- An improper privilege management vulnerability [CWE-269] in Fortinet FortiOS version 7.2.0 and before 7.0.7 and FortiProxy version 7.2.0 through 7.2.1 and before 7.0.7 allows an attacker that has access to the admin profile section (System subsection Administrator Users) to modify their own profile and upgrade their privileges to Read Write via CLI or GUI commands.
