TITLE:
Microsoft Internet Information Services WebDAV Request Directory
Security Bypass

SECUNIA ADVISORY ID:
SA35109

VERIFY ADVISORY:
http://secunia.com/advisories/35109/

DESCRIPTION:
Nikolaos Rangos has discovered a vulnerability in Microsoft Internet
Information Services (IIS), which can be exploited by malicious
people to bypass certain security restrictions.

The vulnerability is caused due to an error when handling WebDAV
requests for directories requiring authentication. This can be
exploited to bypass access restrictions and e.g. download files from
protected folders by issuing an HTTP GET request containing Unicode
characters and a "Translate: f" HTTP header.

Successful exploitation may allow uploading arbitrary files to
protected WebDAV folders.

The vulnerability is confirmed in Microsoft IIS 5.1 on a fully
patched Windows XP SP3 and reported in version 6.0. Other versions
may also be affected.

SOLUTION:
Do not store sensitive files inside the webroot. Disable WebDAV
support.

PROVIDED AND/OR DISCOVERED BY:
Nikolaos Rangos (Kingcope)
