Improper validation of length fields in the Apache IoTDB RPC service may allow a remote unauthenticated attacker to cause a denial of service. (CVE-2026-44630)
Apache IoTDB versions before 1.3.8 and from 2.0.0 up to but not including 2.0.9 contain a vulnerability in the RPC service where improper validation of length fields can lead to a denial of service. An unauthenticated remote attacker can send a crafted malformed Thrift frame causing the server to allocate excessive memory and crash with an OutOfMemoryError. The issue is fixed in version 2.0.10.
AI Analysis
Technical Summary
The Apache IoTDB RPC service improperly validates length fields in incoming Thrift frames. This flaw allows a remote unauthenticated attacker to send a malformed frame that triggers excessive memory allocation, resulting in an OutOfMemoryError and a denial of service condition. The vulnerability affects versions before 1.3.8 and from 2.0.0 up to 2.0.9. The vendor has addressed this issue in version 2.0.10.
Potential Impact
A remote unauthenticated attacker can cause the Apache IoTDB server to crash by exhausting memory resources, resulting in denial of service. There is no indication of code execution or data compromise from the provided information.
Mitigation Recommendations
Users should upgrade Apache IoTDB to version 2.0.10 or later, where this vulnerability is fixed. No other mitigations or workarounds are indicated in the provided data.
