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 · unedited
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Marvell QConvergeConsole 5.5.0.64. Authentication is not required to exploit this vulnerability. The specific flaw exists within the getFileUploadBytes method of the FlashValidatorServiceImpl 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 disclose stored credentials, leading to further compromise. Was ZDI-CAN-10499.

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 confidence

This is an unauthenticated path traversal vulnerability in Marvell QConvergeConsole 5.5.0.64. The getFileUploadBytes method in FlashValidatorServiceImpl class lacks proper validation of user-supplied paths before file operations, allowing remote attackers to read arbitrary files on the system including stored credentials.

MitigationApply vendor patch when available. As an interim control, deploy WAF rules to block path traversal patterns (../, ..\) in request parameters, and restrict network access to the QConvergeConsole interface.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Marvell QConvergeConsole is installed
    Check for QConvergeConsole web interface by accessing the application URL (commonly port 8443 or 8080). Look for the QConvergeConsole login page or check running services on the system that match QConvergeConsole ports.
    Affected if The application is accessible on the network and presents a QConvergeConsole login interface.
  2. Determine the installed QConvergeConsole version
    Log into the QConvergeConsole admin interface and navigate to the About or System Information section to view the version number. Alternatively, check the installation directory for version information in configuration files or the application itself.
    Affected if The version displayed is less than 5.5.00.73 (for example, 5.5.0.64 or any version in the 5.5.0.x range before 5.5.00.73).
  3. Verify the FlashValidatorServiceImpl endpoint is exposed
    Attempt to access or probe the FlashValidatorServiceImpl service endpoint. This is typically exposed via the web interface under paths related to flash validation or file upload functionality. Check web server logs or application mappings for this service path.
    Affected if The FlashValidatorServiceImpl endpoint is accessible without authentication and accepts file-related requests.
  4. Confirm the system is reachable over the network
    Verify that the QConvergeConsole web interface is bound to a network-accessible IP address (not localhost only) and that firewall rules allow access to the management ports from untrusted networks.
    Affected if The QConvergeConsole management interface is reachable from networks that should not have access.

A user is affected if Marvell QConvergeConsole is running with a version lower than 5.5.00.73 and the FlashValidatorServiceImpl endpoint is network-accessible, allowing unauthenticated path traversal attacks to read arbitrary files.
