<mailto:adam () adamcaudill com> Software: VICIDIAL
(http://www.vicidial.org/vicidial.php) Vendor: The Vicidial Group
(http://www.vicidial.com/) Vulnerability Type: Authenticated SQL
Injection, Authenticated Command Injection

Source Code:
http://sourceforge.net/projects/astguiclient/files/astguiclient_2.7rc1.zip/download


Flaws exist in /www/agc/manager_send.php
SQL Injection: Line 285 Command Injection: Line 429

Affected Versions: 2.7RC1, 2.7, 2.8-403a (others likely)

Current released version is vulnerable; vendor confirmed issue on
6/3, set timeline for mid-July release, has delayed continually.
Vendor has deployed fixes to users of their hosted service, still
no updates or advisory for OSS users.

Affected lines of code:

manager_send.php:285 $stmt="SELECT count(*) from
web_client_sessions where session_name='$session_name' and
server_ip='$server_ip';";

Please use CVE-2013-4467 for the SQL injection

manager_send.php:429 passthru("/usr/local/bin/sipsak -M -O desktop
-B \"$SIPSAK_prefix$campaign\" -r 5060 -s sip:$extension () $phone_ip
/dev/null");


Please use CVE-2013-4468 for the command injection

In both of these cases, parameters are passed through without
validation or escaping.

During setup, two accounts with hard-coded passwords are created
(VDAD, VDCL), these can be used to bypass the authentication check,
allowing access to where the SQL Injection vulnerability is, which
can be used to bypass an additional check, thus giving access to
the Command Injection vulnerability. The output from shell commands
are returned in the server response.

There are MANY other issues of various types in this software, but
I am not documenting them.

Security vulns rarely come alone or just in pairs, usually they travel
in packs :P.
