CVE-2018-8725

Local code execution via internal-channel buffer overflow

Published Jan 11, 2021 · Updated Jul 9, 2026

Buffer overflow in K7TSMngr.exe in K7 Computing K7AntiVirus Premium 15.01.00.53 allows local users to execute arbitrary code. The executable incorrectly processes specially crafted input received through an internal communication channel, overflowing a buffer; public sources do not identify the exact field or copy operation. A local low-privileged user must reach that channel, and successful exploitation runs code in the security product's privileged process context.
