AnalysisAI
Privilege enforcement failure in Apache Accumulo 2.1.4 and 2.1.5 allows any authenticated low-privileged user - one without system-level permissions - to remotely trigger graceful shutdown of critical cluster services including the manager, tserver, gc, compactor, compaction-coordinator, monitor, and sserver. The result is a denial of service against the distributed data store, disrupting availability for all cluster consumers until an administrator manually restarts the affected components. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Accumulo user account that has been granted cluster access but has NOT been granted the Accumulo SYSTEM-level permission - meaning any standard end-user account qualifies. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is moderate and appropriately categorized as such by the Apache project. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with access to any valid Accumulo user account on a cluster running version 2.1.4 or 2.1.5 connects remotely using standard Accumulo client tooling and issues a graceful shutdown command targeting the manager or tablet servers. No special exploit code is required beyond knowledge of the Accumulo administrative API or shell client. … |
| Remediation | Upgrade to Apache Accumulo 2.1.6, the current Long-Term Maintenance release, which directly addresses this privilege enforcement failure. … Detailed patch versions, workarounds, and compensating controls in full report. |
