EUVD-2025-203905

Comprehensive Technical Analysis of EUVD-2025-203905

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-203905, also known as CVE-2025-67165, is an Insecure Direct Object Reference (IDOR) in Pagekit CMS version 1.0.18. This vulnerability allows attackers to escalate privileges, potentially leading to unauthorized access to sensitive information, modification of data, and disruption of services.

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 ease of exploitation and the severe impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the attack vector is network-based, attackers can exploit this vulnerability remotely without needing physical access to the system.
• Privilege Escalation: Attackers can leverage the IDOR to gain higher privileges within the CMS, allowing them to perform actions typically restricted to administrators.

Exploitation Methods:

• Direct Object Reference Manipulation: Attackers can manipulate URL parameters or form inputs to access unauthorized resources directly.
• Session Hijacking: By exploiting the IDOR, attackers can hijack user sessions and perform actions on behalf of other users, including administrators.
• Data Exfiltration: Attackers can exfiltrate sensitive data by accessing unauthorized resources, leading to data breaches.

3. Affected Systems and Software Versions

Affected Software:

• Pagekit CMS v1.0.18

Potentially Affected Systems:

• Any system running Pagekit CMS version 1.0.18, including web servers, cloud-based deployments, and on-premises installations.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patch Management: Upgrade to a patched version of Pagekit CMS as soon as it becomes available.
• Access Controls: Implement strict access controls and role-based access management to limit the impact of potential privilege escalation.
• Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities promptly.

Long-Term Strategies:

• Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar vulnerabilities.
• User Education: Educate users on the importance of security best practices and the risks associated with IDOR vulnerabilities.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on potential exploitation attempts.

5. Impact on European Cybersecurity Landscape

The presence of this critical vulnerability in a widely-used CMS like Pagekit can have significant implications for the European cybersecurity landscape:

• Data Breaches: Organizations using Pagekit CMS may face data breaches, leading to the exposure of sensitive information.
• Compliance Issues: Non-compliance with data protection regulations such as GDPR can result in legal and financial penalties.
• Reputation Damage: Organizations may suffer reputational damage due to security incidents, affecting customer trust and business operations.

6. Technical Details for Security Professionals

Vulnerability Details:

• IDOR Mechanism: The vulnerability arises from the lack of proper authorization checks when accessing objects directly via URL parameters or form inputs.
• Exploitation Steps:
  1. Identify the vulnerable endpoints in Pagekit CMS.
  2. Manipulate URL parameters or form inputs to reference unauthorized objects.
  3. Perform actions on behalf of other users, including data access, modification, and deletion.

Detection and Response:

• Log Analysis: Analyze web server logs for unusual access patterns and unauthorized requests.
• Anomaly Detection: Implement anomaly detection mechanisms to identify deviations from normal behavior.
• Incident Response: Develop and maintain an incident response plan to address potential exploitation quickly and effectively.
