TITLE:
phpSkelSite File Inclusion and Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID:
SA33382

VERIFY ADVISORY:
http://secunia.com/advisories/33382/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting, Exposure of system information, Exposure of
sensitive information, System access

WHERE:
>From remote

SOFTWARE:
phpSkelSite 1.x
http://secunia.com/advisories/product/20917/

DESCRIPTION:
ahmadbady has discovered some vulnerabilities in phpSkelSite, which
can be exploited by malicious people to conduct cross-site scripting
attacks, disclose sensitive information, and compromise a vulnerable
system.

1) Input appended to the URL after "[installation path]/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 the context of an affected site.

2) Input passed to the "TplSuffix" parameter in
skysilver/login.tpl.php is not properly verified before being used to
include files. This can be exploited to include arbitrary files from
local resources via directory traversal attacks.

Successful exploitation of this vulnerability requires that
"register_globals" is enabled.

3) Input passed to the "theme" parameter in skysilver/login.tpl.php
is not properly verified before being used to include files. This can
be exploited to include arbitrary files from local and external
resources via URL-encoded NULL bytes.

Successful exploitation of this vulnerability requires that
"register_globals" is enabled and "magic_quotes_gpc" is disabled.

These vulnerabilities are confirmed in version 1.4. Other versions
may also be affected.

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