=========================================================================
= pisg XSS
=========================================================================

pisg is an IRC channel statics generator written in Perl, it creates
statistics from different logfile formats. It was originally written
because IRCStats wasn't open source. So here's an open source/GPL'ed
version to anyone interested. It's a funny thing for your IRC channel,
 and it's highly customizeable.

PROBLEM:
pisg does not sanitize the nick of the user before posting to the web

PROOF:
1. silc
2. /connect silc.net
3. /nick <script>alert(document.domain);</script>
4. /log ...
5. /me a couple of times on a channel
6. /quit
3. then generate stats ./pisg
4. surf the index.html

MORE INFO:
The silc-client, which is an old irssi-client with the silc stuff patched
on, logs in the irssi format which pisg reads, and also silcd allows
strange names like the above "<script>alert(document.domain);</script>".
 But, the major problem is, pisg does not sanitize the nick.  This problem
does not occur when using irssi connected to a regular ircd because the
ircd does not allow the nick.  The "/me <stuff>" is required, a regular
/msg <channel> will
not work.

FIX:
Sanitize everything.

OTHER PROBLEMS:
Could not find a security@...g.net or anything ressembling it.
I can't spell.
This might affect a whole 3 people in the world.
