This flaw resides in the browser-based authentication components, where insufficient security controls could enable attackers to intercept or hijack legitimate authentication sessions. The vulnerability stems from inadequate protection mechanisms within the authentication flows, leaving users susceptible to unauthorized access. To mitigate this risk, Amazon recommends that users immediately upgrade to version 2.1.0.0 of the Athena ODBC driver. The affected driver is used on Windows, Linux, and macOS operating systems to connect to the Amazon Athena service. Successful exploitation could lead to unauthorized data access and manipulation within the victim\u0026rsquo;s Athena environment.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies a target using a vulnerable version of the Amazon Athena ODBC driver (prior to 2.1.0.0).\u003c/li\u003e\n\u003cli\u003eThe attacker intercepts the browser-based authentication flow initiated by the ODBC driver.
