CVE-2022-27509Network attack vector

Unauthenticated redirection to malicious websites

Published Jul 28, 2022 · Updated Sep 16, 2024

Open redirection in Citrix ADC and Citrix Gateway 12.1, 13.0, and 13.1 allows remote attackers to redirect users via crafted URLs. Citrix has not published the affected request handler, parameter, or validation failure that permits an external destination. The appliance must run a VPN Gateway or AAA virtual server, and a victim must follow the attacker-crafted link; the disclosed consequence is redirection to a malicious website.
