CVE-2025-6807: Marvell QConvergeConsole Path Traversal

CVE-2025-6807 Overview

CVE-2025-6807 is a directory traversal vulnerability affecting Marvell QConvergeConsole that allows remote attackers to disclose sensitive information without authentication. The flaw exists within the implementation of the getDriverTmpPath method, where improper validation of user-supplied paths enables attackers to read arbitrary files on the system.

Critical Impact

Remote unauthenticated attackers can exploit this vulnerability to access sensitive files in the context of SYSTEM, potentially exposing credentials, configuration data, and other critical information.

Affected Products

• Marvell QConvergeConsole (all versions prior to patch)

Technical Details for CVE-2025-6807

Vulnerability Analysis

This directory traversal vulnerability (CWE-22) exists in the getDriverTmpPath method of Marvell QConvergeConsole. The vulnerability allows remote attackers to bypass intended path restrictions and access files outside the designated directory structure. Since no authentication is required to exploit this flaw, any attacker with network access to the QConvergeConsole interface can potentially read sensitive system files.

The vulnerability is particularly severe because exploitation occurs in the context of SYSTEM privileges, meaning attackers can potentially access highly sensitive files including Windows SAM database contents, application credentials, configuration files containing sensitive data, and other protected system resources.

Root Cause

The root cause of CVE-2025-6807 is the lack of proper validation of user-supplied path parameters before they are used in file operations. The getDriverTmpPath method fails to sanitize input for directory traversal sequences (such as ../ or ..\), allowing attackers to escape the intended directory and access arbitrary locations on the file system.

Attack Vector

The attack can be executed remotely over the network without requiring any form of authentication. An attacker would craft a malicious request to the QConvergeConsole service containing directory traversal sequences in the path parameter. When processed by the getDriverTmpPath method, these sequences allow the attacker to navigate outside the expected directory and read files from arbitrary locations.

The vulnerability requires no user interaction and can be exploited against any exposed QConvergeConsole instance. Successful exploitation results in information disclosure, potentially revealing sensitive system configurations, credentials, or other confidential data that could be leveraged for further attacks.

Detection Methods for CVE-2025-6807

Indicators of Compromise

• Unusual file access patterns in QConvergeConsole logs showing path traversal sequences (../, ..\, or URL-encoded variants)
• Requests to the getDriverTmpPath method containing unexpected path characters or directory references
• Evidence of sensitive file access attempts targeting system directories or configuration files
• Network traffic to QConvergeConsole service from unexpected sources

Detection Strategies

• Monitor network traffic for requests to QConvergeConsole containing directory traversal patterns such as ../, ..\, %2e%2e%2f, or %2e%2e/
• Implement file integrity monitoring for sensitive system files and directories
• Deploy intrusion detection rules to identify path traversal attempts in HTTP/HTTPS requests
• Review QConvergeConsole application logs for anomalous file path requests

Monitoring Recommendations

• Enable verbose logging for the QConvergeConsole service to capture all file access attempts
• Configure SIEM alerts for directory traversal patterns in application and web server logs
• Monitor for unusual outbound data transfers that may indicate successful information exfiltration
• Implement network segmentation monitoring to detect lateral movement following potential exploitation

How to Mitigate CVE-2025-6807

Immediate Actions Required

• Restrict network access to QConvergeConsole to trusted administrative networks only
• Implement firewall rules to block external access to the QConvergeConsole management interface
• Review system logs for evidence of prior exploitation attempts
• Consider temporarily disabling QConvergeConsole if not immediately required until a patch is available

Patch Information

Consult the Zero Day Initiative Advisory ZDI-25-463 for the latest patch information and vendor response details. Monitor Marvell's official security communications for patch availability and apply updates as soon as they are released.

Workarounds

• Implement network-level access controls to restrict QConvergeConsole access to authorized administrator workstations only
• Deploy a web application firewall (WAF) with rules to block directory traversal attempts in request parameters
• Use network segmentation to isolate systems running QConvergeConsole from untrusted networks
• Enable host-based intrusion prevention to detect and block file access attempts outside authorized directories

# Example firewall rule to restrict access to QConvergeConsole (adjust port as needed)
# Windows Firewall - Allow only specific admin subnet
netsh advfirewall firewall add rule name="Restrict QConvergeConsole" dir=in action=block protocol=tcp localport=8080
netsh advfirewall firewall add rule name="Allow QConvergeConsole Admin" dir=in action=allow protocol=tcp localport=8080 remoteip=10.0.1.0/24
