<p class="MsoNormal">CISA and its partners, through the <a href="https://www.cisa.gov/jcdc">
Joint Cyber Defense Collaborative</a>, are tracking and responding to active, widespread exploitation of a critical remote code execution vulnerability (CVE-2021-44228) affecting Apache Log4j software library versions 2.0-beta9 to 2.14.1. Log4j is very broadly
used in a variety of consumer and enterprise services, websites, and applications—as well as in operational technology products—to log security and performance information. An unauthenticated remote actor could exploit this vulnerability to take control of
an affected system.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In response, CISA has created a webpage, <a href="https://cisa.gov/uscert/apache-log4j-vulnerability-guidance">
Apache Log4j Vulnerability Guidance</a>, and <span style="color:#24292F;background:white">
is actively maintaining a </span><a href="https://github.com/cisagov/log4j-affected-db"><span style="background:white">community-sourced GitHub repository</span></a><span style="color:#24292F;background:white"> of publicly available information and vendor-supplied
advisories regarding the Log4j vulnerability. CISA will continually update both the webpage and the GitHub repository</span>.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">CISA urges organizations to review its <a href="https://cisa.gov/uscert/apache-log4j-vulnerability-guidance">
Apache Log4j Vulnerability Guidance</a> webpage and upgrade to Log4j version 2.15.0, or apply the appropriate vendor recommended mitigations immediately.
