Comprehensive Technical Analysis of EUVD-2025-205282

1. Vulnerability Assessment and Severity Evaluation

The EUVD entry EUVD-2025-205282 describes a Server-Side Request Forgery (SSRF) vulnerability in the 6Storage Rentals plugin for WordPress. The vulnerability allows an attacker to induce the server-side application to make HTTP requests to an arbitrary domain chosen by the attacker. This can lead to unauthorized access to internal systems, services, and data.

Severity Evaluation:

• Base Score: 9.1 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

The CVSS score of 9.1 indicates a critical vulnerability due to the high impact on confidentiality and integrity, with a low attack complexity and no requirement for user interaction or privileges.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthorized Access: An attacker can exploit the SSRF vulnerability to access internal services and resources that are not exposed to the public internet.
• Data Exfiltration: By manipulating the server to make requests to internal services, an attacker can exfiltrate sensitive data.
• Service Disruption: The attacker can use the SSRF vulnerability to disrupt internal services by sending malicious requests.

Exploitation Methods:

• Crafted HTTP Requests: An attacker can send specially crafted HTTP requests to the vulnerable server, inducing it to make requests to internal or external services.
• URL Manipulation: By manipulating URLs in the requests, an attacker can target specific internal services or resources.

3. Affected Systems and Software Versions

Affected Software:

• 6Storage Rentals Plugin for WordPress
• Versions: From n/a through <= 2.19.9
