TITLE:
ntop Access Log File Insecure Permissions Weakness

SECUNIA ADVISORY ID:
SA34793

VERIFY ADVISORY:
http://secunia.com/advisories/34793/

DESCRIPTION:
A weakness has been reported in ntop, which can be exploited by
malicious, local users to manipulate certain information.

The weakness is caused due to ntop creating the access log file with
world-writable permissions, which can be exploited to modify the
access log information.

Successful exploitation may require that ntop is launched with the
"--access-log-file" and "-d" options.

The weakness is reported in version 3.3.9. Other versions may also be
affected.

SOLUTION:
Fixed in the SVN repository.

PROVIDED AND/OR DISCOVERED BY:
Julien Desfossez
