CVE-2023-36874Windows Error Reporting — a link followed too trustingly

The Windows Error Reporting Service follows a link where it should have refused, and a local user turns that into higher privileges. Exploit code is public; Microsoft publishes nothing beyond the class of flaw.

YOUR NEXT MOVE

Install the July 2023 Windows update. With exploit code public, an unpatched endpoint turns any user-level foothold into control of the machine.
