Open WebMail 1.71 "background" magic info

["FreeBSDbr Bugtraq DataBase" <db-bugtraq () freebsdbr com br>]

Hello Folks,

Open Webmail is a perl webmail program that runs on UNIX operational systems. 
For more about Open WebMail, it´s official website is http://openwebmail.org/.

Ok, let´s talk about the problem.

I´ve tested Open WebMail 1.71 an when you enter an invalid username (user 
that doesn´t exist on the system), the 
WebMail returns to you a "very nice screen" like it:

---
Open WebMail ERROR 

user does not exist 

Open WebMail version 1.71 
---

Ok, now try to copy with your mouse the all message that returned to you, 
and...

---
Open WebMail ERROR 

user does not exist 
euid=0, egid=80 80 80, mailgid=6 

Open WebMail version 1.71 
---

...KABOOM! Look what magically appears:

"euid=0, egid=80 80 80, mailgid=6"

allright, let´s verify the information:

ps aux
root        9044  0.0  3.0  3248 2776  ??  R    10:29AM   
0:00.40 /usr/bin/perl -T /usr/local/www/cgi-bin/openwebmail/.openwebmail.pl

As you can see above, the perl scrip run as root, and we can know it just 
with the "magically information" that appears on the "very nice screen".

That´s could be the begin for an attack... know information. 

Yeah guys, something is wrong... Some information is better than we can 
imagine, and some information like it to the wrong (or right) guys... :)

Hugs,
