CVE-2020-15642
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 · uneditedThis vulnerability allows remote attackers to execute arbitrary code on affected installations of installations of Marvell QConvergeConsole 5.5.0.64. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the isHPSmartComponent method of the GWTTestServiceImpl class. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-10501.
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 confidenceCommand injection vulnerability in Marvell QConvergeConsole 5.5.0.64 in the isHPSmartComponent method of GWTTestServiceImpl class. The flaw lacks proper validation of user-supplied strings before passing them to a system call, allowing arbitrary code execution as SYSTEM. Authentication can be bypassed enabling unauthenticated attackers to reach the vulnerable code path.

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.
-
Verify Marvell QConvergeConsole is installed and runningCheck if the QConvergeConsole web management interface is accessible on the network or localhost. This is typically accessed via HTTPS on port 8443 or similar. Look for the QConvergeConsole login page or service status.Affected if QConvergeConsole is accessible and responds to requests
-
Identify the installed QConvergeConsole versionLog into the QConvergeConsole web interface and navigate to the About or System Information section to view the software version. Alternatively, check the Windows service 'Marvell QConvergeConsole' via services.msc or check installation directories for version files.Affected if Version is displayed as 5.5.0.64 or any version prior to 5.5.00.73
-
Confirm the vulnerable GWTTestServiceImpl component existsInspect the QConvergeConsole web application files if accessible. Look for the class file GWTTestServiceImpl or its compiled equivalent in the application deployment directory. The vulnerable method isHPSmartComponent should be present in unpatched versions.Affected if The GWTTestServiceImpl class with isHPSmartComponent method is present and the version is below 5.5.00.73
-
Check if the management interface is exposed to untrusted networksReview network firewall rules or access control lists to determine if the QConvergeConsole web port (typically 8443) is reachable from untrusted or external networks. Since authentication can be bypassed, external exposure increases risk.Affected if The management interface is exposed to untrusted networks and the version is below 5.5.00.73
The environment is affected if Marvell QConvergeConsole version 5.5.0.64 or any version prior to 5.5.00.73 is installed and the management interface is accessible, regardless of authentication status due to the authentication bypass vulnerability.

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 data5.5.00.73
Apply vendor patch when available; if no patch exists, restrict network access to the management interface and implement robust input validation on the isHPSmartComponent method to prevent command injection.
