Executive Summary

IBM Db2 Genius Hub versions 1.1.2 to 1.1.5 have a vulnerability where a missing X-Content-Type-Options header allows MIME type sniffing. This could let a remote authenticated attacker bypass security restrictions.

Detection Guidance

This vulnerability involves missing X-Content-Type-Options header allowing MIME type sniffing. To detect it, check HTTP responses from IBM Db2 Genius Hub for the presence of the X-Content-Type-Options header using tools like curl or browser developer tools. If the header is absent, the system is vulnerable.

Impact Analysis

An attacker could exploit this to bypass security restrictions, potentially accessing unauthorized data or performing actions they shouldn't be able to. This could lead to data leaks or unauthorized system changes.

Compliance Impact

This vulnerability allows remote authenticated attackers to bypass security restrictions due to a missing X-Content-Type-Options header, enabling MIME type sniffing. This could potentially lead to unauthorized access or data exposure, which may impact compliance with standards like GDPR (data protection) or HIPAA (healthcare data privacy) by increasing risks of data breaches or unauthorized information disclosure.

Mitigation Strategies

Configure the web server or application to include the X-Content-Type-Options header set to 'nosniff' to prevent MIME type sniffing. Ensure this header is enforced for all responses from IBM Db2 Genius Hub.
