EUVD-2025-13576

Comprehensive Technical Analysis of EUVD-2025-13576

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability EUVD-2025-13576 pertains to an SQL injection flaw in TCMAN's GIM v11. This vulnerability allows an unauthenticated attacker to inject malicious SQL statements into the ‘Sender’ and ‘email’ parameters of the ‘createNotificationAndroid’ endpoint. This can result in the unauthorized retrieval, modification, and deletion of all information within the database.

Severity Evaluation: The Base Score of 9.3, as per CVSS 4.0, indicates a critical severity level. The 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 highlights 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 Change (SC): None (N)
• Secondary Impact (SI): None (N)
• Secondary Availability (SA): None (N)

This vulnerability poses a significant risk due to its high impact on confidentiality, integrity, and availability, combined with the ease of exploitation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: The attacker does not need to be authenticated to exploit this vulnerability.
• Network Access: The attack can be conducted over the network, making it accessible to remote attackers.

Exploitation Methods:

• SQL Injection: The attacker can craft SQL statements and inject them into the ‘Sender’ and ‘email’ parameters of the ‘createNotificationAndroid’ endpoint. This can be done using standard SQL injection techniques such as:
  • Union-based SQL Injection: Combining the results of two SELECT statements.
  • Error-based SQL Injection: Triggering database errors to extract information.
  • Blind SQL Injection: Using conditional statements to infer database information.

3. Affected Systems and Software Versions

Affected Systems:

• Product: TCMAN's GIM
• Version: v11

Software Versions:

• All instances of TCMAN's GIM v11 are affected by this vulnerability.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Apply the latest security patches provided by TCMAN.
• Input Validation: Implement strict input validation and sanitization for all user inputs, especially for the ‘Sender’ and ‘email’ parameters.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Web Application Firewall (WAF): Deploy a WAF to detect and block SQL injection attempts.

Long-term Mitigation:

• Regular Security Audits: Conduct regular security audits and vulnerability assessments.
