CVE-2022-22528

Local privilege escalation via installer PATH entry

Published Feb 9, 2022 · Updated Aug 3, 2024

Uncontrolled search path element in SAP SE SAP Adaptive Server Enterprise 16.0 allows local users to execute malicious Windows binaries via the system PATH. The Windows installer adds an ASE-related directory to the system PATH without preventing a standard user from placing a malicious binary earlier in search resolution. Exploitation requires local standard-user access on Windows and can result in privilege escalation; other ASE binaries are not affected.
