Vulnerability Summary for CVE-2007-4465

Original release date: 09/13/2007
Last revised: 03/07/2011


Cross-site scripting (XSS) vulnerability in mod_autoindex.c in the Apache HTTP Server before 2.2.6, when the charset on a server-generated page is not defined, allows remote attackers to inject arbitrary web script or HTML via the P parameter using the UTF-7 charset. NOTE: it could be argued that this issue is due to a design limitation of browsers that attempt to perform automatic content type detection.


CVSS Severity (version 2.0):
CVSS v2 Base Score: 4.3 (MEDIUM) (AV:N/AC:M/Au:N/C:N/I:P/A:N) (legend)
Impact Subscore: 2.9
Exploitability Subscore: 8.6
CVSS Version 2 Metrics:
Access Vector: Network exploitable
Access Complexity: Medium
Authentication: Not required to exploit
Impact Type: Allows unauthorized modification

Vendor Statements (disclaimer)

Official Statement from Red Hat (09/18/2007)
This is actually a flaw in browsers that do not derive the response character set as required by RFC 2616. This does not affect the default configuration of Apache httpd in Red Hat products and will only affect customers who have removed the "AddDefaultCharset" directive and are using directory indexes. The Red Hat Security Response Team has rated this issue as having low security impact, a future update may address this flaw. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=CVE-2007-4465
Official Statement from Apache (09/14/2007)
The Apache security team believe that this issue is due to web browsers that are violating RFC2616. However, Apache 2.2.6 and 2.0.61 add a workaround for such browsers by adding Type and Charset options to IndexOptions directive. This allows a site administrator to explicitly set the content-type and charset of the generated directory index page.
