Background
xchat is an IRC (Internet Relay Chat) client that allows users to connect to IRC servers and participate in chat rooms. It provides a graphical user interface and supports various features such as multiple server connections, customizable themes, and scripting capabilities. However, a directory traversal vulnerability was discovered in xchat, which could be exploited by remote IRC servers to read or modify arbitrary files on the client system.
