TITLE:
MaxWebPortal Cross-Site Scripting and SQL Injection

SECUNIA ADVISORY ID:
SA15329

VERIFY ADVISORY:
http://secunia.com/advisories/15329/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
MaxWebPortal 1.x
http://secunia.com/product/1667/

DESCRIPTION:
Zinho has reported some vulnerabilities in MaxWebPortal, which can be
exploited by malicious people to conduct cross-site scripting and SQL
injection attacks.

1) Input passed to the "mod", "M" and "type" parameters in "post.asp"
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 a vulnerable site.

2) Input passed to the "Forum_Title" parameter in "post.asp" is not
properly sanitised before being used. This can be exploited to inject
arbitrary HTML and script code, which will be executed in a user's
browser session in context of an affected site when the malicious
user data is viewed.

3) Input passed to the "txtAddress", "message" and "subject"
parameters in "post_info.asp", the "andor" parameter in "search.asp",
the "verkey" parameter in "pop_profile.asp", a certain password
parameter in "pop_profile.asp", and the "Remove" and "Delete"
parameters in "pm_delete2.asp" isn't properly sanitised before being
used in a SQL query. This can be exploited to manipulate SQL queries
by injecting arbitrary SQL code.

The vulnerabilities have been reported in version 1.3.5 and prior.
Other versions may also be affected.

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