CVE-2012-5389Network attack vector

Remote application crash via NULL pointer dereference

Published Jan 23, 2020 · Updated Aug 6, 2024

NULL pointer dereference in PowerTCP WebServer for ActiveX 1.9.2 and earlier allows remote attackers to cause an application crash via a crafted HTTP request. Processing a crafted HTTP request reaches a null pointer dereference in the WebServer component and crashes the application. No authentication is required, and the consequence is a denial of service limited to interruption of the affected application.
