CVE-2018-16495
Failing to issue a new session ID following a successful login introduces the possibility for an attacker to set up a trap session on the device the victim is likely to login with.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.91%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In VOS user session identifier (authentication token) is issued to the browser prior to authentication but is not changed after the user successfully logs into the application. Failing to issue a new session ID following a successful login introduces the possibility for an attacker to set up a trap session on the device the victim is likely to login with.
