CVE-2018-25265Public exploit

Local code execution via scan buffer overflow

Published Apr 22, 2026 · Updated Apr 22, 2026

Buffer overflow in the scan section of LizardSystems LanSpy 2.0.1.159 allows local users to execute arbitrary code via crafted input. Oversized scan data corrupts the SEH chain, redirects a controlled jump to an egghunter, and locates attacker-supplied shellcode in memory. Local access to the application is required, and successful exploitation runs code in the security context of the LanSpy process.
