3Com OfficeConnect routers using Port Address Translation could allow access to blocked ports
|3com-officeconnect-pat-access (9185)||Medium Risk|
3Com OfficeConnect could allow a remote attacker to bypass access control restrictions and access any port on a computer behind the device, caused by a vulnerability in the Port Address Translation (PAT). If a remote attacker finds a port that is redirected using PAT and connects to this port, the attacker would then be able to connect to any other port behind the router.
No remedy available as of April 1, 2014.
