Executive Summary

CVE-2025-56447 is a vulnerability in TM2 Monitoring v3.04 that allows an attacker to bypass authentication and obtain plaintext administrative credentials. This happens because the system relies only on client-side JavaScript for authentication, which can be bypassed by sending an unauthenticated HTTP GET request to the /security.php endpoint. The server then returns sensitive information including admin and guest passwords in clear text within the HTML response, allowing unauthorized access to administrative features. [4]

Impact Analysis

This vulnerability can have severe impacts as it allows attackers to bypass authentication and gain unauthorized access to administrative functions of TM2 Monitoring. Additionally, attackers can obtain plaintext credentials, compromising the confidentiality of sensitive passwords. This can lead to full control over the system's protected features, potentially resulting in data breaches, system manipulation, or further exploitation. [4]

Detection Guidance

This vulnerability can be detected by sending an unauthenticated HTTP GET request to the endpoint /security.php on the TM2 Monitoring v3.04 system and checking if the response contains plaintext administrative credentials in the HTML form inputs. For example, you can use the following command with curl to test for the vulnerability: curl -s http://<target-ip-or-host>/security.php | grep -E 'pw_admin|pw_guest' If the output shows input fields with plaintext passwords, the system is vulnerable.

Mitigation Strategies

Immediate mitigation steps include restricting access to the /security.php endpoint to trusted users only, such as by implementing network-level access controls or firewall rules. Additionally, avoid exposing TM2 Monitoring v3.04 instances directly to untrusted networks until a vendor patch or update is available. Monitoring and alerting on unexpected access to /security.php can also help detect exploitation attempts. [4]
