AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Network-reachable, low-complexity crafted query with availability-only impact; PR:L because submitting a query normally requires an authenticated IoTDB session despite the vendor's PR:N rating.
Primary rating from Vendor (apache).

Lifecycle Timeline
6DescriptionCVE.org
Uncontrolled Resource Consumption vulnerability in Apache IoTDB.
Some interface fails to impose reasonable limits on the time span and aggregation interval of the query. An attacker can construct a request with extreme parameters (e.g., a very large time range combined with a minimal interval). This forces the DataNode to build an enormous result set in memory, which exhausts the Java heap and causes the DataNode process to crash.
This issue affects Apache IoTDB: from 1.3.3 before 2.0.8.
Users are recommended to upgrade to version 2.0.8, which fixes the issue.

AnalysisAI
Denial of service in Apache IoTDB versions 1.3.3 through 2.0.7 lets remote attackers crash the DataNode process by submitting a single query whose time span and aggregation interval are unbounded. Because the affected query interface enforces no reasonable limit on these parameters, a request combining a very large time range with a minimal interval forces the DataNode to materialize an enormous result set in memory, exhausting the Java heap. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be able to submit an aggregation/range query to an IoTDB DataNode and control the query's time-span bounds and aggregation interval - the concrete trigger is a query combining an extremely large time range with a minimal aggregation interval, which the affected interface fails to cap. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are internally consistent and point to a genuine but bounded availability risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can reach an IoTDB DataNode query endpoint submits a single aggregation query spanning, for example, decades of timestamps with a one-millisecond interval, forcing the server to allocate result buckets far exceeding available heap. The DataNode throws OutOfMemoryError and crashes, disrupting ingestion and queries for the served region until it restarts. … |
| Remediation | Vendor-released patch: Apache IoTDB 2.0.8 - upgrade all DataNode instances to 2.0.8 or later, which imposes limits on query time span and aggregation interval; see the Apache advisory at https://lists.apache.org/thread/0g5th1t2vj6j8hm5t9w3xh9n6f6ht9z8. … Detailed patch versions, workarounds, and compensating controls in full report. |
