CVE-2023-5739

Local privilege escalation via undisclosed flaw

Published Oct 31, 2023 · Updated Sep 12, 2024

Improper privilege management in HP PC Hardware Diagnostics Windows allows local users with low privileges to gain elevated access. HP has not published the affected component or the operation that mishandles privileges, leaving the code-level mechanism undisclosed. Exploitation requires local access and existing low privileges; success elevates the local user's privileges, but no public source identifies the resulting account or execution context.
