Technical details
The labeled-response module in UnrealIRCd 6.0.0 before 6.2.7.1 fails to escape the IRCv3 "label" message tag when echoing it into server replies, enabling injection of server-to-server commands. An attacker on a linked server can craft a malicious label tag that breaks out of the reply context and injects arbitrary commands executed with server authority, bypassing normal access controls.
