Windows SMB Client Security Feature Bypass Vulnerability

Incorrect authorization in Windows SMB Client allows an authorized attacker to bypass a security feature locally.

FAQ

What kind of security feature could be bypassed by successfully exploiting this vulnerability?

Successfully exploiting this vulnerability could allow an attacker to bypass network security protections that rely on Fully Qualified Domain Name (FQDN)‑based rules, such as policies that block or allow network connections based on domain names. This could reduce the effectiveness of security features that depend on those domain‑based network controls.
