Detailsinfo

A vulnerability was found in D-Link DNS-343 ShareCenter up to 1.05. It has been rated as critical. Affected by this issue is an unknown function of the file /goform/Mail_Test of the component Endpoint. The manipulation with an unknown input leads to a os command injection vulnerability.

Impacted is confidentiality, integrity, and availability. CVE summarizes:

D-Link DNS-343 ShareCenter devices running firmware versions up to and including 1.05 contain a command injection vulnerability in the Mail Test functionality. The web maintenance script posts to the internal goForm endpoint '/goform/Mail_Test' and uses several form parameters directly in a call to a system email utility without proper input validation. An unauthenticated remote attacker can supply crafted form data that injects shell commands, resulting in execution as root on the device. NOTE: The DNS-343 product line has been declared end-of-life.
