CVE-2020-9072

Local privilege escalation via crafted file path

Published Apr 27, 2020 · Updated Aug 4, 2024

Local privilege escalation in Huawei OSD before OSD_uwp_9.0.32.0 allows local users to obtain higher privileges via a crafted file path. Huawei has not published the affected file-handling locus or the incorrect operation performed on that path. Exploitation requires authenticated access to the system and can elevate the attacker's privileges, but no more specific privilege boundary is disclosed.
