CVE-2025-40656

Comprehensive Technical Analysis of CVE-2025-40656

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-40656 Description: A SQL injection vulnerability has been identified in DM Corporative CMS. This vulnerability allows an attacker to execute arbitrary SQL commands through the cod parameter in the /administer/node-selection/data.asp endpoint. CVSS Score: 9.8

Severity Evaluation: The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for complete compromise of the database, leading to unauthorized access, data manipulation, and potential data exfiltration. The vulnerability can be exploited remotely without requiring any special privileges, making it highly dangerous.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker can send crafted HTTP requests to the vulnerable endpoint, injecting malicious SQL commands.
• Automated Scanning: Attackers may use automated tools to scan for vulnerable instances of DM Corporative CMS and exploit the SQL injection vulnerability.

Exploitation Methods:

• SQL Injection: By manipulating the cod parameter, an attacker can inject SQL commands to retrieve sensitive data, modify database entries, or delete critical information.
• Data Exfiltration: Attackers can extract entire databases, including user credentials, personal information, and other sensitive data.
• Privilege Escalation: If the database contains administrative credentials or other sensitive information, attackers can use this to escalate privileges within the system.
