CVE-2025-6793 in QConvergeConsole
Summary
by MITRE • 07/07/2025
Marvell QConvergeConsole QLogicDownloadImpl Directory Traversal Arbitrary File Deletion and Information Disclosure Vulnerability. This vulnerability allows remote attackers to delete arbitrary files and disclose sensitive information on affected installations of Marvell QConvergeConsole. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the QLogicDownloadImpl class. 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. Was ZDI-CAN-24912.

This vulnerability represents a critical directory traversal flaw in Marvell QConvergeConsole's QLogicDownloadImpl component that enables remote attackers to perform arbitrary file deletion and information disclosure without authentication requirements. The weakness stems from insufficient input validation mechanisms that fail to properly sanitize user-supplied paths before executing file operations, creating a dangerous attack surface where malicious actors can manipulate file system access patterns. Such vulnerabilities fall under CWE-22 Directory Traversal and are classified as privilege escalation issues when they allow execution in SYSTEM context. The vulnerability was tracked as ZDI-CAN-24912 and demonstrates how inadequate path validation can lead to complete system compromise.
The technical implementation of this flaw occurs within the QLogicDownloadImpl class where user-controllable input is directly processed in file operations without proper sanitization or validation checks. Attackers can construct malicious paths that bypass normal file system restrictions, allowing them to traverse directory structures and target files outside intended boundaries. When combined with the SYSTEM context execution, this vulnerability becomes particularly dangerous as it enables attackers to delete critical system files, overwrite configuration data, or extract sensitive information from system directories. The absence of authentication requirements makes exploitation trivial and increases the attack surface significantly.
Operational impact of this vulnerability extends beyond simple file deletion capabilities to include comprehensive information disclosure that can expose system internals, configuration details, and potentially sensitive data stored in accessible locations. Attackers leveraging this vulnerability can gain insights into system architecture, network configurations, and potentially extract credentials or other confidential materials. The SYSTEM context execution means that impacts can be catastrophic, potentially leading to complete system compromise, service disruption, and unauthorized access to enterprise resources. This vulnerability directly maps to ATT&CK technique T1059 Command and Scripting Interpreter and T1070 Indicator Removal on Host, as attackers could delete evidence of their activities while gaining deeper system access.
Mitigation strategies should focus on implementing proper input validation and path sanitization mechanisms within the QLogicDownloadImpl class to prevent malicious path manipulation. Organizations must ensure that all user-supplied inputs undergo rigorous validation before being used in file operations, implementing whitelisting approaches where possible. Network segmentation and access controls should be enforced to limit exposure of vulnerable components, while regular security assessments should verify proper input handling throughout the application stack. System administrators should also implement monitoring solutions to detect anomalous file deletion patterns and unauthorized access attempts that could indicate exploitation of this vulnerability. Regular patch management processes must be established to address similar issues in vendor software components, as this represents a common class of vulnerability that affects many enterprise applications.
