CVE-2017-7852: Dlink dcs-2230l firmware cross-site request forgery vulnerability

Dlink · Dcs 2230l Firmware

D-Link DCS cameras have a weak/insecure CrossDomain.XML file that allows sites hosting malicious Flash objects to access and/or change the device's settings via a CSRF attack. This is because of the 'allow-access-from domain' child element set to *, thus accepting requests from any domain. If a victim logged into the camera's web console visits a malicious site hosting a malicious Flash file from another Browser tab, the malicious Flash file then can send requests to the victim's DCS series Camera without knowing the credentials. An attacker can host a malicious Flash file that can retrieve Live Feeds or information from the victim's DCS series Camera, add new admin users, or make other changes to the device. Known affected devices are DCS-933L with firmware before 1.13.05, DCS-5030L, DCS-5020L, DCS-2530L, DCS-2630L, DCS-930L, DCS-932L, and DCS-932LB1.
