Patch to Fix Critical OpenSLL Vulnerability Will Be Available on November 1, 2022

There is an alert given to the healthcare and public health industry concerning a critical vulnerability identified in the OpenSSL software library. Most operating systems and apps use OpenSLL, an open-source cryptographic library, for employing Transport Layer Security for safe Web communications, which include linking to websites and web apps.

The OpenSSL project team states the vulnerability impacts OpenSSL versions 3.0 to 3.0.6, however, doesn’t impact LibreSSL or OpenSSL 1.1.1.
There is no disclosure concerning information about the actual nature of the vulnerability yet to control the chance of exploitation. More details regarding the vulnerability are likely to be available together with the patch, which is going to be used in OpenSLL version 3.0.7. Presently, there is no CVE code assigned yet.

Although the OpenSLL project team has announced the vulnerabilities previously, critical vulnerabilities are unusual. A critical vulnerability impacts typical configurations and is most likely to be exploited. In 2014, OpenSLL found a critical vulnerability referred to as Heartbleed, which can be exploited to acquire encryption keys or passwords. The vulnerability made it possible for anybody online to view the memory of systems that utilized unsecured OpenSLL versions. Threat actors quickly exploited the bug to spy on communications, steal information directly from services and end users, and double as services and end users. Since OpenSLL is so greatly utilized, the intensity of this kind of vulnerability is huge. Patching each case where OpenSSL was used can take a long time.

The Health Sector Cybersecurity Coordination Center (HC3) discussed in a cybersecurity warning the likely attempt of threat actors to greatly exploit the vulnerability and states that exploitation could start soon following the release of the patch. Cybercriminal and nation-state threat actors are likely to quickly commence reverse engineering the patch the moment it is introduced to find out the technical information of the vulnerability to enable the creation of an exploit.

HC3 is telling all HPH sector companies to look at this vulnerability as the top priority and make sure the patch is employed quickly. To ensure that happens, it is going to be required to find all cases where OpenSSL is employed. OpenSSL Project team states the patch is going to be available on November 1, 2022 from 13:00 to 1700 UTC.

On November 1, 2022, the OpenSSL Project affirmed that the two vulnerabilities are high-severity instead of critical, however quick patching is still highly recommended to go into remote code execution.
