NetScreen ScreenOS before 2.6.1 does not support a maximum number of concurrent sessions for a system, which allows an attacker on the trusted network to cause a denial of service (resource exhaustion) via a port scan to an external network, which consumes all available connections.

Security readout for executives and security teams

This old ScreenOS issue can let someone already on the trusted internal network exhaust firewall session resources, causing denial of service for traffic through the device. The business impact is availability loss, not confirmed data theft. Public sources do not show active exploitation or CISA KEV listing. Exposure is most likely limited to legacy NetScreen devices running ScreenOS before 2.6.1, especially where many trusted-network users or compromised internal hosts can initiate outbound connections through the firewall. Prioritize if legacy NetScreen firewalls still protect business-critical network paths. For organizations without ScreenOS before 2.6.1, this is mainly a historical tracking item. The main risk is localized outage from an internal or compromised trusted host. Mitigation focus: Inventory NetScreen ScreenOS versions and identify systems older than 2.6.1.; Review historical NetScreen or successor vendor guidance for supported upgrade paths.; Upgrade affected ScreenOS systems to 2.6.1 or later where feasible..
