CVE-2018-1000068: An improper input validation vulnerability exists in Jenkins versions 2.106 and earlier, and LTS 2.89.3 and...

Security readout for executives and security teams

This Jenkins issue could let an attacker read plugin resource files that Jenkins intended to keep inaccessible. The condition is specific: affected Jenkins versions with the Jenkins home directory on a case-insensitive file system. Business urgency depends on whether legacy Jenkins still exists in that configuration. Exposure is most likely in older Jenkins controllers at or below 2.106, or LTS at or below 2.89.3, where JENKINS_HOME resides on a case-insensitive file system. Current or upgraded Jenkins instances are not confirmed affected by the supplied sources. Address during legacy Jenkins risk cleanup unless affected internet-facing Jenkins controllers are found. If an exposed controller matches the vulnerable version and filesystem condition, prioritize remediation promptly because CI systems often hold sensitive build and credential context. Mitigation focus: Review Jenkins SECURITY-717 for vendor remediation guidance.; Upgrade affected Jenkins instances to a release outside the affected version range.; Prioritize controllers using case-insensitive file systems for JENKINS_HOME..
