CVE-2025-6793

Comprehensive Technical Analysis of CVE-2025-6793

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-6793 CVSS Score: 9.4

The vulnerability in Marvell QConvergeConsole, specifically within the QLogicDownloadImpl class, allows for directory traversal, arbitrary file deletion, and information disclosure. The lack of proper validation of user-supplied paths in file operations is the root cause. This vulnerability is severe due to the following factors:

• No Authentication Required: Attackers can exploit this vulnerability without needing any authentication.
• High Impact: The ability to delete arbitrary files and disclose sensitive information can lead to significant data loss and compromise of system integrity.
• System Context: The vulnerability operates in the context of SYSTEM, meaning it has high privileges on the affected system.

Given the CVSS score of 9.4, this vulnerability is considered critical and requires immediate attention.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: Attackers can remotely exploit this vulnerability by sending crafted requests to the affected system.
• Directory Traversal: By manipulating the user-supplied path, attackers can traverse directories and access or delete files outside the intended directory.

Exploitation Methods:

• Path Manipulation: Attackers can supply specially crafted paths (e.g., using "../" sequences) to traverse directories and access or delete files.
• Information Disclosure: By reading sensitive files, attackers can gain unauthorized access to confidential information.
• File Deletion: Attackers can delete critical system files, leading to denial of service or system instability.
