Description
BullWall Server Intrusion Protection services are initialized after login services. An authenticated attacker with administrative permissions can log in after boot and bypass MFA. SIP service does not retroactively enforce the challenge or disconnect unauthenticated sessions.

Executive Summary

This vulnerability occurs in BullWall Server Intrusion Protection services where the protection services are initialized only after login services. An attacker who is authenticated and has administrative permissions can log in after the system boots and bypass multi-factor authentication (MFA). Additionally, the SIP service does not enforce MFA challenges retroactively or disconnect sessions that are unauthenticated, allowing the attacker to maintain access without completing MFA.

Impact Analysis

This vulnerability can allow an attacker with administrative permissions to bypass MFA, potentially gaining unauthorized access to the system even after boot. This could lead to unauthorized control, data compromise, or disruption of services, as the attacker can maintain access without proper authentication enforcement.
