AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a cross-tenant authentication issue in multiple WSO2 products caused by improper cryptographic design in Adaptive Authentication. Specifically, a single cryptographic key is used across all tenants to sign authentication cookies. This allows a privileged user in one tenant to forge authentication cookies for users in other tenants, potentially gaining unauthorized access.
How can this vulnerability impact me? :
If exploited, this vulnerability can allow an attacker with high privileges in one tenant to gain unauthorized access to accounts in other tenants, potentially taking over those accounts. The impact is significant because it affects confidentiality, integrity, and availability of user accounts across tenants. However, exploitation requires access to Adaptive Authentication functionality and the Auto-Login feature must be enabled.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, you should disable the Auto-Login feature in your WSO2 products, as the vulnerability is only exploitable when Auto-Login is enabled. Additionally, restrict access to the Adaptive Authentication functionality to only the highest privileged users to reduce risk.
