x are not affected, users are recommended to upgrade to Log4j 2.3.2 (for Java 6), 2.12.4 (for Java 7), or 2.17.1 (for Java 8 and later).Īlso, Microsoft has warned Windows and Azure customers to remain vigilant after observing state-sponsored and cyber-criminal attackers probing systems for the Log4j vulnerability flaw through December. Tracked as CVE-2021-44832, the vulnerability is rated 6.6 in severity on a scale of 10 and impacts all versions of the logging library from 2.0-alpha7 to 2.17.0 with the exception of 2.3.2 and 2.12.4.

On the 28th of December, The Apache Software Foundation (ASF) rolled out fresh patches to contain an arbitrary code execution flaw in Log4j that could be abused by threat actors to run malicious code on affected systems, making it the “fifth security shortcoming” to be discovered in the tool in the span of a month. They said the severity is “high” and gave it a CVSS score of 7.5. Apache said version 2.16 “does not always protect from infinite recursion in lookup evaluation” and explained that it is vulnerable to CVE-2021-45105, a denial of service vulnerability.

On Friday, Apache has released version 2.17.0 of the patch for Log4j after discovering issues with their previous release. The new vulnerability, with a severity score (CVSS) of 9.0 out of 10.0, is again a remote-code execution flaw. If you are using any log4j versions from 2.0 to 2.14.1, you are affected by this vulnerability, so patch now! If you are using Log4j 1.x, you are impacted by this vulnerability only if you are using JMS Appenders.Īccording to Apache’s latest update, there is another vulnerability discovered on Log4j2, tracked as CVE-2021-45046. The high CVSS score hints that the vulnerability should be patched right away. The vulnerability that caused the Equifax data breach in 2017 was similar to the Log4j exposure that came out today, but it was a very innocent vulnerability.Īuthorities have determined the vulnerability’s criticality level (CVSS) as 10 out of 10. Reminding us of the Equifax vulnerability might be good to refresh our memory. It is so critical that it causes different companies to experience security breaches at an unexpected moment. 2- How Critical is a Vulnerability Detected in Log4j?Īlthough the Log4Shell vulnerability, detected by Chen Zhaojun from the Alibaba Cloud security team, does not seem to be fully understood yet, it looks like a vulnerability that will be discussed the most in the coming years. Considering that the number of devices using Java worldwide is in the billions, it is not surprising that Log4j appears in unexpected and unexpected places. Log4j is actively involved in many Java applications by making optional level-based logging. Log4j is a java-based logging library that Ceki Gulcu developed, then transferred to the Apache Software Foundation, and produced by ASF. In this blog post, we would like to share the questions that will come to mind for all segments from different levels of responsibility on the subject, with action-oriented answers.ġ- What is Log4j, When was Log4j Released, What is it Used For, and Why is it so Important? Security professionals are ramping up their efforts to identify the applications running Log4j to patch as threat actors started widespread scanning and exploitation.

The vulnerability, lastly tracked as CVE-2021-44832, is dubbed Log4Shell. We can even see the effect of the Log4j vulnerability in the Google Trends results. In the last 72 hours, the entire cyber security community has focused on the critical vulnerability of Log4j, actively used in millions of systems.
