CVE-2026-24013 in IoTDB
Summary
by MITRE • 07/06/2026
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.

The vulnerability described represents a critical authentication bypass flaw in Apache IoTDB that stems from insufficient validation of session identifiers within the Thrift RPC query handlers. This weakness allows malicious actors to circumvent the normal authentication process by crafting specially constructed requests containing forged session IDs, thereby gaining unauthorized access to time-series data without proper authentication. The vulnerability affects versions from 1.3.3 through 2.0.7, creating a significant security gap that could compromise the integrity and confidentiality of time-series databases deployed in industrial IoT environments.
The technical root cause of this issue lies in the improper validation of the sessionId parameter within the RPC query handlers, which violates fundamental security principles of authentication mechanisms. According to CWE-287, this vulnerability manifests as an improper authentication flaw where the system fails to adequately verify session identifiers before granting access to protected resources. The implementation allows for session spoofing attacks where an attacker can construct malicious requests with fabricated session IDs that appear valid to the system, bypassing the openSession authentication procedure entirely.
Operationally, this vulnerability creates severe consequences for organizations using Apache IoTDB in industrial settings where time-series data often contains sensitive operational information. The impact extends beyond simple unauthorized access to include potential data exfiltration, system compromise, and disruption of critical operations. Attackers can exploit this weakness to read confidential time-series data without detection, potentially accessing proprietary operational metrics, sensor readings, or other sensitive information that could be valuable for competitive advantage or malicious activities.
The threat landscape surrounding this vulnerability aligns with ATT&CK technique T1078.004 which covers valid accounts used for lateral movement and privilege escalation. This authentication bypass allows attackers to operate under seemingly legitimate session contexts, making detection more challenging while enabling persistent access to database resources. Organizations deploying IoTDB systems face particular risk as these environments often contain critical infrastructure data where unauthorized access could result in operational disruption or security breaches.
Mitigation efforts should prioritize immediate upgrade to Apache IoTDB version 2.0.8, which addresses the session validation weakness through enhanced authentication mechanisms. Organizations should also implement additional defensive measures including network segmentation, monitoring for unusual authentication patterns, and regular security assessments of their IoT infrastructure. The fix implemented in version 2.0.8 likely includes strengthened validation of session identifiers within RPC handlers, ensuring that only properly authenticated sessions can access database resources and preventing the spoofing attacks that previously enabled unauthorized data access.
