AI description
CVE-2026-24294 is an improper authentication vulnerability found within the Windows SMB Server. This flaw allows an authorized attacker to elevate their privileges locally on an affected system. The issue stems from deficiencies in the SMB Server's authentication procedure, which fails to properly validate authentication credentials or session tokens. To exploit this vulnerability, an attacker must already have local access to the target system, typically with low-level privileges. Once present, they can interact with the SMB Server service using crafted authentication requests to bypass normal privilege restrictions and escalate their access rights, potentially achieving SYSTEM-level control. No user interaction is required for successful exploitation.
- Description
- Improper authentication in Windows SMB Server allows an authorized attacker to elevate privileges locally.

NTLM reflection bypass dropped yesterday. CVE-2026-24294. PoC is public. SYSTEM on Windows Server 2025. You know what's funny? Everyone still acts surprised when a 30-year-old auth protocol gets abused. NTLM has been a dumpster fire since the 90s. Kerberos or bust.
