The remote host is missing an update to the system as announced in the referenced advisory.

Update your system with the appropriate patches or software upgrades. http://www.apache-ssl.org/advisory-20040206.txt http://www.vuxml.org/freebsd/7557a2b1-5d63-11d8-80e3-0020ed76ef5a.html

The following package is affected: apache+ssl If configured with SSLVerifyClient set to 1 or 3 (client certificates optional) and SSLFakeBasicAuth, Apache-SSL 1.3.28+1.52 and all earlier versions would permit a client to use real basic authentication to forge a client certificate. All the attacker needed is the 'one-line DN' of a valid user, as used by faked basic auth in Apache-SSL, and the fixed password ('password' by default).
