Automated description summarized from trusted sources.

CVE-2023-52271 describes a vulnerability found in the `wsftprm.sys` kernel driver, version 2.0.0.0, within Topaz Antifraud software. This flaw permits attackers with low privileges to terminate any Protected Process Light (PPL) process. The vulnerability operates through an IOCTL (Input/Output Control) call, allowing a low-privileged user to make arbitrary calls to kernel functions that can kill processes on the system. This capability can be exploited to bypass anti-malware protections, such as those offered by Microsoft Defender.
