RapidStream VPN nodes has hard-coded the 'rsadmin' account into the sshd binary in the appliance OS. The account has been given a 'null' password in which password assignment and authentication was expected to be handled by the RapidStream software itself. The vendor failed to realize that arbitrary commands could be appended to the ssh string when connecting to the SSH server on the remote vpn. This in effect could lead to many things, including the ability to spawn a remote root shell on the vpn.

It is updated regularly and scans for just about all remotely detectable vulnerabilities. Features include scanning through a firewall, updated security checks from CERT & CIAC bulletins, 4 levels of severity (red, yellow, brown, & green) and a feature rich HTML interface.

2e6466d6e3dddc4f8a9cbd550dc4bdf278548f173b6f6f055ed30ebfbff8d7b9FakeGINA intercepts the communication between Winlogon and the normal GINA, and while doing this it captures all successful logins (domain, username, password) and writes them to a text file. FakeGINA shows at least one very important thing - one should never use the same password on more than one system. If one system is compromised, the attacker might use something like FakeGINA to capture all the passwords, and then use them against other systems.

7c0acd2703b07ca2be23cdd13d8a4ddc0d3ffedbcef8d1fe088ffb25c5bec951FreeBSD Security Advisory FreeBSD-SA-00:35 - The proftpd port, versions prior to 1.2.0rc2, contains a vulnerability which allows FTP users, both anonymous FTP users and those with a valid account, to execute arbitrary code as root on the local machine, by inserting string-formatting operators into command input, which are incorrectly parsed by the FTP server.
76f84091c90af96f01cf6608f849ae0a2517b33712ed0dccad709b014fd49f84FreeBSD Security Advisory FreeBSD-SA-00:34 - ISC-DHCP is an implementation of the DHCP protocol containing client and server. FreeBSD 3.2 and above includes the version 2 client by default in the base system, and the version 2 and version 3 clients and servers in the Ports Collection. The dhclient utility (DHCP client), versions 2.0pl2 and before (for the version 2.x series), and versions 3.0b1pl16 and before (for the version 3.x series) does not correctly validate input from the server, allowing a malicious DHCP server to execute arbitrary commands as root on the client. DHCP may be enabled if your system was initially configured from a DHCP server at install-time, or if you have specifically enabled it after installation. FreeBSD 4.1 is not affected by this problem since it contains the 2.0pl3 client.
