Millions of IoT Devices Possibly Affected by ‘Devil’s Ivy’ Flaw

A vulnerability dubbed by researchers “Devil’s Ivy,” which exists in an open source library present in the products of many companies, could affect millions of security cameras and other Internet of Things (IoT) devices.

A vulnerability dubbed by researchers “Devil’s Ivy,” which exists in an open source library present in the products of many companies, could affect millions of security cameras and other Internet of Things (IoT) devices.

The flaw, a stack-based buffer overflow, was discovered by IoT security startup Senrio in a camera from Axis Communications, one of the world’s largest security camera manufacturers.

The weakness, tracked as CVE-2017-9765, can be exploited to cause a denial-of-service (DoS) condition and to execute arbitrary code. Senrio has published a technical advisory and a video showing how an attacker could exploit the flaw to hijack a security camera and gain access to its video feed.

“When exploited, [the vulnerability] allows an attacker to remotely access a video feed or deny the owner access to the feed,” Senrio said in a blog post. “Since these cameras are meant to secure something, like a bank lobby, this could lead to collection of sensitive information or prevent a crime from being observed or recorded.”

Axis has determined that the vulnerability impacts nearly 250 of its camera models and it has started releasing firmware updates that patch the bug. The company has notified its customers and partners of Devil’s Ivy.

An investigation revealed that the security hole was actually in gSOAP, a development toolkit that simplifies the use of XML in server and client web applications. gSOAP is used by most of the top Fortune 500 companies and its developer, Genivia, claims it has been downloaded more than one million times.

The library is also used by some members of the ONVIF Forum, an organization that focuses on standardizing IP connectivity for cameras and other physical security products. ONVIF was established by Axis, Bosch and Sony in 2008 and its current members also include Canon, Cisco, D-Link, Honeywell, Huawei, Netgear, Panasonic, Siemens and Toshiba.

Senrio believes the Devil’s Ivy vulnerability could affect tens of millions of systems to some degree. A Shodan search conducted by the company on July 1 uncovered nearly 15,000 Axis dome cameras accessible from the Internet.

However, Genivia, which provided patches and mitigations, believes the vulnerability is not easy to exploit for arbitrary code execution.

Axis also pointed out in its advisory that exploitation of the flaw for code execution requires a skilled and determined attacker. The hacker needs to have access to the network housing the vulnerable device, but products exposed to the Internet are at much higher risk.

Both Axis and Senrio have advised users to place their cameras and other IoT devices behind a firewall to reduce the risk of exploitation.
