Condor reverse DNS security bypass
|condor-reverse-dns-security-bypass (77748)||Medium Risk|
Condor could allow an attacker to bypass security restrictions, caused by the improper verification of an IP address when handling reverse DNS lookups of a host name. If host-based authentication is enabled, an attacker with knowledge about the configuration of the target application daemons could exploit this vulnerability via a specially-crafted reverse DNS record to bypass the authentication process to perform unauthorized administrative actions.
Upgrade to the latest version of Condor (7.8.2 or later), available from the Condor Web page. See References.
