Technical details

An OS command injection vulnerability exists in the browser-based authentication component of the Amazon Athena ODBC driver for Linux. The flaw is rooted in the improper neutralization of special elements within connection parameters that are processed when the driver launches a browser for authentication. A local attacker can exploit this by providing specially crafted connection strings; when a user initiates a connection using these parameters, the driver executes arbitrary shell commands with the privileges of the local user. This issue was specifically addressed by improving the browser launch mechanism to use safer system APIs. Users should upgrade to version 2.0.5.1 or later to remediate this vulnerability.
