CVE-2025-6793: Marvell QConvergeConsole Path Traversal

CVE-2025-6793 Overview

CVE-2025-6793 is a critical directory traversal vulnerability affecting Marvell QConvergeConsole. This vulnerability allows remote attackers to delete arbitrary files and disclose sensitive information on affected installations without requiring authentication.

The specific flaw exists within the QLogicDownloadImpl class, where the issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to delete files and disclose information in the context of SYSTEM. This vulnerability was tracked as ZDI-CAN-24912 by the Zero Day Initiative.

Critical Impact

Unauthenticated remote attackers can delete arbitrary files and access sensitive information with SYSTEM-level privileges, potentially leading to complete system compromise or denial of service.

Technical Details for CVE-2025-6793

Vulnerability Analysis

This vulnerability is classified as CWE-22 (Path Traversal), representing a critical failure in input validation within the Marvell QConvergeConsole application. The QLogicDownloadImpl class accepts user-supplied path parameters that are used directly in file system operations without proper sanitization.

The vulnerability is exploitable over the network without any form of authentication, making it particularly dangerous for systems exposed to untrusted networks. The attack can be initiated with low complexity, as no special conditions or user interaction are required for successful exploitation.

When exploited, the vulnerability enables two distinct attack outcomes: arbitrary file deletion and information disclosure. The ability to delete files in the context of SYSTEM privileges could allow attackers to remove critical system files, security configurations, or audit logs. Information disclosure capabilities could expose sensitive credentials, configuration data, or other confidential information stored on the affected system.

Root Cause

The root cause of this vulnerability lies in improper input validation within the QLogicDownloadImpl class. The application fails to properly validate and sanitize user-supplied path parameters before using them in file operations. This allows attackers to inject directory traversal sequences (such as ../) to escape the intended directory and access or manipulate files anywhere on the file system.

The lack of authentication requirements for accessing the vulnerable functionality compounds the severity, as any network-connected attacker can exploit this flaw without needing valid credentials.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft malicious requests containing directory traversal sequences to target the vulnerable QLogicDownloadImpl class. By manipulating the path parameter, the attacker can:

1. Navigate outside the intended application directory using sequences like ../../../
2. Target arbitrary files on the system for deletion or disclosure
3. Execute these operations with SYSTEM privileges, bypassing normal access controls

The vulnerability is particularly concerning because the application runs with elevated privileges, meaning any file accessible by the SYSTEM account can be targeted.

Detection Methods for CVE-2025-6793

Indicators of Compromise

• Unexpected file deletions or modifications in system directories
• Unusual access patterns to the QConvergeConsole service from external IP addresses
• Log entries showing path traversal sequences (e.g., ../, ..\\) in file operation requests
• Missing system files or configuration files that were previously present
• Evidence of unauthorized information access in application logs

Detection Strategies

• Monitor network traffic for HTTP requests containing directory traversal patterns targeting QConvergeConsole endpoints
• Implement web application firewall (WAF) rules to detect and block path traversal attempts
• Configure file integrity monitoring (FIM) on critical system directories to detect unauthorized deletions
• Review QConvergeConsole application logs for anomalous file operation requests
• Deploy endpoint detection rules to identify SYSTEM-level file operations initiated by the QConvergeConsole process

Monitoring Recommendations

• Enable verbose logging on QConvergeConsole to capture all file operation requests
• Configure SIEM rules to alert on directory traversal patterns in web server logs
• Monitor for unusual process behavior from the QConvergeConsole application
• Implement network segmentation to limit exposure of management interfaces
• Set up real-time alerts for file deletion events in sensitive directories

How to Mitigate CVE-2025-6793

Immediate Actions Required

• Restrict network access to QConvergeConsole management interfaces to trusted IP addresses only
• Place QConvergeConsole behind a firewall with strict access controls
• Implement web application firewall rules to block directory traversal attempts
• Consider disabling the QConvergeConsole service if not actively required until a patch is available
• Enable additional logging and monitoring to detect exploitation attempts

Patch Information

No vendor patch information is currently available in the CVE data. Organizations should monitor the Zero Day Initiative Advisory ZDI-25-450 for updates and contact Marvell directly for patch availability and remediation guidance.

Workarounds

• Implement strict network segmentation to isolate QConvergeConsole from untrusted networks
• Deploy a reverse proxy with input validation to filter malicious requests
• Configure access control lists (ACLs) to limit which hosts can communicate with the service
• Use a web application firewall configured to block common path traversal patterns
• If possible, disable external network access to the QConvergeConsole management interface entirely

# Example firewall rule to restrict access to QConvergeConsole
# Only allow access from trusted management network
iptables -A INPUT -p tcp --dport 8080 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
