EUVD-2025-32573

Comprehensive Technical Analysis of EUVD-2025-32573

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-32573 affects IBM Security Verify Access and IBM Security Verify Access Docker versions 10.0.0.0 through 10.0.9.0 and 11.0.0.0 through 11.0.1.0. This flaw allows a locally authenticated user to escalate their privileges to root due to the execution of certain processes with more privileges than required.

Severity Evaluation:

• Base Score: 9.3 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

The high base score of 9.3 indicates a critical vulnerability. The CVSS vector breakdown shows:

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

This vulnerability is particularly severe because it allows for complete compromise of the affected system, leading to high impacts on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Local Authenticated User: An attacker with local access to the system can exploit this vulnerability.
• Privilege Escalation: The attacker can leverage the flaw to execute processes with elevated privileges, ultimately gaining root access.

Exploitation Methods:

• Exploit Code Execution: The attacker could craft and execute malicious code that takes advantage of the excessive privileges granted to certain processes.
• System Compromise: Once root access is obtained, the attacker can perform various malicious activities, including data exfiltration, system modification, and further propagation within the network.

3. Affected Systems and Software Versions

Affected Products:

• IBM Security Verify Access Appliance:
  • Versions: 10.0.0.0 through 10.0.9.0 IF2
  • Versions: 11.0.0.0 through 11.0.1.0
• IBM Security Verify Access Docker:
  • Versions: 10.0.0.0 through 10.0.9.0 IF2
