Description Preview
IBM QRadar User Behavior Analytics versions 1.0.0 through 4.1.0 contains a vulnerability where web pages can be stored locally on the system. This creates an information disclosure risk as these locally stored pages can be accessed and read by other users on the same system. This vulnerability is classified as CWE-922 (Insecure Storage of Sensitive Information).
Overview
This vulnerability (CVE-2021-20391) affects IBM QRadar User Behavior Analytics versions 1.0.0 through 4.1.0. The issue stems from improper storage of web pages locally on the system, which violates proper data isolation principles. When web pages are stored locally without proper access controls, any user with access to the system could potentially view sensitive information contained in these pages. This could lead to unauthorized information disclosure, potentially exposing sensitive data or configuration details that should remain private to specific authorized users.
Remediation
Organizations using affected versions of IBM QRadar User Behavior Analytics should:
- Update to the latest version as recommended by IBM in their security bulletin
- Review system access controls to limit which users can access the system
- Implement the specific fixes outlined in IBM's security advisory at https://www.ibm.com/support/pages/node/6453103
- Conduct a security review to ensure no sensitive information has been compromised
- Consider implementing additional access controls or file system restrictions to prevent similar issues
