BullWall Server Intrusion Protection (SIP) services are initialized after login services during system startup. A local, authenticated attacker can log in after boot and before SIP MFA is running. The SIP services do not retroactively enforce MFA or disconnect sessions that were not subject to SIP MFA. Versions 4.6.0.0, 4.6.0.6, 4.6.0.7, and 4.6.1.4 are affected. Other versions mayy also be affected. BullWall plans to improve detection method documentation.
Weakness
The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check.
