Overview
The vulnerability described herein, CVE-2025-26795, pertains to the Apache IoTDB JDBC driver. It has the potential to expose sensitive data to unauthorized actors and allows for the insertion of sensitive data into the log file. This vulnerability has a notable impact on users of iotdb-jdbc from versions 0.10.0 to 1.3.3, as well as 2.0.1-beta prior to 2.0.2. Given its severity and potential for system compromise or data leakage, it is a vulnerability that requires immediate attention.

How the Exploit Works
This vulnerability allows an attacker to exploit the Apache IoTDB JDBC driver to expose sensitive information to unauthorized actors. This is possible due to a flaw in the driver’s handling of data, which inadvertently logs sensitive data, thereby making it accessible to unauthorized persons. Additionally, the flaw allows for the insertion of potentially malicious data into the log file, further exacerbating the risk.
Conceptual Example Code
While the exact implementation of the exploit may vary, a conceptual example may resemble the following:
// Instantiate a vulnerable JDBC driver
Driver driver = new IoTDBJDBC();
// Insert sensitive data into log
driver.log(Level.INFO, "Sensitive Information: {0}", new Object[] {sensitiveInfo});
// Expose sensitive data
String exposedData = driver.getLogfile();
This conceptual example demonstrates how an attacker might manipulate the logging functionality of the vulnerable driver to insert sensitive data. This subsequently exposes this data in the log file, accessible to unauthorized actors.
