CVE-2025-11837
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 · uneditedAn improper control of generation of code vulnerability has been reported to affect Malware Remover. The remote attackers can then exploit the vulnerability to bypass protection mechanism. We have already fixed the vulnerability in the following version: Malware Remover 6.6.8.20251023 and later
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 · low confidenceA code injection vulnerability in Malware Remover allows remote attackers to improperly control code generation, enabling them to bypass security protections. The vulnerability stems from insufficient validation or sanitization of input that leads to dynamic code execution.

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.
-
Confirm Malware Remover is installedLog into QTS admin interface and navigate to App Center, or use the command line to query installed packages (e.g., qpkg -l or similar Qnap package listing command)Affected if Malware Remover does not appear in the installed applications list
-
Locate the installed version numberIn QTS App Center, click on Malware Remover to view its details and version information; alternatively, check via command line if availableAffected if Unable to retrieve version information from the Qnap system
-
Compare version against affected rangeCheck if the installed version falls within >= 6.6.3 and < 6.6.8.20251023. Note the exact version number displayed in the application details.Affected if The installed version is 6.6.3 or any version up to (but not including) 6.6.8.20251023
A Qnap system running Malware Remover with version 6.6.3 through 6.6.8.20251022 is affected by this code injection vulnerability.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped6.6.8.20251023
Organizations using Malware Remover versions prior to 6.6.8.20251023 should immediately upgrade to the fixed version to prevent remote attackers from exploiting the code injection to bypass protection mechanisms.
Malware Remover 6.6.8.20251023 or later
- Upgrade Malware Remover to version 6.6.8.20251023 or later via the QNAP App Center or System Update interface
- After upgrade, verify the installed version confirms the fix is applied
- Ensure Malware Remover protection features are re-enabled and functioning after the update
