CVE-2026-35560: CWE-295: Improper Certificate Validation in Amazon Amazon Athena ODBC driver
Improper certificate validation in the identity provider connection components in Amazon Athena ODBC driver before 2.1.0.0 might allow a man-in-the-middle threat actor to intercept authentication credentials due to insufficient default transport security when connecting to identity providers. This only applies to connections with external identity providers and does not apply to connections with Athena. To remediate this issue, users should upgrade to version 2.1.0.0.
AI Analysis
Technical Summary
The vulnerability CVE-2026-35560 (CWE-295) affects Amazon Athena ODBC driver versions before 2.1.0.0. It is caused by insufficient certificate validation in the identity provider connection components, specifically when connecting to external identity providers. This flaw could enable a man-in-the-middle attacker to intercept authentication credentials due to inadequate transport security. The vulnerability does not impact connections made directly to Athena itself. The vendor advisory from AWS recommends upgrading the ODBC driver to version 2.1.0.0 to address this issue.
Potential Impact
Successful exploitation of this vulnerability could lead to interception of authentication credentials by a man-in-the-middle attacker during connections to external identity providers. This compromises confidentiality and integrity of authentication data but does not affect availability. The CVSS 3.1 base score is 7.4 (high), reflecting network attack vector, high impact on confidentiality and integrity, and requiring no privileges or user interaction.
Mitigation Recommendations
AWS recommends upgrading the Amazon Athena ODBC driver to version 2.1.0.0 to remediate this vulnerability. No other mitigation or temporary fix is indicated. Patch status is confirmed by the vendor advisory. Users should verify they are running version 2.1.0.0 or later to ensure protection against this issue.
