A vulnerability exists in versions 1.4.2 and earlier of the X-Chat IRC client. By supplying commands enclosed in backticks (``) in URL's sent to X-Chat, it is possible to execute arbitrary commands should the X-Chat user decide to view the link by clicking on it. This is due to the manner in which X-Chat launches pages for viewing.

X-Chat launches Netscape without checking for shell metacharacters in the supplied URL. This allows for an attacker to exploit shell expansion capabilities to execute commands as the user running Netscape.
