Service: Webmail Perl Client
Vendor: neomail / www.neocodesolutions.com
Vulnerability: Cross Site Scripting / Cookie-Theft / Relogin attacks
Severity: Medium/High
Details:
NeoMail is a free open-source perl web-based e-mail client that can be
installed on any UNIX mail server that is also running a web server. With
thousands of installations worldwide, neomail has many features like
Sending/receiving messages with multiple attachments, inline image
attachment display Friendly, attractive, icon-based user interface,
multiple language support, including English, Spanish, German, French,
Hungarian, Italian, Dutch, Polish, Portuguese, Norwegian, Romanian,
Russian, Slovak, and more can be added easily ... configurable limits on
outgoing attachment size, folder disk usage, addressbook size... users can
import their address book from Outlook Express or Netscape Mail in CSV
format and more. neomail.pl is prone to cross-site scripting attacks. This
problem is due to a failure in the script to properly sanitize
user-supplied input. input can be passed in variable $date
Impact:
an attacker can exploit the vulnerable scripts to have arbitrary script
code executed in the browser of an authentified
neomail user in the context of the vulnerable website. resulting in the
theft of cookie-based authentication giving the
attacker full access to the victim's neomail email account as well as
other type of attacks.
Affected script with proof of concept exploit:
/neomail.pl?sessionid=XXXX-session-0.9565905XXXXXXXX&sort=date"><script>alert('vul')</script>&folder&action=displayheaders&firstmessage=1
Examples:
http://www.vulnerable-site.com/neomail.pl?sessionid=XXXX-session-0.9565905XXXXXXXX&sort=date"><script>alert('vul')</script>&folder=&action=displayheaders&firstmessage=1
