Just to make sure I'm getting it right:

We should use phpmail or SMTP, BUT NOT sendmail?

I'm about 99% sure that that's the point, but perhaps I'm getting lost in translation here.

to fix this issue:

open class/mail/phpmailer/class.phpmailer.php

find on line 391 (xoops 2.0.16)

if ($this->Sender != "")
            
$sendmail sprintf("%s -oi -f %s -t"$this->Sendmail$this->Sender);
        else
            
$sendmail sprintf("%s -oi -t"$this->Sendmail);


REPLACE with:

if ($this->Sender != "")
        {
            
$sendmail sprintf("%s -oi -f %s -t"escapeshellcmd($this->Sendmail), escapeshellarg($this->Sender));
        } else {
            
$sendmail sprintf("%s -oi -t"escapeshellcmd($this->Sendmail));
        }


voila! now you can use sendmail again safeley :)

i didn't discover the solution.

I got the solution from phpmailer project site, and simply edited the XOOPS class file with their fix..

have submitted it to sf patches tracker.

Double or triple thanks, Vaughn. Around line 590 for XOOPS 2.2.

Why (oh why... ) can we not have a 'security notices' forum like virtually every other CMS community has?.

Then valuable fixes like Vaughn's and the advice in this thread about protecting the XOOPS upload folder could be posted for all to see, not just those that discover these solutions by accident.
A thread is for life. Not just for Christmas.

vaughan, why is $this->Sendmail escaped, since its value is set in the script, and not from user input?
