Security readout for executives and security teams
Plain-English summary
This flaw affects Cloud Foundry NFS Volume Service. An authenticated space developer could influence LDAP filtering during service instance creation, potentially causing service denial or enabling dictionary-style credential probing. It requires authenticated access and high attack complexity, but the potential confidentiality and integrity impact makes it a high-priority platform issue.
Executive priority
Treat as high priority for Cloud Foundry platforms that expose NFS Volume Service to developers. Prioritize version verification and upgrades, but do not frame this as confirmed active exploitation based on the supplied evidence.
Technical view
CVE-2019-11277 is LDAP injection in Cloud Foundry NFS Volume Service 1.7.x before 1.7.11 and 2.x before 2.3.0. The CVSS 3.0 score is 8.4 with network attack vector, low privileges, no user interaction, high complexity, and scope change. CWE-90 applies.
Likely exposure
Exposure is likely limited to Cloud Foundry environments using the affected NFS Volume Service releases, especially where space developers can create service instances. The bundle also lists CF Deployment as affected, but the concrete vulnerable component is the NFS volume service.
Exploitation context
The source describes a remote authenticated malicious space developer. No KEV listing is present, and the supplied sources do not state active exploitation. Reported outcomes are denial of service or dictionary attack facilitation, not unauthenticated takeover.
Researcher notes
The issue is grounded in LDAP filter injection during service instance creation. Useful validation focuses on version state, broker configuration, LDAP integration, and developer permissions. The public bundle does not provide patch internals or safe reproduction details.
Mitigation direction
- Upgrade NFS Volume Service 1.7.x to 1.7.11 or later.
- Upgrade NFS Volume Service 2.x to 2.3.0 or later.
- Review Cloud Foundry vendor guidance for deployment-specific remediation.
- Limit service instance creation rights to trusted space developers.
- Monitor LDAP and service broker activity for abnormal creation patterns.
Validation and detection
- Inventory Cloud Foundry foundations using NFS Volume Service.
- Confirm deployed NFS Volume Service release versions.
- Check whether space developers can create affected service instances.
- Review broker and LDAP logs for unusual failed lookup patterns.
- Verify upgraded foundations report fixed NFS Volume Service versions.
