Auditing for RPC vulnerabilities? Use BASS

BASS includes RPC support, and was designed with bulk in mind (It was developed for the Internet Auditing Project). It will only take a few minutes of trivial effort to update the scanner.

BASS includes RPC support, and was designed with bulk in mind (It was developed for the Internet Auditing Project). It will only take a few minutes of trivial effort to update the scanner (I might just do it myself). Besides being a bit out of date, it's well suited for the task.

RPC support is based on portmapper however, so you won't fair well if the network is behind a firewall.

You can grab it at: http://www.securityfocus.com/data/tools/network/bass-1.0.7.tar.gz

BTW, Unless you're running a Linux libc5 (our original development system), you'll need to apply the bugfix patches posted on Bugtraq a few weeks ago (Yes, a new version *is* in order).

Fyodor's nmap, especially with RPC support is really an excellent tool. However, with nmap:

1) It may take a while to comprehensively scan a very large network.

2) It merely detects the presence of a service, and does not test for vulnerability (by attempting an overflow and evaluating the response, or the lack of one).

Cheers, Liraz
