D-LINK Central WifiManager (CWM 100) 1.03 r0098 Server-Side Request Forgery

Using a web browser or script server-side request forgery (SSRF) can be initiated against internal/external systems to conduct port scans by leveraging D-LINK’s MailConnect component. The MailConnect feature on D-Link Central WiFiManager CWM-100 version 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/ 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.
