Comprehensive Technical Analysis of EUVD-2025-11498

1. Vulnerability Assessment and Severity Evaluation

The EUVD entry EUVD-2025-11498 describes a SQL Injection vulnerability in the TP-Link M7650 4G LTE Mobile Wi-Fi Router, specifically in Firmware Version 1.0.7 Build 170623 Rel.1022n. This vulnerability allows an unauthenticated attacker to inject malicious SQL statements via the username and password fields.

Severity Evaluation:

• Base Score: 9.8 (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:H

The CVSS score of 9.8 indicates a critical vulnerability due to the following factors:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This high score reflects the potential for significant impact on confidentiality, integrity, and availability of the affected system.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: The attacker can exploit the vulnerability without needing any credentials.
• Network Access: The attack can be carried out over the network, making it accessible from remote locations.

Exploitation Methods:

• SQL Injection: The attacker can inject malicious SQL queries through the username and password fields.
• Data Exfiltration: By crafting specific SQL queries, the attacker can extract sensitive information from the database.
• Database Manipulation: The attacker can alter, delete, or insert data into the database, compromising its integrity.
• Privilege Escalation: If the database is connected to other systems or services, the attacker could potentially escalate privileges and gain further access.

3. Affected Systems and Software Versions

Affected Systems:

• TP-Link M7650 4G LTE Mobile Wi-Fi Router

Affected Software Versions:

• Firmware Version 1.0.7 Build 170623 Rel.1022n
