EUVD-2025-23297

Comprehensive Technical Analysis of EUVD-2025-23297

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability in question, identified as EUVD-2025-23297, affects the Marvell QConvergeConsole software. Specifically, the flaw resides in the compressConfigFiles method, which fails to properly validate user-supplied paths before performing file operations. This oversight allows for directory traversal attacks, leading to information disclosure and denial-of-service (DoS) conditions.

Severity Evaluation: The vulnerability has a CVSS Base Score of 9.4, indicating a critical severity level. The CVSS vector CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:H breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal complexity.
• Privileges Required (PR): None (N) - No authentication is required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• Confidentiality (C): High (H) - There is a high impact on confidentiality.
• Integrity (I): Low (L) - There is a low impact on integrity.
• Availability (A): High (H) - There is a high impact on availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Directory Traversal: An attacker can manipulate the user-supplied path to traverse directories and access files outside the intended directory.
• Information Disclosure: By exploiting the directory traversal vulnerability, an attacker can read sensitive configuration files or other critical data.
• Denial-of-Service (DoS): The attacker can manipulate the file operations to cause the system to crash or become unresponsive, leading to a DoS condition.

Exploitation Methods:

• Crafted Requests: An attacker can send specially crafted requests to the compressConfigFiles method with malicious paths designed to traverse directories.
• Automated Scripts: Attackers can use automated scripts to repeatedly send malicious requests, increasing the likelihood of a successful exploit.

3. Affected Systems and Software Versions

Affected Software:

• Product: Marvell QConvergeConsole
• Version: 5.5.0.78

Vendor:
