The vulnerability is due to improper handling of Datagram Transport Layer Security (DTLS) fragments by a system running the affected application. The OpenSSL DTLS Fragment Processing Buffer Overflow Vulnerability has been assigned CVE ID CVE-2014-0195. This QID checks for vulnerable version of OpenSSL by extracting openssl version from http response header. If successful, the attacker could perform a man-in-the-middle attack against a targeted system. "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall". "HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall" This QID checks for vulnerable version of OpenSSL by checking the OpenSSL DisplayName value by enumerating the registry keys: QID Detection Logic: Windows (Authenticated) This QID checks for vulnerable version of OpenSSL by running 'openssl version' command. QID Detection Logic: Linux (Authenticated) OpenSSL 3.0.x versions prior to version 3.0.7 OpenSSL has released a high severity security advisory addressing two buffer overrun vulnerabilities (CVE-2022-3602 and CVE-2022-3786) that can be triggered in X.509 certificate verification, specifically in name constraint checking. OpenSSL is a very widely used encryption library, responsible for putting the S in HTTPS, and the padlock in the address bar, for many websites.
