Vulnerability Description

TrendNet ProView Wireless camera TV-IP512WN (version v1.0R) is vulnerable to buffer overflow in handling RTSP packet in firmware version 1.0.4 which may result in remote code execution or denial of service. The issue is in the binary rtspd which resides in /sbin folder which is responsible for serving rtsp connection received by the device. The problem arises in parsing “Authorization: Basic” RTSP header which could be arbitrarily long, the value of this header is copied onto stack memory without any bounds check which could lead to a buffer overflow. What makes this vulnerability more severe is that the user need not be authenticated to trigger the overflow.
