🚨 Windows 10 WebDAV Remote Code Execution Vulnerability Exposes Critical Risk
A newly disclosed Remote Code Execution (RCE) vulnerability affecting Windows 10’s WebDAV client has put millions of systems at risk. This critical flaw allows attackers to remotely execute malicious code by simply tricking a user into connecting to a malicious WebDAV server—often via phishing emails or rogue file links.
🔍 What Is the WebDAV RCE Vulnerability?
WebDAV (Web Distributed Authoring and Versioning) is a protocol built into Windows to support collaborative editing and file management over the web. However, this feature can be weaponized by adversaries. If exploited, the vulnerability can bypass security controls and run arbitrary commands, granting full system access to attackers.
🎯 Affected Systems
- Windows 10 (All supported builds)
- Systems with WebClient service enabled (default on most Windows 10 devices)
⚠️ Why It Matters
- No user interaction beyond opening a malicious link or file
- Can be exploited for lateral movement or initial access
- Attackers can use trusted Windows components (living off the land)
🛡️ How to Protect Your Systems
- Apply Microsoft’s official patch immediately
- Disable the WebClient service if not needed
- Block outbound traffic on port 80/443 to untrusted WebDAV endpoints
- Monitor for suspicious outbound connections and SMB activity
🔐 Final Thoughts
As threat actors continue to exploit native services like WebDAV, it’s crucial for organizations to stay vigilant. Keep your systems patched, educate users on phishing risks, and harden legacy protocols to reduce your attack surface.
