Product: Samsung DVR Impact: High Intro ~~~~~~~~~~~~~~~ Samsung DVR Web Viewer is by default using HTTP (port 80) and transmits the credentials encoded in the Cookie header using very bad security practice, just encoding the login and password in BASE64 codification. It is trivial to decode those values and gain access to Samsung DVR web interface to monitor and control IP cameras, if the default credentials have been changed. Vulnerable code ~~~~~~~~~~~~~~~ http://192.168.1.23/cgi-bin/webviewer_login_page?lang=en (line 48) document.cookie='ID='+encode64(document.login_page.id.value) + '&PWD='+encode64(document.login_page.pwd.value) + '&SessionID='+Math.random(); Mitigation ~~~~~~~~~~~~~~~ Do not transmit sensitive data encoded in BASE64 and use TLSv1.2 by default.
