EUVD-2025-25753

Comprehensive Technical Analysis of EUVD-2025-25753

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-25753 is an authentication bypass issue affecting the Unified Privileged Access Management (PAM) solution by Securden. This vulnerability allows an unauthenticated attacker to control administrator backup functions, potentially leading to the compromise of sensitive information such as passwords, secrets, and application session tokens.

Severity Evaluation:

• CVSS Base Score: 9.8 (Critical)
• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

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

• Attack Vector (AV:N): The vulnerability can be exploited over the network.
• Attack Complexity (AC:L): The attack requires low complexity.
• Privileges Required (PR:N): No privileges are required to exploit the vulnerability.
• User Interaction (UI:N): No user interaction is required.
• Scope (S:U): The vulnerability affects the same security scope.
• Confidentiality (C:H), Integrity (I:H), Availability (A:H): The vulnerability has a high impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the CVSS vector, the vulnerability can be exploited remotely over the network.
• Unauthenticated Access: The attacker does not need any prior authentication to exploit the vulnerability.

Exploitation Methods:

• Backup Function Manipulation: The attacker can manipulate the backup functions of the Unified PAM, potentially extracting sensitive data.
• Data Exfiltration: By controlling the backup functions, the attacker can exfiltrate passwords, secrets, and session tokens.
• Privilege Escalation: The attacker can use the compromised data to escalate privileges within the affected system.

3. Affected Systems and Software Versions

Affected Product:

• Unified PAM by Securden

Affected Versions:

• Versions 9.0.* through 11.3.1

Vendor:

• Securden
