Remotely Open User Registration Scanner

The Remotely scanner is utilized to check for vulnerabilities in the Remotely self-hosted remote desktop and collaboration web application. This software is generally used by organizations and individuals for remote access and collaboration purposes. It is popular among IT departments and support teams that need to manage and troubleshoot systems remotely. By ensuring secure configurations, this scanner helps protect sensitive data handled during remote sessions. It assists administrators in identifying potential security lapses in user registration setups. Its primary purpose is to ensure unauthorized users cannot gain access through improperly configured user registration portals.

This scanner targets the Open User Registration vulnerability that exists when user registration on the Remotely application is not appropriately secured with an invitation requirement. The vulnerability could permit unauthorized users to register and access the application. It checks if the registration endpoint is available without an invitation code, which can lead to potential security breaches. Other misconfigurations in the registration process might similarly allow unauthorized access. It helps detect improper security settings that could be exploited.

When enabled, the registration endpoint of Remotely applications could be compromised, exposing sensitive operations to unauthorized users. The scanner checks specific endpoints within the application for sign-up options that do not require an invitation. Technical checks involve verifying HTTP response codes and page content indicating registration availability. It looks for inconsistencies in the expected security configurations, ensuring to flag any open registrations detected. Additionally, it tests for the non-existence of necessary security phrases that should protect against free registration.

If exploited, the Open User Registration vulnerability could lead to unauthorized access, compromising application integrity and sensitive client data. This creates potential routes for malicious users to conduct further attacks. Victims might encounter data exfiltration and infrastructure misuse. Additionally, the system could be used as a leverage point for lateral movement to other network segments. Ensuring control and configuration integrity could prevent the exploitation of such vulnerabilities. Without mitigation, organizations risk exposure to significant operational, financial, and reputational damage.
