Comment 6 Vincent Danen 2012-08-08 20:26:04 UTC 
Condor installations that rely solely upon host-based authentication are vulnerable to an attacker who controls an IP, its reverse-DNS entry and has knowledge of a target site's security configuration. With this control and knowledge, the attacker can bypass the target site's host-based authentication and be authorized to perform privileged actions (i.e. actions requiring ALLOW_ADMINISTRATOR or ALLOW_WRITE). Condor deployments using host-based authentication that contain no hostnames (IPs or IP globs only) or use authentication stronger than host-based are not vulnerable.
