A few hours ago, a 0-day exploit in the popular Java logging library log4j2 was
discovered that results in Remote Code Execution (RCE) by logging a certain
string.

Given how ubiquitous this library is, the impact of the exploit (full
server control), and how easy it is to exploit, the impact of this
vulnerability is quite severe. We're calling it "Log4Shell" for short
(CVE-2021-44228 just isn't as memorable).

The 0-day was tweeted
<https://twitter.com/P0rZ9/status/1468949890571337731> along
with a POC posted on GitHub
<https://github.com/tangxiaofeng7/apache-log4j-poc>. Since this
vulnerability is still very new, there isn't a CVE to track it yet. This
has been published as CVE-2021-44228
<https://www.randori.com/blog/cve-2021-44228/> now.
