CVE-2026-9437 Details
Description
A vulnerability has been found in DTStack Taier 1.4.0. This affects the function Runtime.exec of the component REST API. The manipulation of the argument sqlText leads to os command injection. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A critical stored injection vulnerability allowing remote code execution has been identified in DTStack Taier version 1.4.0. This issue arises in the REST API component, where user-supplied SQL text is improperly sanitized before being executed as operating system commands. The vulnerability exploitation involves injecting malicious commands through the 'sqlText' parameter, which is then executed via 'Runtime.exec()' with a 'sh -c' prefix.
To address this vulnerability, implement input validation to reject shell metacharacters in the 'sqlText' parameter. Switch from 'Runtime.exec()' to 'ProcessBuilder' with explicit argument lists for command execution. Consider allowing only a predefined list of commands to be executed and ensure that processes are run with minimal operating system privileges.
