Executive brief
DataEase is an open-source data visualization and analysis platform. A security vulnerability in how it handles Amazon Redshift data source connections allows an attacker to execute arbitrary commands on the server. This could lead to a complete system takeover, unauthorized access to sensitive business data, and disruption of operations. Organizations using DataEase should upgrade to version 2.10.23 or later to mitigate this risk.
Technical details
DataEase is vulnerable to a reflection-based Remote Code Execution (RCE) chain within its Redshift data source connector. The vulnerability stems from the Amazon Redshift JDBC driver's behavior of automatically searching for and loading a configuration file named 'rsjdbc.ini' from several locations, including the system's temporary directory. An attacker who can place a malicious configuration file in this directory can specify a 'socketFactory' (such as Spring's FileSystemXmlApplicationContext) and a 'socketFactoryArg' pointing to a malicious XML payload. When a JDBC connection is subsequently initiated through 'io.dataease.datasource.type.Redshift', the driver instantiates the attacker-controlled class, leading to code execution. This effectively bypasses existing Redshift driver security mechanisms. The issue is resolved in version 2.10.23 by explicitly nullifying the relevant system properties.
