"According to the web server banner, the version of mod_ssl running on
the remote host has a cross-site scripting vulnerability. A remote
attacker could exploit this by tricking a user into requesting a
maliciously crafted URL, resulting in stolen credentials.

Note that several Linux distributions (such as RedHat) patched the old
version of this module.  Therefore, this might be a false positive. 
Please check with your vendor to determine if you really are affected by
this flaw.");
