CVE-2017-20229

Description

A flaw was found in MAWK. Attackers can exploit a stack-based buffer overflow vulnerability by crafting malicious input that bypasses inadequate boundary checks. This allows them to overwrite memory on the program's call stack, leading to the execution of arbitrary code. Successful exploitation can result in an attacker gaining control over the affected system with the privileges of the MAWK application.
