TITLE:
Internet Explorer HTTP Request Smuggling/Splitting Vulnerabilities

SECUNIA ADVISORY ID:
SA29453

VERIFY ADVISORY:
http://secunia.com/advisories/29453/

CRITICAL:
Less critical

IMPACT:
Security Bypass, Cross Site Scripting

WHERE:
From remote

SOFTWARE:
Microsoft Internet Explorer 7.x
http://secunia.com/product/12366/

DESCRIPTION:
Stefano Di Paola has reported some vulnerabilities in Internet
Explorer, which can be exploited by malicious people to conduct HTTP
request smuggling/splitting attacks.

The problem is that it is possible to modify certain headers via
"setRequestHeader()", which can be exploited to e.g. inject arbitrary
HTTP requests by setting the "Transfer-Encoding" header to "chunked"
or to overwrite certain headers (e.g. "Content-Length", "Host", and
"Referer").

The vulnerabilities are reported in version 7.0.5730.11. Other
versions may also be affected.

SOLUTION:
Do not browse untrusted websites.

PROVIDED AND/OR DISCOVERED BY:
Stefano Di Paola
