Description:
Martin O'Neal of Corsaire has discovered a security issue in ServerMask, allowing malicious people to determine if a system is running Microsoft Internet Information Server (IIS) even though the product's functionality should prevent this.
The problem is that ServerMask does not correctly filter out all headers containing information, which may be used to determine the identity of a web server. The following headers can reportedly be used to establish the identity of Microsoft IIS:
- ETag.
- HTTP Status Message.
- Allow: header in response to OPTIONS request.
ServerMask 2.2 and prior are reportedly affected.
Solution:
Reportedly fixed in version 3.0.
Provided and/or discovered by:
Martin O'Neal, Corsaire.
