Description

Authentication Bypass by Spoofing vulnerability in Apache IoTDB. Certain Thrift RPC query handlers lack strict validation of the sessionId parameter. An attacker can construct requests with a forged sessionId and, without performing openSession authentication, receive valid query results. This allows authentication bypass and unauthorized reading of time-series data. 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.

Affected products

• Apache Software Foundation Apache IoTDB: from 1.3.3 before 2.0.8 — fixed in 2.0.8

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache IoTDB 2.0.8. Check the vendor advisory for mitigations.
