What the vulnerability does

Description

Open ISES Tickets before 3.44.2 disables TLS certificate verification in rm/incs/mobile_login.inc.php by setting CURLOPT_SSL_VERIFYPEER to false (and not setting CURLOPT_SSL_VERIFYHOST) when issuing outbound HTTPS requests issued during the mobile (RouteMate) login flow. An attacker positioned on the network path between the server and the remote endpoint can present a forged certificate to intercept, monitor, or modify the request and response, including any API keys or session-bearing data in transit.
