Webinar: Log4Shell Explained
In response to Apache Log4Shell vulnerability gaining worldwide attention, Cyberint's Research team shares the latest insights and recommendations on how to stay protected.
How to Keep Your Data Secure in Light of Apache Log4j Vulnerabilities
In quick succession in December, The Apache Software Foundation released information on two critical vulnerabilities in its Log4j Java-based library. The first vulnerability CVE-2021-44228, also known as Log4Shell or LogJam, was reported as an unauthenticated remote code execution (RCE) vulnerability. By exploiting how the library logs error messages, it could lead to a complete system takeover.
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?
The DHS is inviting hackers to break into its systems, but there are rules of engagement
The United States Department of Homeland Security (DHS) is inviting security researchers to uncover vulnerabilities and hack into its systems, in an attempt to better protect itself from malicious attacks.
Global outbreak of Log4Shell
Log4Shell is a high severity vulnerability (CVE-2021-44228) impacting Apache Log4j versions 2.0 to 2.14.1. It was discovered by Chen Zhaojun of Alibaba Cloud Security Team and disclosed via the project´s GitHub repository on December 9, 2021.
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.
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.
Sideloading: "a cybercriminal's best friend"
Sideloading is the installation of software from a third party rather than an approved source, for example applications that are not available from official vendors or app stores. This hack is creating yet another valuable opportunity for cybercriminals.
Understanding the Log4j Log4Shell Vulnerability
A zero-day threat is creating waves through the cybersecurity industry more than any other in years. On Thursday, December 9, security researchers published a proof-of-concept exploit code for CVE-2021-44228, a remote code execution vulnerability in Log4j, a Java logging library used in a significant number of internet applications. In the week since its discovery businesses worldwide are frantically trying to identify and mitigate the exploit, while security pros and experts are desperately attempting to release patches and guide organizations as new information becomes known.
