Critical vulnerability in log4j, a widely used logging library

Security researchers recently disclosed the vulnerability CVE-2021-44228 in Apache’s log4j, which is a common Java-based library used for logging purposes. Popular projects, such as Struts2, Kafka, and Solr make use of log4j. The vulnerability was announced on Twitter, with a link to a github commit which shows the issue being fixed. Proof-of-concept code was also released to github which shows that the vulnerability is trivial to exploit.

Log4Shell Is the Most Dangerous Exploit Since Shellshock

Earlier today, a serious flaw was discovered in the widely used Java logging library Apache Log4j. The vulnerability, ‘Log4Shell,’ was first identified by users of a popular Minecraft forum and was apparently disclosed to the Apache Foundation by Alibaba Cloud security researchers on Nov. 24, 2021. The vulnerability has the potential to allow unauthenticated remote code execution (RCE) on nearly any machine using Log4j.

Log4j2 Vulnerability "Log4Shell" (CVE-2021-44228)

Apache has released version 2.16.0, which completely removes support for Message Lookups and disables JNDI by default. CrowdStrike has identified a malicious Java class file hosted on infrastructure associated with a nation-state adversary. The Java code is used to download known instances of adversary-specific tooling and is likely to be used in conjunction with the recently disclosed Log4Shell exploit (CVE-2021-44228).

Log4Shell CVE-2021-44228

On December 10th, 2021, the National Vulnerability Database (NVD) published the CVE-2021-44228 documenting a vulnerability in the Apache log4j library Java Naming and Directory Interface (JNDI) lookup feature allowing for remote code execution by an attacker who is able to manipulate log messages. A proof of concept was released on December 9th, 2021, and active scanning and exploitation attempts have increased through the time of the publishing of this brief.

How to Make Your Vulnerability Management Metrics Count

Software development organizations are investing more and more resources in their vulnerability management programs. According to Gartner’s forecast, in 2021 enterprise security spending was expected to break records and grow 12.4% to reach 150.4 billion. But how do organizations know if they’re spending their security resources wisely? The answer can only be found by crunching the numbers.

What is Metasploit?

The Metasploit Framework is a Ruby-based, open-source framework that is used by information security professionals and cybercriminals to find, exploit, and validate system vulnerabilities. The framework consists of various exploitation tools and penetration testing tools. Information security teams most commonly use Metasploit for penetration testing (or “ethical hacking”) to identify and remediate any existing vulnerabilities across an organization’s networks.

Of the nearly 165,000 known CVEs, which ones are putting your company at risk?

There are almost 165,000 known CVEs (Common Vulnerabilities and Exposures) listed in the NIST Database. In October of 2020, the NSA published a list of the 25 CVEs most likely to be exploited by Nation-State attackers in China; Checkpoint software found over 3 million attempts to penetrate networks or steal files using these known vulnerabilities.

Redscan analysis of NIST NVD reveals record number of vulnerabilities in 2021

Our latest analysis of the National Vulnerability Database (NVD) has revealed that 2021 has now officially broken the record for common vulnerabilities and exposures (CVEs) logged by researchers. NIST is the US National Institute of Standards and Technology, and its National Vulnerability Database (NVD) is a repository of Common Vulnerabilities and Exposures (CVEs).

Malicious npm Packages Are After Your Discord Tokens - 17 New Packages Disclosed

The JFrog Security research team continuously monitors popular open source software (OSS) repositories with our automated tooling, and reports any vulnerabilities or malicious packages discovered to repository maintainers and the wider community. Most recently we disclosed 11 malicious packages in the PyPI repository, a discovery that shows attacks are getting more sophisticated in their approach.
