Chamilo LMS version 1.11.10 contains an XSS vulnerability in the personal profile edition form, affecting the user him/herself and social network friends.
A user without privileges in Chamilo LMS 1.11.14 can send an invitation message to another user, e.g., the administrator, through main/social/search.php, main/inc/lib/social.lib.php and steal cookies or execute arbitrary code on the administration side via a stored XSS vulnerability via social network the send invitation feature.
Chamilo LMS 1.11.10 does not properly manage privileges which could allow a user with Sessions administrator privilege to create a new user then use the edit user function to change this new user to administrator privilege.
