'This method should return the vulnerability name (as saved in the kb)
to exploit. For example, if the audit.os_commanding plugin finds an vuln
and saves it as:
kb.kb.append( \'os_commanding\' , \'os_commanding\', vuln )
Then the exploit plugin that exploits os_commanding
(attack.os_commanding) should return \'os_commanding\' in this method.'
