Cognos Controller Vulnerability: Unsecured Authorization Tokens and Session Cookies

CVE-2021-20450

What is CVE-2021-20450?

The IBM Cognos Controller is susceptible to a vulnerability which affects the handling of authorization tokens and session cookies by failing to set the secure attribute. This oversight creates an avenue for potential attackers to intercept cookie values. By crafting an HTTP link and enticing users to click it, attackers can capture cookie data as it is transmitted insecurely. Consequently, if users access affected versions of the Cognos Controller, the integrity of their sessions may be compromised, leading to unauthorized access to sensitive information. Secure handling of session tokens is critical to maintaining the confidentiality and security of user sessions.
