VAR-200108-0113
Vulnerability from variot - Updated: 2023-12-18 13:58NetScreen ScreenOS prior to 2.5r6 on the NetScreen-10 and Netscreen-100 can allow a local attacker to bypass the DMZ 'denial' policy via specific traffic patterns. NetScreen is a line of internet security appliances inetgrating firewall, VPN and traffic management features. Versions of ScreenOS, the inbuild OS of two models in the NetScreen line (NetScreen-10 & -100) contain a flaw which may permit some packets, of a type which has been denied, to enter the DMZ. As a result of this vulnerability, potentially malicious packets of a type which has been prohibited in the device's policy may, to a limited extent, reach the DMZ network. Further details of this vulnerability were not made available. Versions prior to NetScreen ScreenOS 2.5r6 on NetScreen-10 and Netscreen-100 are vulnerable
