[Vulnerability Type]
Server Side Request Forgery


[Affected Component]
MailConnect


[CVE Reference]
CVE-2018-15517


[Security Issue]
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.
