CVE-2007-4789: Cisco Content Switching Modules (CSM) 4.2 before 4.2.7, and Cisco Content Switching Module with SSL (CSM-S)...

Security readout for executives and security teams

This is an older Cisco load-balancing module flaw that can let a remote attacker cause the device to reboot when service termination is enabled and network utilization is high. The business impact is service interruption, not data theft. Exposure is mainly relevant where affected Cisco CSM or CSM-S modules remain in production. Likely exposure is limited to environments still running affected Cisco Content Switching Module or CSM-S software, especially on reachable traffic paths with service termination enabled. The bundle does not provide CPEs or modern deployment prevalence. Treat this as a targeted availability risk for legacy network infrastructure. Prioritize if affected modules sit on critical application paths, internet-facing paths, or high-volume traffic segments. Otherwise, fold into legacy platform remediation and retirement planning. Mitigation focus: Identify any Cisco CSM or CSM-S modules still deployed.; Upgrade CSM 4.2 deployments to 4.2.7 or later.; Upgrade CSM-S 2.1 deployments to 2.1.6 or later..
