CVE-2021-27701

Vulnerability

Description

The Socifi Guest wifi SaaS application is affected by a Cross-Site Request Forgery (CSRF) vulnerability. The application does not implement CSRF tokens or perform request validation, leaving it open to forged requests [1].

Attack

Vector

An attacker can craft a malicious CSRF request that, when executed by an authenticated administrator or user, will add or modify any random user data on the Socifi wifi portal. No additional authentication or session management bypass is required beyond tricking a legitimate user into submitting the forged request [1].

Impact

Successful exploitation allows an attacker to modify user data without authorization. This could lead to unauthorized changes in user profiles, settings, or potentially privilege escalation depending on the application logic [1].

Mitigation

As of the publication date (2024-11-12), the vendor has not released a patch or provided a workaround. The application does not implement standard CSRF protections such as anti-CSRF tokens or same-origin policy enforcement. Users are advised to apply generic CSRF mitigation techniques, such as implementing a CSRF token in all state-changing requests [1].
