CVE-2019-3786: Cloudfoundry Bosh Backup And Restore

High severity, CVSS 7.1. EPSS: 0.6% chance of exploitation in the next 30 days.

Cloud Foundry BOSH Backup and Restore CLI, all versions prior to 1.5.0, does not check the authenticity of backup scripts in BOSH. A remote authenticated malicious user can modify the metadata file of a Bosh Backup and Restore job to request extra backup files from different jobs upon restore. The exploited hooks in this metadata script were only maintained in the cfcr-etcd-release, so clusters deployed with the BBR job for etcd in this release are vulnerable.

Affected products

• Cloudfoundry Bosh Backup And Restore: before 1.5.0 (fixed in 1.5.0)
