-------------------
-------------------

"POST-ITS" ISSUE:

-------------------
-------------------



When a user, teacher, admin, alumn, post a new post-its,
he could read all post-its in database.

The vuln link would be:

http://[HOST]/[PATH]/ilias.php?col_side=right&block_type=pdnotes&rel_obj=0&note_id=1&note_type=1&cmd=showNote&cmdClass=ilpdnotesblockgui&cmdNode=50&baseClass=ilPersonalDesktopGUI


Changing note_id=1 for other value, for ex. 100, we could
read this posts-it.

That seems a low risk vuln but, when i tested on-line, ie,
against my university and i've got a lot of sensitive information.



-------------------
-------------------

"CMD" ISSUE:

-------------------
-------------------



Course/group/... calendars:

This would be a normal link:


http://[HOST]/[PATH]/repository.php?cmd=frameset&ref_id=50438


But if I change cmd=frameset for cmd=edit:


http://[HOST]/[PATH]/repository.php?ref_id=50438&cmd=edit


I access to information about this group/course/..., and I tried to
change it, but i got permission denied...anyway, i
can get how it's configured this group/course/...



-------------------
-------------------

"CALENDAR" ISSUE:

-------------------
-------------------



http://[HOST]/[PATH]/ilias.php?seed=2009-06-28&category_id=847&calendar_mode=2&cmd=edit&cmdClass=ilcalendarcategorygui&cmdNode=6&baseClass=ilPersonalDesktopGUI


Changing category_id, it shows sensitive information about
any course/group/...

Personal and global calendars are secure.

This module (favorite) allows to get a repository of favorite links



-------------------
-------------------

"FAVORITE" ISSUE:

-------------------
-------------------


This would be the vuln link:


http://[HOST]/[PATH]/ilias.php?bmf_id=1&obj_id=926&cmd=editFormBookmark&cmdClass=ilbookmarkadministrationgui&cmdNode=2&baseClass=ilPersonalDesktopGUI


GET var 'obj_id' is the vuln var...changing for other value you can view and edit any favorite link.


User (victim) trusts in these links (He posts them)
