CVE-2017-1000095
Description
The jenkins-plugin-script-security improperly whitelisted "DefaultGroovyMethods.putAt(Object, String, Object)" and "DefaultGroovyMethods.getAt(Object, String)" which allows attackers to bypass many restrictions and potentially trigger builds or access data they should not have access to. Exploitation of this requires the attacker to have access to the Jenkins instance, and for that Jenkins instance to be hosting other projects as well that the attacker should not have access to.
Statement
This issue affects the versions of jenkins-plugin-script-security as shipped with OpenShift Enterprise 3. However, this flaw is of low impact under the supported scenarios in OpenShift Enterprise 3. A future update may address this issue.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
