Last updated on: 2026-11-10

Assigner: VulnCheck

Description
Mediary Scout before 2026.11.05 contains a server-side request forgery vulnerability that allows any authenticated user, including non-owner accounts, to set an arbitrary PanSou base URL via savePanSouBaseUrlAction without role checks. Attackers can trigger probePanSou() to send server-side POST requests to internal hosts and use distinct error responses as an oracle for internal host and port discovery.

Executive Summary

CVE-2026-125359 is a Server-Side Request Forgery (SSRF) vulnerability in Mediary Scout versions before 2026.11.05. It allows any authenticated user, including non-owner accounts, to set an arbitrary PanSou base URL without proper role checks. Attackers can trigger probePanSou() to send server-side POST requests to internal hosts and use error responses to discover internal hosts and open ports.

Detection Guidance

To detect this SSRF vulnerability in Mediary Scout, monitor for unauthorized POST requests to internal hosts triggered by the probePanSou() function. Check logs for requests to arbitrary URLs from the savePanSouBaseUrlAction endpoint. Look for distinct error responses indicating internal host or port discovery attempts.

Impact Analysis

This vulnerability enables attackers to map your internal network by sending requests to internal hosts and ports. It could lead to unauthorized access to sensitive internal services or data if combined with other vulnerabilities. The impact includes potential data breaches, service disruption, or further exploitation of internal systems.

Compliance Impact

This SSRF vulnerability could lead to unauthorized access to internal systems, potentially violating data protection requirements under GDPR (e.g., unauthorized data access) or HIPAA (e.g., exposure of protected health information). Organizations may face compliance violations if internal systems are compromised.

Mitigation Strategies

Upgrade Mediary Scout to version 2026.11.05 or later. Ensure the fix restricting PanSou base URL modifications to site owners is applied. Review logs for prior exploit attempts and block unauthorized access to the savePanSouBaseUrlAction function.
