CVE-2021-33330: Exposure of Resource to Wrong Sphere in Liferay Portal

Liferay Portal 7.2.0 through 7.3.2, and Liferay DXP 7.2 before fix pack 9, allows access to Cross-origin resource sharing (CORS) protected resources if the user is only authenticated using the portal session authentication, which allows remote attackers to obtain sensitive information including the targeted user’s email address and current CSRF token.

Root Cause Analysis

The vulnerability stems from improper CORS authentication validation. Key components would be:

The CORS filter handling request authentication checks (CorsFilter#doFilter)
The CSRF token endpoint exposing sensitive data (CSRFTokenServlet#doGet). These functions are identified based on Liferay's security architecture patterns and the vulnerability's description of CORS misconfiguration with session authentication. The confidence is medium due to reliance on architectural inference rather than direct patch analysis.
