Subject: remote root exec vulnerability in omail

product:omail webmail
version: 0.98.5
notified: now


the "patch" on omail.pl still leaves the system wide open for attack,

the regex to filter out " and ' doesn't help you much if your $SHELL is bash
or something similar

both back ticks and more arcane ways of shell expansion $(rm -rf /) are
still possible

fix it by replacing the regex around line 411 to something like


        $password = quotemeta($password);
        

Happy patching,

Thijs
