CVE-2021-28472: Visual Studio Code Maven for Java Extension Remote Code Execution Vulnerability

Visual Studio Code Maven for Java Extension Remote Code Execution Vulnerability

HighCVSS 7.8Not KEV-listedUpdated
Glexia's TakeAutomated analysishigh

Security readout for executives and security teams

Plain-English summary

This is a high-severity remote code execution issue in Microsoft's Maven for Java extension for Visual Studio Code. The main business risk is compromise of developer workstations where the extension is installed and used. The source bundle shows user interaction is required and does not show known active exploitation.

Executive priority

Treat this as a high-priority developer workstation risk, especially in engineering environments with access to source code or deployment credentials. It is important, but the provided evidence does not support emergency active-exploitation language.

Technical view

CVE-2021-28472 affects Microsoft Visual Studio Code - Maven for Java Extension. CVSS 3.1 is 7.8 with local attack vector, low complexity, no privileges required, user interaction required, unchanged scope, and high confidentiality, integrity, and availability impact. The bundle does not provide CWE detail or exploit mechanics.

Likely exposure

Exposure is likely limited to developer endpoints or build-related workstations with the Visual Studio Code Maven for Java extension installed. This is not described as an internet-facing server vulnerability in the provided sources.

Exploitation context

The CVSS vector indicates a local, user-assisted attack path with no privileges required. KEV status is false, and the provided sources do not state active exploitation or public exploit availability.

Researcher notes

The public bundle is sparse: no CWE, no root-cause detail, and no exploit description are provided. Analysis should stay anchored to the CVSS vector, affected product entry, KEV false status, and Microsoft advisory reference.

Mitigation direction

  • Review Microsoft's MSRC advisory for the official fix or vendor-directed action.
  • Update the Maven for Java extension through trusted Visual Studio Code extension channels.
  • Prioritize developer systems that handle sensitive source code, credentials, or production access.
  • Disable or remove the extension where it is unnecessary or cannot be updated promptly.

Validation and detection

  • Inventory VS Code extensions on developer endpoints for Maven for Java usage.
  • Confirm installed extension versions against Microsoft's advisory guidance.
  • Verify update controls can reach trusted extension sources.
  • Check endpoint telemetry for suspicious activity around affected developer machines.
