CVE-2011-1323: n/a vulnerability

CVE-2011-1323: Yamaha RTX, RT, SRT, RTV, RTW, and RTA series routers with firmware 6.x through 10.x, and NEC IP38X series...

Yamaha RTX, RT, SRT, RTV, RTW, and RTA series routers with firmware 6.x through 10.x, and NEC IP38X series routers with firmware 6.x through 10.x, do not properly handle IP header options, which allows remote attackers to cause a denial of service (device reboot) via a crafted option that triggers access to an invalid memory location.

Security readout for executives and security teams

This CVE describes a crash condition in certain Yamaha and NEC router firmware. A remote attacker could send a crafted network packet using IP header options and cause the device to reboot, interrupting connectivity. The provided sources do not include a CVSS score or confirm active exploitation. Exposure is most relevant where affected routers are still deployed and reachable from untrusted networks. The source bundle does not provide product-specific fixed versions, deployment prevalence, or internet exposure data. Treat as an availability risk for legacy network infrastructure. Escalate if affected routers support critical sites, branch connectivity, or customer-facing services, especially if exposed to untrusted traffic. Mitigation focus: Inventory Yamaha and NEC router models and firmware versions.; Check the Yamaha, NEC, and JVN advisories for fixed firmware or vendor workarounds.; Prioritize affected edge or internet-reachable routers for remediation..
