Summary
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.
