TITLE:
Journalness "last_module" PHP Code Execution

SECUNIA ADVISORY ID:
SA28873

VERIFY ADVISORY:
http://secunia.com/advisories/28873/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Journalness 4.x
http://secunia.com/product/17513/

DESCRIPTION:
Iron has discovered a vulnerability in Journalness, which can be
exploited by malicious people to compromise a vulnerable system.

Input passed to the "last_module" parameter in
includes/database/adodb-perf-module.inc.php is not properly sanitised
before being used in a call to "eval()". This can be exploited to
inject and execute arbitrary PHP code via a specially crafted
parameter value.

This is related to:
SA26928

Successful exploitation requires that "register_globals" is enabled,
which is not the recommended setting in the application's installer.

The vulnerability is confirmed in version 4.1. Other versions may
also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
Iron
