TITLE:
Apache "Expect" Header Cross-Site Scripting Vulnerability

SECUNIA ADVISORY ID:
SA21172

VERIFY ADVISORY:
http://secunia.com/advisories/21172/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Apache 1.3.x
http://secunia.com/product/72/
Apache 2.0.x
http://secunia.com/product/73/
Apache 2.2.x
http://secunia.com/product/9633/

DESCRIPTION:
Thiago Zaninotti has discovered a vulnerability in Apache HTTP
Server, which can be exploited by malicious people to conduct
cross-site scripting attacks.

Input passed to the "Expect:" header is not properly sanitised before
being returned to users. This can be exploited to execute arbitrary
HTML and script code in a user's browser session in context of a
vulnerable site.

The vulnerability affects versions prior to 1.3.35, 2.0.58, and
2.2.2.

Secunia has constructed a test, which is available at:
http://secunia.com/expect_header_cross-site_scripting_vulnerability_test/

NOTE: This issue was originally not considered a vulnerability by the
researcher and vendor due to the fact that no known vectors existed to
exploit it. However, additional research by Amit Klein has proven that
this can be exploited via a specially crafted Flash file.

SOLUTION:
Update to version 1.3.35, 2.0.58, 2.2.2, or later.

PROVIDED AND/OR DISCOVERED BY:
Thiago Zaninotti
