Short explanation

The labeled-response module in UnrealIRCd 6.0.0 through 6.2.7.1 does not escape the IRCv3 label message tag when echoing it into replies, allowing any user on a network with two or more linked servers to inject server-to-server commands executed with server authority (S0).

Why does it matter?

This vulnerability poses a high risk to integrity because it allows unauthenticated network users to inject server-to-server commands that execute with server authority (S0).
