TITLE:
ProNews Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA23315

VERIFY ADVISORY:
http://secunia.com/advisories/23315/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
ProNews 1.x
http://secunia.com/product/12882/

DESCRIPTION:
Some vulnerabilities have been reported in ProNews, which can be
exploited by malicious people to bypass security restrictions,
conduct SQL injection attacks, and conduct cross-site scripting
attacks.

1) There are insufficient checks within the admin/change.php script
as it does not check if a person has permissions to change news
items.

2) Input passed to the "aa" parameter in lire-avis.php is not
properly sanitised before being used in SQL queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

3) Input passed to the "pseudo", "email", "date", "sujet", "message",
"site" and "lien" parameters in admin/change.php is not properly
sanitised before being stored. This can be exploited to insert
arbitrary HTML and script code, which is executed in a user's browser
session in context of an affected site when the news item is viewed.

4) Input passed to the "aa" parameter in lire-avis.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 reported in version 1.5. Other versions may
also be affected.

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

Restrict access to the admin directory (e.g. with ".htaccess").

PROVIDED AND/OR DISCOVERED BY:
