A report has been made by a company called Senrio that millions of IoT devices are vulnerable to Cybersecurity attacks due to a vulnerability initially discovered in remote security cameras. The firm found a weakness in a security camera developed by Axis Communications, one of the world's biggest manufacturers of the devices.

The Model 3004 security camera is used for security at the Los Angeles International Airport and other places.  The problem turned out to be a stack buffer overflow vulnerability, which the firm dubbed "Devil's Ivy."

Axis notified the security firm that 249 different models of the camera were affected by the vulnerability. It found only three models that were unaffected.

The problem lies deep in the communication layer of gSOAP, an open source third-party toolkit that uses various device makers for IoT technology, according to Senrio.

gSOAP manager Genivia reported that the toolkit has been downloaded over 1 million times, according to Senrio. Most of the downloads likely involved developers. Major companies including IBM, Microsoft, Adobe and Xerox are customers of the firm.

Genivia issued a new patch for gSOAP within 24 hours of being alerted to the vulnerability, and said it notified customers of the problem. The obscure problem was caused by an intended integer underflow, followed by a second unintended integer underflow that triggered the bug, Van Engelen told LinuxInsider.

"The trigger happens when at least 2 GB of XML data is uploaded to a Web server," van Engelen explained. "This bug was not discovered by proprietary static analysis tools or by our source code users who looked at the source code since 2002.

Certain ONVIF devices act as Web servers, making them vulnerable when configured to accept more than 2 GB of XML data, he noted.
