Summary

Oqtane Framework before 10.3.0 contains a broken access control flaw in SettingController that lets an authenticated site administrator read and modify settings belonging to other sites in the same tenant database. The flaw, tracked as CWE-639, arises because the requested entityId for Site or Role settings is not checked against the current site. An attacker with site administrator access can use the /api/setting endpoints to read private values such as SMTP passwords and client secrets and to change another site's OIDC or OAuth2 authentication configuration, without host privileges.

Description from the CNA

Oqtane Framework before 10.3.0 contains a broken access control vulnerability in SettingController.cs that allows an authenticated site administrator to read and modify settings belonging to other sites within the same tenant database by supplying an arbitrary entityId for Site or Role type settings, since IsAuthorized and FilterPrivate fail to verify the requested site matches the current alias SiteId. Attackers can exploit the /api/setting endpoints to disclose private values such as SMTPPassword, SMTPClientSecret, and ExternalLogin ClientSecret, and to alter another site's OIDC/OAuth2 authentication configuration without requiring host privileges.
