Description

PassFab Excel Password Recovery 8.3.1 contains a structured exception handling buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying a malicious payload in the registration code field. Attackers can craft a buffer overflow payload with a pop-pop-ret gadget and shellcode that triggers code execution when pasted into the Licensed E-mail and Registration Code field during the registration process.
