CVE-2022-45398 An CSRF vulnerability in Jenkins Cluster Statistics Plugin 0.4.6 and earlier allows attackers to delete recorded Jenkins Cluster Statistics.

CSRF is a type of Hijacking where an attacker tricks another user into performing an action on the victim’s behalf by tricking the victim into clicking a link, opening a particular attachment, etc. In this case, an attacker sends a request to change the configuration of the plugin (e.g. change the URL that is recorded in the plugin), and the victim may be an administrator, which results in the vulnerability. This can be mitigated by following best practices such as changing the password for the Jenkins user in a secure way, restricting access to the Jenkins server, and hardening the Jenkins setup to reduce the likelihood of an attacker exploiting this vulnerability. The Jenkins team releases new versions of its software on a regular basis with new bug fixes and enhancements. As partOf the effort to ensure a continuous high quality of service, the team maintains close monitoring of reported issues and fixed bugs. However, due to the nature of the software development process, some issues get fixed in a new version of Jenkins but are not reported until later. If you suspect you are running a vulnerable version, do NOT ignore this issue; report it to thejenkinsci team.

What is the Jenkins CI?

Jenkins CI is a continuous integration platform. It allows developers to automate the build, test, and deployment of software. It's a popular choice for software projects that need to be built and tested in a short amount of time or have many different developers working on them. Jenkins CI provides many features including automatic builds, unit testing, generating HTML websites from the source code, and integrating with Git repositories.

Possible Impact of CSRF

The main impact of this vulnerability is that an attacker can execute actions on the victim’s behalf by taking advantage of this vulnerability. Additionally, the attacker can use CSRF to gain access to confidential data or perform privileged actions on behalf of the victim, such as changing their password. There are many ways in which an attacker might exploit this vulnerability. For example, if a user is logged out of Jenkins and they visit a malicious webpage while they are logged out, the attacker may be able to exploit the CSRF vulnerability by persuading them to change their password when they click on a button. On WordPress blogs, it may be possible for an attacker to get a user’s administrator password using CSRF if they trick the user into visiting a malicious website and then force them to log in with the admin account. This could allow an attacker to take over your blog without your knowledge!

What makes Jenkins insecure?

CSRF vulnerability is a common attack vector for Jenkins users. In this case, an attacker sends a request to change the configuration of the plugin (e.g. change the URL that is recorded in the plugin), and the victim may be an administrator, which results in the vulnerability. This can be mitigated by following best practices such as changing the password for the Jenkins user in a secure way, restricting access to the Jenkins server, and hardening the Jenkins setup to reduce the likelihood of an attacker exploiting this vulnerability.
