Vulnerability Details
According to the official CVE description, this vulnerability exists in the Jenkins Pipeline: Groovy Plugin 2.63 and earlier, specifically within the code found in pom.xml and src/main/java/org/jenkinsci/plugins/workflow/cps/CpsGroovyShell.java. Attackers can exploit this flaw to bypass the sandbox environment and execute arbitrary code on the Jenkins master JVM.
The CVSS score is 9.9, classified as critical, with a vector string indicating that the attack is possible over the network, requires low complexity, and grants attackers high impact on confidentiality, integrity, and availability.
The affected products include the Jenkins Pipeline and Red Hat OpenShift Container Platform version 3.11. The vulnerability was disclosed on March 6, 2019, and is classified under CWE-693.
Technical Analysis
The root cause of CVE-2019-1003030 lies in inadequate sandbox protections in the Jenkins Pipeline: Groovy Plugin, allowing for arbitrary code execution when pipeline scripts are controlled by attackers. The attack vector is network-based, meaning that exploitation can occur remotely. The attack complexity is low, which means that attackers do not require advanced skills to successfully exploit this vulnerability.
Privileges required for exploitation are low, as an attacker does not need elevated permissions to execute the attack. Additionally, user interaction is not required, making this vulnerability particularly dangerous. The impact on confidentiality, integrity, and availability is rated as high, posing significant risks to organizations utilizing Jenkins.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2019-1003030 is substantial. Organizations that do not apply the necessary patches may face severe consequences, including unauthorized access to sensitive systems, data breaches, and potential disruption of services. The blast radius for this vulnerability is extensive due to the widespread use of Jenkins in CI/CD pipelines across various industries.
Given the critical nature of this vulnerability and the potential for exploitation, organizations must act swiftly. The urgency assessment based on the CVSS score and known exploitation indicates that immediate action is essential to protect assets and maintain operational integrity.
