CVE-2024-49049
📋 TL;DR
This vulnerability in Visual Studio Code's Remote Extension allows attackers to escalate privileges when connecting to remote workspaces. It affects users who utilize VS Code's remote development features to connect to untrusted or compromised remote machines. Successful exploitation could allow attackers to execute arbitrary code with elevated permissions on the host system.
💻 Affected Systems
- Visual Studio Code
📦 What is this software?
Remote Ssh by Microsoft
⚠️ Risk & Real-World Impact
Worst Case
An attacker could achieve remote code execution with elevated privileges on the host system, potentially compromising the entire development environment and adjacent systems.
Likely Case
Attackers could execute arbitrary code with the privileges of the VS Code process, potentially accessing sensitive files, credentials, or development artifacts.
If Mitigated
With proper network segmentation and restricted remote workspace access, impact is limited to isolated development environments.
🎯 Exploit Status
Requires attacker to control or compromise a remote workspace that the victim connects to using VS Code Remote extensions
