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.
A zero-day vulnerability involving remote code execution in Log4j 2, given the descriptor "Log4Shell" (CVE-2021-44228), was found and reported to Apache by Alibaba on November 24, 2021, and published in a tweet on December 9, 2021. [12] Affected services include Cloudflare, iCloud, Minecraft: Java Edition, [42] Steam, Tencent QQ, and Twitter.
Source code from almost 6,000 GitHub repositories was leaked, and the 4chan user said it was "part one" of a much larger release. [ 198 ] 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 ...

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 ...
A remote code execution vulnerability affecting certain versions of Spring Framework was published in April 2022 under CVE-2022-22965. It was given the name Spring4Shell in reference to the recent Log4Shell vulnerability, both having similar proofs-of-concept in which attackers could on vulnerable machines, gain shell access [ 130 ] or even ...
A Java logging framework is a computer data logging package for the Java platform. This article covers general purpose logging frameworks. Logging refers to the recording of activity by an application and is a common issue for development teams. Logging frameworks ease and standardize the process of logging for the Java platform.
Functional exploit code is available, and works in most situations where the vulnerability is present. 0.95 High (H) The vulnerability can be exploited by automated code, including mobile code (such as a worm or virus). 1.0 Not Defined (ND) This is a signal to ignore this score. 1.0
