SECUNIA ADVISORY ID:
SA19611

VERIFY ADVISORY:
https://secunia.com/advisories/19611/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
Confixx Pro 2
https://secunia.com/product/3175/
Confixx Pro 3
https://secunia.com/product/3174/

DESCRIPTION:
Snake_23 has reported two vulnerabilities in Confixx Pro, which can
be exploited by malicious people to conduct cross-site scripting and
SQL injection attacks.

1) Input passed to the "jahr" parameter in allgemein_transfer.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.

Example:
https://[host]/allgemein_transfer.php?monat=4&jahr=[code]

2) Input passed to the "SID" parameter in index.php 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 3.1.2. Other
versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
Snake_23, LoK-Crew.
