CVE-2018-25307Public exploit

Local code execution via crafted registration key

Published Apr 29, 2026 · Updated Apr 29, 2026

Buffer overflow in Flexense's SysGauge Pro 4.6.12 allows local users to execute arbitrary code through a crafted registration unlock key. The Register function copies an overlong Unlock Key value without checking its size, overwriting the structured exception handler so execution reaches embedded shellcode. Local access to the registration interface is required, and resulting code runs with the application's privileges.
