CVE-2018-25268Public exploit

Application crash via scan-field buffer overflow

Published Apr 22, 2026 · Updated Apr 22, 2026

Out-of-bounds write in LizardSystems LanSpy 2.0.1.159 allows local users to overwrite EIP and crash the application via the scan field. The scan field accepts 688 padding bytes followed by four attacker-controlled bytes without enforcing its buffer boundary, causing the controlled bytes to replace EIP. Local access to the Windows GUI is required; the public artifact demonstrates a crash only, and arbitrary code execution has not been demonstrated.
