Subject:  Trend micro - IWSVA/IWSS - Authorization module password leak

There is possbile get username and password from "Proxy-Authorization" header, which is not correctly removed when authorization header
 sends WMP.

Requirements:

- IWSVA/IWSS basic authorization on
- Client is using WMP (8-11) as video player
- Standalone proxy (if upstream proxy is used, "Proxy-Authorization" header is removed by this upstream proxy)

Bug:

WMP sends authorization header in this format:

Proxy-Authorization: basic =xxxxxxxxxx

In that case IWSVA/IWSS extract correct authorization information, but it does not remove this Proxy-Authorization header. (it seems
 because of lovercase "b" in basic, even if IWSVA/IWSS knows, that this is authorization header and can extract correct username/password).


Scenario:

Some "bad" guy knows, that company XY use IWSVA/IWSS and basic authorization, so he sends them url with prepared video stream (whatever
 format for WMP) and waits for users access. When user access this url, "bad" guy gets whole "Proxy-Authorization" header which contains
 also base64 hash with username/password.


Happy pentesting..
