An issue was discovered in NVR WebViewer on Hanwah Techwin SRN-472s 1.07_190502 devices, and other SRN-x devices before 2019-05-03. A system crash and reboot can be achieved by submitting a long username in excess of 117 characters. The username triggers a buffer overflow in the main process controlling operation of the DVR system, rendering services unavailable during the reboot operation. A repeated attack affects availability as long as the attacker has network access to the device.

Web Viewer for Hanwha DVR 2.17 and Smart Viewer in Samsung Web Viewer for Samsung DVR are vulnerable to XSS via the /cgi-bin/webviewer_login_page data3 parameter. (The same Web Viewer codebase was transitioned from Samsung to Hanwha.)
