Security readout for executives and security teams
Plain-English summary
This vulnerability can expose Cloud Foundry administrator credentials in deployment errand logs. An authenticated user with BOSH access could read those logs and obtain platform admin credentials, creating a serious risk to confidentiality, integrity, and availability of the Cloud Foundry environment.
Executive priority
Treat this as a high-priority credential exposure issue for affected Cloud Foundry environments. The main business risk is unauthorized platform administration if leaked credentials were viewed before remediation.
Technical view
Cloud Foundry NFS Volume Release 1.2.x before 1.2.5, 1.5.x before 1.5.4, and 1.7.x before 1.7.3 logged the cf admin username and password during the nfsbrokerpush BOSH deploy errand. The issue is privilege-dependent but high impact because leaked credentials are platform-admin credentials.
Likely exposure
Exposure is limited to Cloud Foundry deployments using the affected NFS Volume Release versions where authenticated users can access BOSH and the relevant errand logs.
Exploitation context
The CVE record does not indicate known active exploitation, and it is not listed as KEV in the provided bundle. Abuse requires authenticated BOSH access and access to logs from the NFS volume deploy errand.
Researcher notes
The weakness is sensitive credential disclosure through operational logs, not unauthenticated remote code execution. The main validation focus is version inventory, errand execution history, log accessibility, and whether exposed administrator credentials remain valid.
Mitigation direction
- Upgrade NFS Volume Release to 1.2.5, 1.5.4, 1.7.3, or later supported versions.
- Review Cloud Foundry vendor guidance before making operational changes.
- Rotate cf admin credentials if affected errand logs may have been accessible.
- Restrict BOSH access to administrators with a clear operational need.
- Limit retention and access for deployment errand logs containing sensitive data.
Validation and detection
- Inventory Cloud Foundry NFS Volume Release versions across all foundations.
- Identify whether affected nfsbrokerpush deploy errands ran in the environment.
- Review access controls for BOSH and deployment errand logs.
- Check whether exposed cf admin credentials were rotated after affected errands.
- Confirm upgraded releases no longer log cf admin credentials.
