CVE-2019-19452Public exploit

SYSTEM privilege escalation via unchecked IOCTL copy

Published Feb 21, 2020 · Updated Aug 5, 2024

Stack overflow in Patriot Viper RGB 1.1 and earlier allows local users to execute code as NT AUTHORITY\SYSTEM via a crafted IOCTL. The 0x80102040 handler passes an attacker-controlled source and length to memmove without checking the fixed stack destination, and the function lacks a stack security cookie. Any low-integrity process that can open the Msio device can trigger the overwrite; successful exploitation grants SYSTEM privileges, although the published x64 exploit requires adaptation beyond Windows 7 SP1.
