eFiction Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA17777

VERIFY ADVISORY:
http://secunia.com/advisories/17777/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Cross Site Scripting, Manipulation of data, Exposure
of system information, System access

WHERE:
>From remote

SOFTWARE:
eFiction 1.x
http://secunia.com/product/6233/
eFiction 2.x
http://secunia.com/product/6234/

DESCRIPTION:
rgod has reported some vulnerabilities in eFiction, which can be
exploited by malicious people to disclose system information, conduct
cross-site scripting and SQL injection attacks, and compromise a
vulnerable system.

1) Input passed to the "let" parameter in "titles.php" isn't 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.

2) Some input isn't properly sanitised before being used in a SQL
query. This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

3) An input validation error in the "Manage Images" functionality can
be exploited to upload valid images with an arbitrary file extension
inside the web root (e.g. an image with the ".php" file extension
containing embedded PHP code).

Successful exploitation requires that users are allowed to upload
images.

4) The problem is that it is possible to disclose certain system
information by accessing "phpinfo.php".

It is also possible to disclose the full path to "storyblock.php" by
accessing it directly.

The vulnerabilities have been reported in versions 1.0, 1.1, and 2.0.
Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified, restrict access to the  "phpinfo.php" script, and do not
allow users to upload images (this may however affect functionality).
