Comprehensive Technical Analysis of EUVD-2025-5339

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-5339 pertains to Seacms versions 13.3 and earlier, which are susceptible to SQL Injection in the admin_zyk.php file. The CVSS (Common Vulnerability Scoring System) Base Score of 9.8 indicates a critical severity level. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability can be exploited remotely over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
• Privileges Required (PR): None (N) - No special privileges are needed to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required for the attack to succeed.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• Confidentiality (C): High (H) - The vulnerability allows for unauthorized access to sensitive information.
• Integrity (I): High (H) - The vulnerability allows for unauthorized modification of data.
• Availability (A): High (H) - The vulnerability allows for disruption of services.

Given the high scores in Confidentiality, Integrity, and Availability, this vulnerability poses a significant risk to affected systems.

2. Potential Attack Vectors and Exploitation Methods

SQL Injection is a common attack vector where malicious SQL statements are inserted into an entry field for execution. In this case, the admin_zyk.php file in Seacms versions 13.3 and earlier is vulnerable. Potential exploitation methods include:

• Direct SQL Injection: An attacker could input malicious SQL queries directly into the vulnerable parameter, potentially extracting sensitive data, modifying database contents, or executing administrative operations.
• Blind SQL Injection: If the application does not return error messages, an attacker could use blind SQL injection techniques to infer database structure and data.
• Automated Tools: Attackers may use automated tools to scan for and exploit SQL injection vulnerabilities, making the attack process more efficient and scalable.

3. Affected Systems and Software Versions

The vulnerability affects Seacms versions 13.3 and earlier. Any system running these versions of Seacms is at risk. This includes web servers hosting Seacms applications, particularly those with administrative access to the admin_zyk.php file.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Patch Management: Upgrade to a patched version of Seacms that addresses this vulnerability. If a patch is not available, consider applying a vendor-provided workaround.
• Input Validation: Implement robust input validation and sanitization to prevent malicious SQL queries from being executed.
• Parameterized Queries: Use parameterized queries or prepared statements to ensure that SQL code is separated from data.
• Web Application Firewalls (WAF): Deploy WAFs to detect and block SQL injection attempts.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address similar issues proactively.
• Least Privilege Principle: Ensure that database accounts used by the application have the minimum necessary privileges.

5. Impact on European Cybersecurity Landscape

The presence of such a critical vulnerability in widely-used software like Seacms underscores the importance of vigilant cybersecurity practices. Organizations across Europe using Seacms must prioritize patching and securing their systems to prevent potential data breaches and service disruptions. The high CVSS score indicates that this vulnerability could be exploited to cause significant damage, affecting the confidentiality, integrity, and availability of data.

6. Technical Details for Security Professionals

For security professionals, the following technical details are pertinent:

• Vulnerable File: admin_zyk.php
• Exploitation Method: SQL Injection via improperly sanitized user input.
• References:
  • GitHub Repository
  • NVD Entry
