Description |
Microsft Windows contains a flaw that may allow a remote attacker to bypass the IPSEC filter by using port 88. The issue is due to the IPSEC filter having a default exemption to the Kerberos port(88). It is possible that the flaw may allow a remote attacker to gain unauthorized network access resulting in a loss of integrity.
