Subject: VICIDIAL 2.7 - SQL Injection, Command Injection
Requestor: Adam Caudill, adam@...mcaudill.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='$server_ip';";
manager_send.php:429
passthru("/usr/local/bin/sipsak -M -O desktop -B \"$SIPSAK_prefix$campaign\" -r 5060 -s sip:$extension@...one_ip > /dev/null");
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.
