TITLE:
logahead UNU edition Security Bypass and File Upload

SECUNIA ADVISORY ID:

http://secunia.com/advisories/23470/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, System access

WHERE:
>From remote

SOFTWARE:
logahead UNU edition
http://secunia.com/product/12977/

DESCRIPTION:
CorryL has reported two vulnerabilities in logahead UNU edition,
which can be exploited by malicious people to bypass certain security
restrictions and compromise vulnerable systems.

1) The bypass vulnerability is caused due to an error in the
extras/plugins/widged/_widged.php script, which allows
unauthenticated people to upload files to the server.

2) The extras/plugins/widged/_widged.php script fails to validate the
extension of an uploaded file. This can be exploited to upload files
with arbitrary extensions (e.g. ".php") and execute arbitrary PHP
code on the server.

The vulnerabilities are reported in version final.01 downloaded
before 2006-12-26. Prior versions may also be affected.

SOLUTION:
Vulnerability #1 is fixed in version final.01 released on 2006-12-26.

PROVIDED AND/OR DISCOVERED BY:
CorryL
