Apparently I was wrong about "a vulernability is being exploited on the top-level script." Criss, who helped me upgrade to the latest version of PmWiki, tells me:

The way the mailform works, people *can't* get your email address. Your email address is in the config file, not anywhere a spammer
   could get to it.

But after the upgrade, I'm still getting about 15 spams each day. Here's an example:

<a href="http://www.spazioforum.it/forums/cayman.html";>viagra online</a> [url=http://www.spazioforum.it/forums/cayman.html]viagra online[/url] <a href="http://www.spazioforum.it/forums/gtcup.html";>buy levitra</a> [url=http://www.spazioforum.it/forums/gtcup.html]buy levitra[/url] <a href="http://www.spazioforum.it/forums/carrera.html";>viagra cheap</a> [url=http://www.spazioforum.it/forums/carrera.html]viagra cheap[/url] <a href="http://www.spazioforum.it/forums/cayenne.html";>buy generic viagra</a> [url=http://www.spazioforum.it/forums/cayenne.html]buy generic viagra[/url] <a href="http://www.spazioforum.it/forums/boxster.html";>generic cialis</a> [url=http://www.spazioforum.it/forums/boxster.html]generic cialis[/url] cnk7inl180cn9n9 -------------------------------------------/*

But http://progressiveresourcecatalog.org/index.php/Comment.MailformWh no longer exists. I deleted it and substituted "To contact the Progressive Resource Catalog, send email to Wade Hudson, whudson AT igc DOT org." (See http://progressiveresourcecatalog.org/index.php/Comment.Home). How can I be getting spam from a mailform that is no longer on my site?

Using Thunderbird, I filter that spam into my Junk mail folder and periodically delete them. So it's no real problem for me and my web host no longer seems worried about a more serious vulnerability.

But this spam remains a curiosity that may be of interest to others and may be a problem that we can solve somehow. Could the spammers have captured what they need to use the mail form even though that page is no longer on the site?

Should I update my comments.php or my mailform recipe (they're both old)?

Thanks,
Wade

Dear pmwiki users:

On my site, a vulernability is being exploited on the top-level script. About ten times a day, I receive spam that includes a number as the username and then has "@users.hostname.net" as the domain name.


I'm not to clear on the details here. Are you saying that pmwiki.php is being used to send spam?
