CVE-2019-25547Public exploit

Application crash via oversized user-blocking entry

Published Mar 21, 2026 · Updated Mar 21, 2026

Buffer overflow in NetAware 1.20 User Blocking allows local users to crash the application by entering an oversized filter value. The Add Block dialog accepts a 512-byte website-or-keyword value without enforcing its destination buffer's bounds, and removing the resulting block triggers the overwrite. Exploitation requires access to the local graphical interface and interrupts NetAware without reported data disclosure or modification.
