Executive Summary

This vulnerability in FortiIsolator versions 2.0 through 2.4.4 involves insufficient session expiration and incorrect authorization in the authentication mechanism. It allows a remote unauthenticated attacker to deauthenticate logged-in administrators by using a crafted cookie. Additionally, a remote authenticated attacker with read-only privileges can escalate their privileges to write access by exploiting the same crafted cookie vulnerability.

Impact Analysis

The vulnerability can impact you by allowing attackers to forcibly log out administrators, disrupting management and potentially causing denial of service. Moreover, attackers with limited read-only access can gain write privileges, which could lead to unauthorized changes, data manipulation, or further compromise of the system.
