CRITICAL:
Highly critical

IMPACT:
Manipulation of data, System access

WHERE:

SOFTWARE:
RechnungsZentrale V2

DESCRIPTION:
GroundZero Security Research has discovered some vulnerabilities in
RechnungsZentrale V2, which can be exploited by malicious people to
conduct SQL injection attacks and compromise a vulnerable system.

1) Input passed to the "user" parameter in mod/authent.php4 is not
properly sanitised before being used in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "rootpath" parameter in mod/authent.php4 is
not properly verified before being used to include files. This can be
exploited to execute arbitrary PHP code by including PHP files from
local or external resources.

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

The vulnerabilities have been confirmed in version 1.1.3. Other
versions may also be affected.

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