CVE-2025-63218

Comprehensive Technical Analysis of CVE-2025-63218

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-63218 CISA Vulnerability Name: CVE-2025-63218 CVSS Score: 9.8

The vulnerability in Axel Technology WOLF1MS and WOLF2MS devices (firmware versions 0.8.5 to 1.0.3) involves Broken Access Control due to missing authentication on the /cgi-bin/gstFcgi.fcgi endpoint. This flaw allows unauthenticated remote attackers to perform critical administrative actions, including listing user accounts, creating new administrative users, deleting users, and modifying system settings.

Severity Evaluation: The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for full device compromise, the ease of exploitation, and the significant impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit the vulnerability without needing any credentials.
• Remote Exploitation: The vulnerability can be exploited over the network, making it accessible to attackers from anywhere in the world.

Exploitation Methods:

• Direct HTTP Requests: Attackers can send crafted HTTP requests to the /cgi-bin/gstFcgi.fcgi endpoint to perform unauthorized actions.
• Automated Scripts: Malicious actors can use automated scripts to scan for vulnerable devices and exploit them en masse.

3. Affected Systems and Software Versions

Affected Devices:

• Axel Technology WOLF1MS
• Axel Technology WOLF2MS

Affected Firmware Versions:

• 0.8.5 to 1.0.3

Note: Devices running firmware versions outside this range are not affected by this specific vulnerability.
