Unauthenticated remote privilege escalation
Published Jul 12, 2022 · Updated Jul 8, 2025
Elevation of privilege in Microsoft IIS on affected Windows releases allows remote attackers to gain elevated privileges through network requests. Microsoft has not published the vulnerable IIS component or the incorrect operation it performs on attacker-controlled input. Exploitation requires no authentication or user interaction but has high attack complexity; successful attacks compromise confidentiality and integrity without interrupting availability.
