Summary

Improper validation of length fields in the Apache IoTDB RPC service may allow a remote unauthenticated attacker to cause a denial of service. By sending a crafted malformed Thrift frame, an attacker can cause IoTDB to allocate an excessive amount of memory and crash with an OutOfMemoryError. Affects versions before 1.3.8 and from 2.0.0 before 2.0.9. Users are recommended to upgrade to version 2.0.10.

Risk Assessment

An attacker can remotely cause the IoTDB service to crash, leading to system unavailability and potential operational disruptions.

Recommendation

Upgrade Apache IoTDB to version 2.0.10 or later immediately.
