Using a web browser or script SSRF can be initiated against internal/external systems to conduct port scans by leveraging D LINKs MailConnect component. The MailConnect feature on D-Link Central WiFiManager CWM-100 1.03 r0098 devices is intended to check a connection to an SMTP server but actually allows outbound TCP to any port on any IP address, leading to SSRF, as demonstrated by an index.php/System/MailConnect/host/127.0.0.1/port/22/secure/ URI. This can undermine accountability of where scan or connections actually came from and or bypass the FW etc. This can be automated via script or using Web Browser.
