Details
Note: The exploit requires credentials to be successful.
There exists an authenticated buffer overflow vulnerability in the accused cameras that can be exploited by malicious users. It occurs when a large string is passed in the WEPEncryption parameter provided to wireless.htm. The variable is expected to be a single character of some value between 0 and 4 based on radio buttons selected by the user. Because of this assumption the length of the string is never verified and passed directly to strcpy() which copies directly to a stack variable. This overwrite can be used to gain control of the return address and possible to execute arbitrary code.
New Features:None
