Fedora 10: FEDORA-2009-2805 Moderate: Ntop Access Log Issue

Fixed log world-writable when the --access-log-file option is used.. --------------------------------------------------------------------------------Fedora Update Notification FEDORA-2009-2805 2009-03-18 18:32:58 --------------------------------------------------------------------------------Name : ntop Product : Fedora 10 Version : 3.3.8 Release : 3.fc10 URL : https://www.ntop.org/ Summary : A network traffic probe similar to the UNIX top command Description : ntop is a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntop is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform and on Win32 as well. ntop users can use a a web browser (e.g. netscape) to navigate through ntop (that acts as a web server) traffic information and get a dump of the network status. In the latter case, ntop can be seen as a simple RMON-like agent with an embedded web interface. The use of: * a web interface * limited configuration and administration via the web interface * reduced CPU and memory usage (they vary according to network size and traffic) make ntop easy to use and suitable for monitoring various kind of networks. ntop should be manually started the first time so that the administrator password can be selected. --------------------------------------------------------------------------------Update Information: ls -lh /var/log/ntop/access.log -rw-rw-rw- 1 root root 0 2009-02-04 11:53 /var/log/ntop/access.log Fixed. log world-writable when the --access-log-file option is used. This option is not used in Fedora or Red Hat by default and is not noted in the configuration file. It is, however, noted in the ntop manpage. It would require the root user to add this option to the configuration in order for this file to be created. --------------------------------------------------------------------------------ChangeLog: *Tue Mar 17 2009 Rakesh Pandit - 3.3.8-3 - Fixed world writable accesslog (#490561) - security bug * Tue Mar 3 2009 Peter Vrabec - 3.3.8-2 - invalid certificate fix (#486725) --------------------------------------------------------------------------------References: [ 1 ] Bug #490561 - ntop: access.log created world-writable https://bugzilla.redhat.com/show_bug.cgi?id=490561 --------------------------------------------------------------------------------This update can be installed with the "yum" update program.

Debian: Serious Access Control Vulnerability in Ntop Exposure Risk

Using ntop to distribute network traffic through the network, it is possible to access arbitrary files on the local filesystem. Since ntop runs as root uid, guess what that means, even /etc/shadow got unsecured.. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ---------------------------------------------------------------------------- Debian Security Advisory This email address is being protected from spambots. You need JavaScript enabled to view it. Debian -- Security Information Martin Schulze August 7, 2000 - ---------------------------------------------------------------------------- Package: ntop Vulnerability: remote file exploit Debian-specific: no Vulnerable: yes Using ntop to distribute network traffic through the network, i.e. running ntop as webserver, it is possible to access arbitrary files on the local filesystem. Since ntop runs as root uid, guess what that means, even /etc/shadow got unsecured. Since ntop comes with its own simple web server this problem is not a result of another webserver insecurity.
