CVE-2018-25198Public exploit

Application crash via oversized host-name input

Published Mar 6, 2026 · Updated Mar 6, 2026

Out-of-bounds write in Gaijin.at eToolz 3.4.8.0 allows local attackers to crash the application through oversized host-name input. The Host name / IP address field processes a 255-byte payload without enforcing its destination buffer boundary, causing an out-of-bounds write. Local access is required to supply the crafted field value, and the demonstrated consequence is an application crash rather than code execution.
