A vulnerability was found in Samsung DVR Web Viewer (version now known) and classified as critical. Affected by this issue is some unknown processing of the component Cookie Handler. The manipulation with an unknown input leads to a missing encryption vulnerability. Using CWE to declare the problem leads to CWE-311. The product does not encrypt sensitive or critical information before storage or transmission. Impacted is confidentiality, integrity, and availability.
The weakness was shared 12/17/2016 as Samsung DVR credentials encoded in base64 in cookie header as not defined mailinglist post (Bugtraq). The advisory is shared for download at seclists.org. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600. The advisory points out:
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.
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
