The vulnerability is related to a design flaw in Jenkins that allows attackers to send arbitrary commands to the Jenkins server. The messages are executed by an agent/controller process that runs on the same machine as the Jenkins server. Therefore, an attacker must first gain control of an agent/controller process on the same machine as the Jenkins server, as well as on any other machines where the Jenkins server may be installed. If the agent/controller process on the machine where the Jenkins server is running accepts commands from any remote IP address, then it can be exploited to send messages to the Jenkins server that will result in arbitrary commands being executed by the server. For example: In order to exploit the vulnerability, the attacker must have access to an agent/controller process on the same machine as the Jenkins server. The attacker must then send a message to the agent/controller process on the same machine as the Jenkins server that contains commands that can be used to exploit the vulnerability. For example: - Configure a Jenkins server with Xpediter installed. - Enable Code Coverage on the codebase. - Install Jenkins and Xpediter. - Configure Code Coverage to run on every push. - Install Jenkins, Xpediter, and plugins. - Configure Xpediter to run on every push. - Install Jenkins and plugins. - Configure Jenkins to run on every push. - Install Xpediter and plugins. - Configure Xpediter to run on every push. - Download Jenkins and Xpediter
Summary
The vulnerability is a design flaw in Jenkins that allows attackers to send arbitrary commands to the Jenkins server. The messages are executed by an agent/controller process that runs on the same machine as the Jenkins server. Therefore, for a successful exploit, an attacker must first gain control of an agent/controller process on the same machine as the Jenkins server, as well as any other machines where the Jenkins server may be installed.
For example: In order to exploit the vulnerability, an attacker must have access to an agent/controller process on the same machine as the Jenkins server. The attacker must then send a message to the agent/controller process on the same machine as the Jenkins server that contains commands that can be used to exploit the vulnerability. For example: - Configure a Jenkins server with Xpediter installed. - Enable Code Coverage on the codebase. - Install Jenkins and Xpediter. - Configure Code Coverage to run on every push. - Install Jenkins, Xpediter, and plugins.
Job Lifecycle and Code Coverage
Code coverage is a metric that measures the degree to which source code of a software application is tested. Code coverage can be measured as either line-coverage or branch-coverage. Line coverage measures how many lines of code are executed while branch coverage measures whether a particular branch in program code was executed at least once, even if some other branches were not executed.
Code coverage is important because it indicates the degree to which tests have been performed and provides insight into where testing efforts need to be focused in order to achieve higher quality software releases. For example, a line-coverage metric of 90 percent means that 90 percent of the source code has been tested by automated tools.
