A new zero-day vulnerability in the Spring Core Java framework called ‘Spring4Shell’ has been publicly disclosed, allowing unauthenticated remote code execution on applications.
Spring is a very popular application framework that allows software developers to quickly and easily develop Java applications with enterprise-level features. These applications can then be deployed on servers, such as Apache Tomcat, as stand-alone packages with all the required dependencies.
Yesterday, a new Spring Cloud Function vulnerability tracked as CVE-2022-22963 was disclosed, with Proof-of-Concept exploits soon to follow.
However, information about a more critical Spring Core remote code execution vulnerability was later circulating on the QQ chat service and a Chinese cybersecurity site.
Today, an exploit for this zero-day vulnerability was briefly leaked and then removed but not before cybersecurity researchers could download the code.
Since then, numerous cybersecurity researchers and security firms have confirmed that the vulnerability is valid and of significant concern.
While this vulnerability at this time is at the developer app design level this does not mean that this vulnerability will not eventually surface at the general user applications level so as always be very cautious in downloading new or enticing applications to install be cautious don’t jump the gun as always ensure before you install any new application ensure you have a full quality backup of your current systems device or devices should anything go seriously wrong you can recover from an infection or compromised system.
