Vulnerability Note VU#913000

Original Release Date: 2016-01-12 | Last Revised: 2016-01-25

Overview

The Samsung SRN-1670D camera contains multiple vulnerabilities.

Description

CWE-264: Permissions, Privileges, and Access Controls - CVE-2015-8279

An undocumented PHP request may be used to read arbitrary files from the system.

CWE-200: Information Exposure - CVE-2015-8280

The interface provides too many details in errors messages, which may allow an attacker to determine user credentials.

CWE-327: Use of a Broken or Risky Cryptographic Algorithm - CVE-2015-8281

The firmware filesystem uses a weak custom encryption scheme based only on simple XOR operations. Vendors should not attempt to implement their own cryptographic methods.

According to the researchers, the Samsung SRN-1670D (Web Viewer Version 1,0,0,193, Date Created 2013.10.26) is affected; other Samsung SRN model cameras may be affected. This device appears to be manufactured by another company named Hanwha.

More information can be found in the researchers' blog.

Impact

An unauthenticated remote attacker may access arbitrary files on the device, and learn user credentials.

Solution

The CERT/CC is currently unaware of a practical solution to this problem.

Hanwha has stated that this model is no longer in production and will not receive any updates.
