TITLE:
SpeedyWiki File Upload And Cross-Site Scripting

SECUNIA ADVISORY ID:
SA22788

VERIFY ADVISORY:
http://secunia.com/advisories/22788/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, System access

WHERE:
>From remote

SOFTWARE:
SpeedyWiki 2.x
http://secunia.com/product/12520/

DESCRIPTION:
Laurent Gaffié and Benjamin Mossé have discovered two vulnerabilities
in SpeedyWiki, which can be exploited by malicious users to compromise
a vulnerable system and by malicious people to conduct cross-site
scripting attacks.

1) The upload.php script fails to validate the extension of an
uploaded file. This can be exploited to upload files with arbitrary
extensions (e.g. ".php") and execute arbitrary PHP code on the
server.

Successful exploitation requires valid user credentials.

2) Input passed to the "showRevisions" parameter in index.php is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

The vulnerabilities are confirmed in version 2.0. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified and
sanitised.
