CVE-2022-43402 presents a critical vulnerability that allows attackers to bypass sandbox protections in Jenkins Pipeline: Groovy Plugin versions 2802.v5ea_628154b_c2 and earlier. This vulnerability allows those with permissions to define and run sandboxed scripts to execute arbitrary code within the Jenkins controller JVM. With a CVSS score of 9.9, this vulnerability poses a significant risk to organizations that utilize Jenkins for their CI/CD processes.
The exploitation of this vulnerability can lead to unauthorized access and control over the Jenkins environment, potentially allowing attackers to manipulate builds, steal sensitive information, or deploy malicious code. Given the critical nature of this vulnerability and its high impact on confidentiality, integrity, and availability, organizations must take immediate action.
Currently, there are no known public exploits for this vulnerability, but the potential for exploitation remains high due to the nature of the vulnerability. Organizations should prioritize patching Jenkins Pipeline to mitigate the risks associated with this vulnerability.
Organizations should prioritize patching immediately to secure their Jenkins environments and prevent potential exploitation.
Vulnerability Details
The official description of this vulnerability states: 'A sandbox bypass vulnerability involving various casts performed implicitly by the Groovy language runtime in Jenkins Pipeline: Groovy Plugin 2802.v5ea_628154b_c2 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.' This vulnerability is classified as critical due to its CVSS score of 9.9, indicating a high severity level.
Affected products include Jenkins Pipeline: Groovy Plugin versions prior to 2802.v5ea_628154b_c2. The vulnerability was published on October 19, 2022, and has been marked as modified in status.
Technical Analysis
The root cause of CVE-2022-43402 lies in the Groovy language runtime, which performs various implicit casts that can be exploited to bypass the sandbox restrictions. The attack vector is network-based, and the attack complexity is low, meaning that minimal effort is required for an attacker to exploit this vulnerability.
Privileges required for exploitation are low, allowing users with basic permissions to potentially execute malicious scripts. User interaction is not required, which further increases the risk associated with this vulnerability. Confidentiality, integrity, and availability impacts are all rated as high, emphasizing the critical need for immediate remediation.
Risk & Impact Analysis
Organizations deploying Jenkins Pipeline without prompt remediation are at significant risk of exploitation. The potential blast radius is considerable, as successful exploitation can lead to full control of the Jenkins environment, allowing attackers to manipulate builds and access sensitive data.
With the vulnerability classified as critical and possessing a high CVSS score, organizations should assess their exposure to this vulnerability and prioritize it for immediate remediation in their patch management cycle.
