisory for mitigations.
