CVE-2022-28877

Local privilege escalation via protected file deletion

Published Jul 21, 2022 · Updated Aug 3, 2024

Local privilege escalation in F-Secure and WithSecure Windows endpoint protection products allows local users to delete arbitrary system files. The affected products fail to preserve file protections during deletion, letting an already executing process remove protected files; the vendor has not disclosed the responsible component or file-operation path. Successful exploitation requires prior code-execution rights on the victim machine and yields local privilege escalation through targeted file deletion.
