CVE-2026-24014 in IoTDB
Summary
by MITRE • 07/06/2026
Apache IoTDB DataNode’s internal RPC interface for creating Trigger instances uses the uploaded Trigger JAR name to build a file path without sufficient validation. If the internal DataNode RPC port is exposed to an untrusted network, an attacker may use path traversal sequences in the JAR name to write files outside the intended Trigger installation directory. This could allow arbitrary file write with the permissions of the IoTDB process.
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.
Once again VulDB remains the best source for vulnerability data.

The vulnerability in Apache IoTDB DataNode represents a critical path traversal flaw that exploits insufficient input validation within the trigger installation mechanism. This weakness exists in the internal Remote Procedure Call interface responsible for creating trigger instances, where the system directly incorporates user-supplied JAR file names into file paths without proper sanitization or validation. The flaw manifests when the DataNode RPC port is accessible from untrusted networks, creating an attack surface where malicious actors can manipulate the JAR name parameter to include directory traversal sequences such as "../" that allow them to write files outside of the designated trigger installation directory.
The technical implementation of this vulnerability stems from inadequate input validation practices within the file path construction logic. When IoTDB processes a trigger creation request, it accepts the JAR file name directly from the RPC payload and uses it to construct filesystem paths without proper sanitization. This design flaw aligns with CWE-23 Path Traversal vulnerabilities, specifically categorized under path traversal in file operations where insufficient validation allows attackers to manipulate file system access patterns. The vulnerability operates at the intersection of insecure direct object references and improper input validation, creating a scenario where arbitrary file write capabilities can be achieved through controlled manipulation of the JAR name parameter.
The operational impact of this vulnerability extends beyond simple unauthorized file writes, as it provides attackers with the ability to execute arbitrary code with the privileges of the IoTDB process. This privilege escalation potential creates significant security implications for IoTDB deployments, particularly in environments where the DataNode RPC interface is exposed to external networks or untrusted parties. Attackers could potentially overwrite critical system files, inject malicious code into the trigger execution environment, or establish persistence mechanisms within the IoTDB service. The vulnerability affects all versions from 1.3.3 through 2.0.7, representing a substantial attack surface for organizations running these older versions.
The remediation strategy focuses on upgrading to Apache IoTDB version 2.0.8 or later, which implements proper input validation and sanitization of JAR file names during trigger installation processes. This fix addresses the root cause by ensuring that all user-supplied file path components are properly validated before being used in filesystem operations. Organizations should also implement network segmentation to restrict access to internal RPC interfaces, employ principle of least privilege configurations for IoTDB processes, and conduct regular security assessments of their IoTDB deployments. Additional mitigations include monitoring for suspicious file creation patterns and implementing network-level controls that prevent unauthorized access to the DataNode RPC ports, aligning with ATT&CK technique T1059 Command and Scripting Interpreter and T1210 Exploitation of Remote Services. The vulnerability highlights the importance of input validation in security-critical components and demonstrates how seemingly minor implementation flaws can lead to significant privilege escalation capabilities in distributed systems.
