Multiple Vulnerabilities on Samsung SRN-1670D

We identified multiple security vulnerabilities that affect Samsung SRN cameras. These issues permit a remote, unauthenticated attackers to gain full control over the device. We thank the CMU CERT for having coordinated the disclosure process.

Backdoor access to Techboard/Syac devices

During a security assessment on one of our customers, we had the opportunity to analyze a device by Techboard/Syac, a manufacturer of digital video recorders (DVR) and network cameras. In particular, our analysis focused on a device of the DigiEye product line. The assessment led to the identification of a "backdoor" service, originally introduced by the device manufacturer for testing and support purposes, that could be abused by remote attackers to execute arbitrary commands on the device, with administrative privileges.

Attack campaign targeting Apache Struts2 vulnerability

At the beginning of March, a security advisory was published about two high-impact issues affecting Apache Struts2, a widely-used framework to create Java web applications. Despite they can be exploited to cause either a DoS (CVE-2014-0050) or to gain remote code execution on the affected server (CVE-2014-0094), these vulnerabilities have not raised much interest until a proof-of-concept exploit was published on a Chinese blog in April, followed by a more detailed write-up describing the technical details of the attack. In addition, on April 24th, researchers from Vulnhunt showed the inefficacy of the countermeasures initially proposed as a workaround to address the bugs. As usually happens in these cases, after the publication of the PoC attackers started to mass-scan the Internet, searching for vulnerable servers. As a consequence, in these days we observed automated attacks trying to exploit CVE-2014-0094. All the attacks we observed so far are originated from a single source IP, namely
