Technical details

A command injection vulnerability (CWE-77) exists in the authentication components of the Amazon Athena ODBC driver, specifically affecting the BrowserSSOOIDC, BrowserAzureAD, and BrowserSAML plugins. The flaw stems from improper neutralization of special elements within connection parameters processed during user-initiated authentication. An attacker can exploit this by providing specially crafted connection strings that, when processed by the driver, lead to arbitrary code execution or the redirection of authentication flows. The vulnerability is addressed in version 2.1.0.0, which implements improved input validation and security controls such as PKCE for OAuth flows.
