Log4j/Log4Shell One Year Later: Endemic Vulnerability Indeed
On December 9, 2021, Apache upended the cybersecurity industry by publishing a zero-day vulnerability (CVE-2021-44228) for its ubiquitous Log4j logging utility. Dubbed Log4Shell, the remote code execution flaw (CVSS score:10) allows an attacker to take control of a connected device and run malicious code, access sensitive data or alter its configuration. Because Logj4 is free and easy-to-use, it’s embedded (often deeply) in Java applications used by IT and OT platforms worldwide.
