SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to versions 7.15.1 and 8.9.3, SuiteCRM contains an unauthenticated open redirect vulnerability in the WebToLead capture functionality.

Versions 7.15.1 and 8.9.3 patch the issue.

Attack-Flow Graph

Executive Summary

This vulnerability exists in SuiteCRM, an open-source Customer Relationship Management software. Before versions 7.15.1 and 8.9.3, the WebToLead capture functionality contains an unauthenticated open redirect flaw. Specifically, a user-supplied POST parameter is used as a redirect destination without proper validation.

This means attackers can craft requests that cause SuiteCRM to redirect users to arbitrary external websites, potentially malicious ones.

Impact Analysis

The vulnerability allows attackers to abuse the trusted SuiteCRM domain to redirect users to malicious external websites. This can be used for phishing and social engineering attacks, tricking users into revealing sensitive information or downloading malware.

Because the redirect is unauthenticated and uses user-supplied input without validation, it can be exploited by anyone to target SuiteCRM users or visitors.
