CVE-2004-0605: n/a vulnerability

CVE-2004-0605: Non-registered IRC users using (1) ircd-hybrid 7.0.1 and earlier, (2) ircd-ratbox 1.5.1 and earlier, or (3)...

Non-registered IRC users using (1) ircd-hybrid 7.0.1 and earlier, (2) ircd-ratbox 1.5.1 and earlier, or (3) ircd-ratbox 2.0rc6 and earlier do not have a rate-limit imposed, which could allow remote attackers to cause a denial of service by repeatedly making requests, which are slowly dequeued.

Security readout for executives and security teams

This is a denial-of-service issue in older ircd-hybrid and ircd-ratbox IRC servers. Unregistered users were not rate-limited, allowing remote unauthenticated users to disrupt service by creating request backlog pressure. The documented impact is IRC availability loss, not data theft or system takeover. Exposure is likely limited to organizations still running the named legacy IRC daemon versions, especially internet-facing IRC servers accepting unauthenticated connections. Modern deployments or unrelated IRC software are not evidenced as affected in the supplied sources. Handle as a targeted legacy exposure issue. It warrants prompt attention if the business still operates public IRC infrastructure, but the supplied evidence does not support emergency treatment across normal enterprise systems. Mitigation focus: Inventory IRC servers for the named ircd-hybrid and ircd-ratbox versions.; Check current vendor or project guidance for fixed releases or recommended configuration changes.; Prioritize replacement or upgrade of affected legacy IRC daemons where found..
