The application does not generate a new session cookie after the user is logged in. A malicious user is able to create a new session cookie value and inject it to a victim. After the victim logs in, the injected cookie becomes valid, giving the attacker access to the user's account through the active session. ### POC #### Reference - https://n4nj0.github.io/advisories/pi-hole-multiple-vulnerabilities-i/ - https://n4nj0.github.io/advisories/pi-hole-multiple-vulnerabilities-i/ #### Github No PoCs found on GitHub currently.
