CVE-2020-14148Public exploitNetwork attack vector

Remote service crash via prefixless SERVER command

Published Jun 15, 2020 · Updated Aug 4, 2024

Out-of-bounds access in ngIRCd before 26~rc2 allows remote attackers posing as a peer IRC server to crash the service. IRC_SERVER passed an absent Req->prefix to Client_Search instead of rejecting the SERVER command, and a following NJOIN reached an invalid iconv conversion. The path is limited to server-to-server traffic and was demonstrated with iconv enabled; the reported consequence is a process crash.
