Strange you should mention this.
A friend of mine was telling me that there is a commonly
used cgi tool that is used on many hosts to permit
folks on the web to send feedback mail.
It has the apparent advanatage that it does not disclose the
address of the account the mail is being sent to.
It also has a bug.
The bug permits a remote user to craft a html URL which
corrupts the sender address and sends mail out.
Thus a script can bang through a pile of addresses and
spam the world. It is as bad as an open relay but
it is this common chunk of cgi code.
Apparently there are multiple versions that are vulnerable.
I am now looking for a mailing list for web manager
where I can track such stuff.
Scan your logs.....
