CVE-2015-8103: jenkins: Remote code execution vulnerability due to unsafe deserialization in Jenkins remoting (SECURITY-218)

Severity: Critical

CVSS Score: 9.8

The Jenkins CLI subsystem in Jenkins before 1.638 and LTS before 1.625.2 allows remote attackers to execute arbitrary code via a crafted serialized Java object, related to a problematic webapps/ROOT/WEB-INF/lib/commons-collections-*.jar file and the "Groovy variant in 'ysoserial'".
