SecurityScorecard Finds Log4j Active Exploitation from Nation State Actors

There's little question that you've already heard about the recently discovered security flaw related to Log4j, a widely used Java library for logging error messages in applications. The vulnerability enables a threat actor to remotely execute commands via remote code execution (RCE) on nearly any machine using Log4j. But it's also important to cut through all of the noise to truly understand the implications of the Log4j and what organizations can do to combat it.

Arctic Wolf Releases Open Source Log4Shell Detection Script

After successful deployment to Arctic Wolf’s customer community of more than 2,300 organizations worldwide, today we are making “Log4Shell Deep Scan” publicly available on GitHub. Log4Shell Deep Scan enables detection of both CVE-2021-45046 and CVE-2021-44228 within nested JAR files, as well as WAR and EAR files.

How Kroll is Handling CVE-2021-44228 (Log4J / Log4Shell)

A critical vulnerability has been recently discovered in the Apache Log4j Java logging library (CVE-2021-44228), a library used in many client and server applications. The Log4j library is commonly included in Java based software including multiple Apache frameworks such as Struts2, Solr, Druid and Fink. The library provides enhanced logging functionality for Java applications and is commonly used in business system development.

LOG4J security vulnerability (Log4Shell)

On Nov. 24th 2021 a severe security vulnerability, called “Log4Shell”, has been reported in the JAVA framework “Log4J” 2.x which is widely used for event logging in JAVA applications worldwide. The vulnerability allows cyber-attackers to execute arbitrary code by injecting it into a logging process implemented in Log4J. The “Log4Shell” vulnerability allows complete server takeover by the attackers.

What has the Log4shell vulnerability taught us about application security?

A week ago, we had no idea what Log4shell was. Today, we have the global developer community coming together to keep itself safe from a vulnerability that ranks the highest in terms of risk. We need technical solutions, but what does it mean for the landscape of application security, and what have we learned from this situation?

Exploiting and Mitigating CVE-2021-44228: Log4j Remote Code Execution (RCE)

A new critical vulnerability has been found in log4j, a widely-used open-source utility used to generate logs inside java applications. The vulnerability CVE-2021-44228, also known as Log4Shell, permits a Remote Code Execution (RCE) allowing the attackers to execute arbitrary code on the host. The log4j utility is popular and used by a huge number of applications and companies, including the famous game Minecraft. It is also used in various Apache frameworks like Struts2, Kafka, Druid, Flink, and many commercial products.
