EUVD-2024-53137

Comprehensive Technical Analysis of EUVD-2024-53137

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2024-53137, also known as CVE-2024-56404, is an insecure direct object reference (IDOR) vulnerability in One Identity Identity Manager versions 9.x before 9.3. This vulnerability allows for privilege escalation, which can be exploited by attackers to gain unauthorized access to sensitive information or perform actions that should be restricted to higher-privileged users.

Severity Evaluation:

• Base Score: 9.9 (Critical)
• Base Score Version: 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

The CVSS score of 9.9 indicates a critical vulnerability due to the following factors:

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

This high score reflects the significant impact on confidentiality, integrity, and availability, as well as the ease of exploitation.

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.
• Low Complexity: The low complexity of the attack means that minimal effort is required to exploit the vulnerability.
• Low Privileges Required: Attackers need only low-level privileges to initiate the attack, making it easier to exploit.

Exploitation Methods:

• Direct Object Reference Manipulation: Attackers can manipulate direct object references to access unauthorized data or functions.
• Privilege Escalation: By exploiting the IDOR vulnerability, attackers can escalate their privileges to perform actions reserved for higher-privileged users.

3. Affected Systems and Software Versions

Affected Systems:

• One Identity Identity Manager: Versions 9.0.0 to 9.2.x
• Deployment Type: On-Premise installations only

Unaffected Systems:

• One Identity Identity Manager: Version 9.3 and above
• Cloud-Based Installations: Not affected

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade Software: Upgrade to One Identity Identity Manager version 9.3 or later, which includes the necessary patches to mitigate this vulnerability.
• Access Controls: Implement strict access controls and monitor for unusual activity.
• Network Segmentation: Segment the network to limit the scope of potential attacks.

Long-Term Strategies:

• Regular Patching: Ensure that all software is regularly updated and patched.
• Security Audits: Conduct regular security audits to identify and mitigate vulnerabilities.
• User Training: Educate users on the importance of security best practices and the risks associated with IDOR vulnerabilities.

5. Impact on European Cybersecurity Landscape

The critical nature of this vulnerability poses a significant risk to organizations using One Identity Identity Manager within the European Union. Given the EU's stringent data protection regulations, such as GDPR, a successful exploitation could result in severe legal and financial repercussions. Organizations must prioritize patching and mitigation efforts to avoid potential data breaches and compliance issues.
