TITLE:
HotNews Arbitrary File Inclusion Vulnerability

SECUNIA ADVISORY ID:
SA10551

VERIFY ADVISORY:
http://www.secunia.com/advisories/10551/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
From remote

SOFTWARE:
HotNews 0.x

DESCRIPTION:
Officerrr has identified a vulnerability in HotNews, allowing
malicious people to compromise a vulnerable system.

The problem is that the include files "hnmain.inc.php3" and
"hotnews-engine.inc.php3" don't verify the "config["header"]" and
"config["incdir"]" parameters properly. This can be exploited to
include arbitrary PHP code from local and external resources.

The vulnerability has been confirmed in 0.7.2. Prior versions may
also be affected.

SOLUTION:
Protect the "includes" directory with .htaccess or similar.

Edit the source code to ensure that input is properly verified or
paths to include files are set to fixed values.
