CVE-2024-36419Network attack vector

Authenticated open redirect via trusted Host header

Published Jun 10, 2024 · Updated Aug 2, 2024

Host header injection in SuiteCRM before 8.6.1 allows remote authenticated users to redirect legacy-route requests to an attacker-chosen host. The /legacy route trusts the request Host header when constructing a redirect destination instead of constraining it to the configured application host. A low-privileged account can influence the resulting redirect and expose request data to an external destination without altering service availability.
