DESCRIPTION:
Luigi Auriemma has discovered two vulnerabilities in Siemens SIMATIC
WinCC Flexible, which can be exploited by malicious people to
disclose potentially sensitive information and cause a DoS (Denial of
Service).

1) An input sanitisation error in Miniweb.exe when handling HTTP GET
requests can be exploited to download arbitrary files via directory
traversal attacks sent in a web request.

2) An input validation error in Miniweb.exe when handling HTTP POST
requests can be exploited to crash the process via specially crafted
content sent in a web request.

The vulnerabilities are confirmed in version 2008 SP2 Upd13
(K01.03.02.13_01.02.00.01). Other versions may also be affected.

SOLUTION:
Restrict access to trusted hosts only.
