What is CVE-2019-8978?

An improper authentication vulnerability present in Ellucian Banner Web Tailor and Banner Enterprise Identity Services can be exploited via a race condition. Attackers can remotely compromise a victim's session and potentially cause a denial of service. By repeatedly accessing the initial login page with a crafted IDMSESSID cookie aligned with the victim's institutional ID, attackers can leverage the race condition to receive the session ID intended for the victim, thereby gaining unauthorized access.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
