Exploitation Summary

EIP tracks 1 public exploit for CVE-2020-24972. PoCs published by SpiralBL0CK.

AI-analyzed exploit summary This PoC exploits CVE-2020-24972 by leveraging the Qt platformpluginpath command-line option to load a malicious DLL. The DLL, when loaded by a vulnerable application like Kleopatra, executes arbitrary code via a MessageBox pop-up as a proof of concept.

Description

The Kleopatra component before 3.1.12 (and before 20.07.80) for GnuPG allows remote attackers to execute arbitrary code because openpgp4fpr: URLs are supported without safe handling of command-line options. The Qt platformpluginpath command-line option can be used to load an arbitrary DLL.
