Description
A vulnerability was identified in 6amTech 6valley 16.0. Impacted is the function existingAccountCheck of the file /api/v1/auth/existing-account-check of the component Social Login Flow. Such manipulation of the argument user_response leads to authorization bypass. The attack may be launched remotely. The exploit is publicly available and might be used.
An authorization bypass vulnerability has been identified in 6amTech 6valley version 16.0, specifically within the social login flow. The issue arises in the 'existingAccountCheck' function of the 'SocialAuthController', located at '/api/v1/auth/existing-account-check'. This vulnerability allows for unauthenticated account takeover by manipulating the 'user_response' argument. The endpoint trusts client-supplied data without proper validation, enabling attackers to gain access to victims' accounts by simply providing their email addresses. The vulnerability can be exploited remotely, and public exploit details are available.
To address this vulnerability, implement server-side validation of social provider tokens before granting access tokens. Alternatively, require an additional verification step to confirm identity before issuing tokens. It is also recommended to eliminate the user enumeration feature in the response for unknown emails.
