A session fixation issue was discovered in the NGINX OpenID Connect reference implementation, where a nonce was not checked at login time. This flaw allows an attacker to fix a victim's session to an attacker-controlled account. As a result, although the attacker cannot log in as the victim, they can force the session to associate it with the attacker-controlled account, leading to potential misuse of the victim's session.

NGINX Management Suite default file permissions are set such that an authenticated attacker may be able to modify sensitive files on NGINX Instance Manager and NGINX API Connectivity Manager.   Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

NGINX Management Suite may allow an authenticated attacker to gain access to configuration objects outside of their assigned environment.   Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
