TITLE:
Open-Realty "last_module" PHP Code Execution

SECUNIA ADVISORY ID:
SA28874

VERIFY ADVISORY:
http://secunia.com/advisories/28874/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Open-Realty 2.x
http://secunia.com/product/10560/

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

Input passed to the "last_module" parameter in
include/class/adodb/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.

The vulnerability is confirmed in version 2.4.3. Other versions may
also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
Iron
