CVE-2023-29351Network attack vector

Privilege escalation via Group Policy link following

Published Jun 13, 2023 · Updated Jan 1, 2025

Link following in Windows Group Policy allows remote authenticated users to gain elevated privileges through crafted policy content. Microsoft identifies improper link resolution before file access but has not disclosed the affected file, function, or incorrect link-handling operation. Exploitation requires existing low privileges and network reachability; the resulting privilege level is not publicly specified.
