Jenkins is a free and open-source automation server that facilitates the continuous integration and delivery of software projects, addressing challenges in build and deployment automation. It powers millions of builds and pipelines worldwide, providing software development teams with a reliable means to automate the entire software delivery process, from code to deployment. Jenkins is used by organizations of all sizes to speed up the software delivery cycle and increase the productivity and efficiency of their development teams.

CVE-2020-2103 is a vulnerability that was detected in Jenkins 2.218 and earlier, LTS 2.204.1 and earlier. The vulnerability was caused by the exposure of session identifiers on a user's detail object in the whoAmI diagnostic page. Attackers who exploit this vulnerability can harvest session identifiers and use them to hijack the user's session, gain access to sensitive information, or perform unauthorized actions on the application servers.

When this vulnerability is exploited, it can lead to a wide range of negative consequences. Attackers can access sensitive data, such as source code, production databases, and system configurations. They can also change user privileges and access controls, perform fraudulent transactions, and leverage this vulnerability to launch more severe attacks such as ransomware. Since Jenkins is commonly used for software development and delivery, an attacker with access to the system could potentially compromise entire software delivery pipelines.
