Log4Shell (CVE-2021-44228) is a zero-day vulnerability reported in November 2021 in Log4j, a popular Java logging framework, involving arbitrary code execution. [2] [3] The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021.
Log4j is one of several Java logging frameworks. Gülcü has since created SLF4J, Reload4j, [4] and Logback [5] [better source needed] which are alternatives to Log4j. [6] The Apache Log4j team developed Log4j 2 [7] in response to the problems of Log4j 1.2, 1.3, java.util.logging and Logback, addressing issues which appeared in those frameworks ...
Criminals and nation states are already trying to exploit the vulnerability According to Microsoft’s threat intelligence team , the majority of the attacks related to the Log4j vulnerability ...
November and December: On November 24, Chen Zhaojun of Alibaba's Cloud Security Team reported a zero-day vulnerability (later dubbed Log4Shell) involving the use of arbitrary code execution in the ubiquitous Java logging framework software Log4j.
On its own, an arbitrary code execution exploit will give the attacker the same privileges as the target process that is vulnerable. [11] For example, if exploiting a flaw in a web browser, an attacker could act as the user, performing actions such as modifying personal computer files or accessing banking information, but would not be able to perform system-level actions (unless the user in ...
The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
Simple Logging Facade for Java (SLF4J) provides a Java logging API by means of a simple facade pattern.The underlying logging backend is determined at runtime by adding the desired binding to the classpath and may be the standard Sun Java logging package java.util.logging, [2] Log4j, Reload4j, Logback [3] or tinylog.
An exploit is the delivery mechanism that takes advantage of the vulnerability to penetrate the target's systems, for such purposes as disrupting operations, installing malware, or exfiltrating data. [6] Researchers Lillian Ablon and Andy Bogart write that "little is known about the true extent, use, benefit, and harm of zero-day exploits". [7]
