Comprehensive Technical Analysis of EUVD-2025-13579

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The EUVD entry EUVD-2025-13579 describes a critical SQL injection vulnerability in TCMAN's GIM v11. This vulnerability allows an unauthenticated attacker to inject malicious SQL statements into the 'User' parameter of the 'ValidateUserAndGetData' endpoint, potentially leading to unauthorized access, modification, or deletion of database information.

Severity Evaluation: The vulnerability has a CVSS Base Score of 9.3, which is considered critical. The CVSS vector string CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N indicates the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Authentication (AT): None (N)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Confidentiality Impact (VC): High (H)
• Integrity Impact (VI): High (H)
• Availability Impact (VA): High (H)
• Scope (SC): Not Changed (N)
• Scope Impact (SI): Not Changed (N)
• Scope Availability (SA): Not Changed (N)

This high severity score underscores the critical nature of the vulnerability, which can lead to significant data breaches and system compromises.
