2021-12-10 17:58

An excruciating, easily exploited flaw in the ubiquitous Java logging library Apache Log4j could allow unauthenticated remote code execution and complete server takeover - and it's being exploited in the wild.

New #0-day vulnerability tracked under "Log4Shell" and CVE-2021-44228 discovered in Apache Log4j We are observing attacks in our honeypot infrastructure coming from the TOR network.

This problem is going to cause a mini-internet meltdown, experts said, given that Log4j is incorporated into scads of popular frameworks, including Apache Struts2, Apache Solr, Apache Druid and Apache Flink.

It's been assigned the maximum CVSS score of 10, given how relatively easy it is to exploit, attackers' ability to seize control of targeted servers and the ubiquity of Log4j.

The security firm said that affected versions are 2.0 <= Apache log4j <= 2.14.1.

To keep the library from being exploited, it's urgently recommended that Log4j versions are upgraded to log4j-2.15.0-rc1.
