Description
Casdoor is a UI-first Identity and Access Management (IAM) / Single-Sign-On (SSO) platform. In Casdoor 1.577.0 and earlier, a logic vulnerability exists in the beego filter CorsFilter that allows any website to make cross domain requests to Casdoor as the logged in user. Due to the a logic error in checking only for a prefix when authenticating the Origin header, any domain can create a valid subdomain with a valid subdomain prefix (Ex: localhost.example.com), allowing the website to make requests to Casdoor as the current signed-in user.

Weakness
CWE-942: Permissive Cross-domain Security Policy with Untrusted Domains
The product uses a web-client protection mechanism such as a Content Security Policy (CSP) or cross-domain policy file, but the policy includes untrusted domains with which the web client is allowed to communicate.
How to prevent it
- Architecture and Design, Operation: Define a restrictive Content Security Policy [REF-1486] or cross-domain policy file.
- Architecture and Design, Operation: Avoid using wildcards in the CSP / cross-domain policy file. Any domain matching the wildcard expression will be implicitly trusted, and can perform two-way interaction with the target server.
- Architecture and Design, Operation: For Flash, modify crossdomain.xml to use meta-policy options such as 'master-only' or 'none' to reduce the possibility of an attacker planting extraneous cross-domain policy files on a server.
