What is CVE-2018-16495?

In the VOS application, the user session identifier is issued prior to authentication and remains unchanged after a successful user login. This design flaw allows an attacker to exploit the session management process by establishing a trap session on the victim's device. Once the victim logs in, the attacker can hijack the session, potentially gaining unauthorized access to sensitive information. It emphasizes the critical need for robust session management protocols to mitigate the risks associated with this vulnerability.
