Directory traversal vulnerability in FlexWATCH Network Camera 3.0 and earlier allows remote attackers to bypass access restrictions for (1) admin/aindex.asp or (2) admin/aindex.html via a .. (dot dot) and encoded / (%2f) sequence in the URL. FlexWatch is prone to an authorization-bypass vulnerability. This issue is due to a failure in the application to properly verify user-supplied input. An attacker can exploit this issue to bypass the authorization mechanism. This allows the attacker to gain unauthorized access to the surveillance system. Versions 3.0 and prior are affected.

Hardcore Disassembler / Reverse Engineer

Reversing must be a passion as your skills will be challenged on a daily basis and you will be working several hours everyday in IDA, Ollydbg, and with BinDiff. Often, it is also required that you write a PoC or even a working exploit to prove that an issue is exploitable.

1) Input passed via the URL isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

SOLUTION: Filter malicious characters and character sequences in a proxy server or firewall with URL filtering capabilities.
