The Ignition Project Ignitionserver

Unknown vulnerability in The Ignition Project ignitionServer 0.1.2 through 0.3.1, with the linking service enabled, allows remote attackers to bypass authentication.

mod_channel.bas in The Ignition Project ignitionServer 0.3.0 to 0.3.6, and possibly earlier versions, does not properly verify whether a host has the owner privileges required to delete IRC channel access entries, which allows remote attackers to bypass intended restrictions.

The Ignition Project ignitionServer 0.1.2 through 0.1.2-R2 allows remote authenticated users with local IRC operator privileges to obtain global IRC operator privileges by using the unofficial umode command with the +ORD argument.

mod_channel in The Ignition Project ignitionServer 0.3.0 to 0.3.6, and possibly earlier versions, does not allow protected operators to access channels that have been locked out by a key, which allows IRC users to cause a denial of service.
