Auvik Networks, ConnectWise, Datto, Kaseya, Liongard, N-able, NinjaOne and Pax8 are among the MSP software companies and SaaS marketplace providers to issue statements about the widespread Log4j vulnerability (aka CVE-2021-44228), also known as Log4Shell.
The Log4j vulnerability allows unauthenticated remote code execution (RCE) on any Java application running a vulnerable version of Apache’s Log4j 2, BlackPoint Cyber told MSSP Alert.
In a statement, the Cybersecurity and Infrastructure Security Agency (CISA) on December 11, 2021 called the Log4j vulnerability a "severe risk" and offered this four-step guidance to patch Log4j and mitigate potential Log4Shell cyberattacks.
Still, the worldwide Log4j software cleanup could take months, SC Media reported, because thousands of third-party software products run the code.
Amid that backdrop, many MSP software companies have been checking their code for potential exposure to the vulnerability. For MSPs, the status updates and associated vendor guidance could help the overall managed services industry to avoid potential supply chain attacks related to Log4j.
