CVE-2025-24039
📋 TL;DR
This CVE describes an elevation of privilege vulnerability in Visual Studio Code where an attacker could execute arbitrary code with higher privileges than intended. It affects users running Visual Studio Code on Windows systems. The vulnerability stems from improper handling of DLL loading paths (CWE-427).
💻 Affected Systems
- Visual Studio Code
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could gain SYSTEM-level privileges on the affected Windows machine, potentially leading to complete system compromise, data theft, or installation of persistent malware.
Likely Case
Local authenticated attackers could escalate privileges to install software, modify system settings, or access restricted files and directories they shouldn't normally access.
If Mitigated
With proper user account controls and limited privileges, impact would be contained to the user's context rather than full system compromise.
🎯 Exploit Status
Exploitation requires local access and some user interaction or specific conditions. No public exploits are currently available.
