CVE-2025-8426
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMarvell QConvergeConsole compressConfigFiles Directory Traversal Information Disclosure and Denial-of-Service Vulnerability. This vulnerability allows remote attackers to disclose sensitive information or to create a denial-of-service condition on affected installations of Marvell QConvergeConsole. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the compressConfigFiles method. 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 disclose sensitive information or to create a denial-of-service condition on the system. Was ZDI-CAN-24915.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a directory traversal vulnerability in Marvell QConvergeConsole's compressConfigFiles method. The flaw allows remote unauthenticated attackers to manipulate file paths using traversal sequences (../) to access arbitrary files on the system, leading to sensitive information disclosure or denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Marvell QConvergeConsole is installedLocate the QConvergeConsole application installation directory or running service on the system. This is typically found in the installation path where Marvell management software resides.Affected if The application is present and running on the system.
-
Determine the installed versionUse the application's built-in version display mechanism, check the installation directory for version files, or query the web interface for version information. Compare your found version against the affected version 5.5.0.85.Affected if The installed version matches exactly 5.5.0.85.
-
Verify the compressConfigFiles functionality is accessibleIdentify whether the compressConfigFiles method or its associated web endpoint is exposed and accessible. This method is part of the application's file handling functionality.Affected if The compressConfigFiles method is accessible without authentication.
-
Check network exposure of the management interfaceDetermine if the QConvergeConsole web interface is reachable from network locations. This vulnerability can be exploited by remote unauthenticated attackers.Affected if The management interface is exposed to untrusted networks.
You are affected if Marvell QConvergeConsole version 5.5.0.85 is installed and the compressConfigFiles method is accessible to unauthenticated remote users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict path validation in the compressConfigFiles method to ensure user-supplied paths are confined to allowed directories; sanitize or reject path traversal sequences. Apply vendor patches when available.
