CVE-2013-3066: Linksys EA6500 with firmware 1.1.28.147876 does not properly restrict access, which allows remote attackers...

Security readout for executives and security teams

This issue affects Linksys EA6500 routers running firmware 1.1.28.147876. The router may expose client and configuration information through the /JNAP/ interface because access is not properly restricted. That information can help an attacker understand the network and plan follow-on activity. Exposure is most likely where Linksys EA6500 routers on firmware 1.1.28.147876 allow /JNAP/ access from untrusted networks, including internet-facing management paths or hostile LAN segments. Treat this as a targeted remediation item for legacy router exposure. The business risk is sensitive network information disclosure, especially if affected routers are reachable from untrusted networks. Prioritize inventory, exposure reduction, and vendor guidance review. Mitigation focus: Inventory Linksys EA6500 routers and confirm firmware versions.; Restrict router management and JNAP access to trusted networks only.; Check Linksys or vendor guidance for fixed firmware or replacement options..
