Local privilege escalation via object memory mishandling
Published Mar 12, 2020 · Updated Aug 4, 2024
Object-handling error in Microsoft Windows Search Indexer allows local users with low privileges to elevate privileges through local access. The indexer mishandles objects in memory, but Microsoft has not disclosed the affected operation or the attacker-controlled object state. Exploitation requires local low-privilege access and grants elevated rights; no remote attack path or user interaction is reported.
