If you ran the (fortunately non-default) http-domino-enum-passwords script with the (fortunately also non-default) domino-enum-passwords.idpath parameter against a malicious server, it could cause an arbitrarily named file to to be written to the client system. Thanks to Trustwave researcher Piotr Duszynski for discovering and reporting the problem. We've fixed that script, and also updated several other scripts to use a new stdnse.filename_escape function for extra safety. This breaks our record of never having a vulnerability in the 16 years that Nmap has existed, but that's still a fairly good run. [David, Fyodor]

Discovers hostnames that resolve to the target's IP address by querying the online database at http://www.bfk.de/bfk_dnslogger.html.

The script is in the "external" category because it sends target IPs to a third party in order to query their database.

This script was formerly (until April 2012) known as hostmap.nse.
