CVE-2023-6891

Local code execution via unchecked drag-drop DLL

Published Dec 17, 2023 · Updated Aug 2, 2024

Uncontrolled search path in PeaZip 9.4.0 for Windows allows local users to execute code through dragdropfilesdll.dll loading. The application does not authenticate the Windows drag-and-drop DLL against a trusted SHA-256 value before loading it. Exploitation requires local access sufficient to place a replacement DLL in a searched location, after which PeaZip runs attacker-controlled code in its process.
