CVE-2017-14219: XSS (persistent) on the Intelbras Wireless N 150Mbps router with firmware WRN 240 allows attackers to steal...

Security readout for executives and security teams

This CVE describes a persistent cross-site scripting flaw in Intelbras Wireless N 150Mbps WRN 240 routers. A nearby attacker could advertise a malicious Wi-Fi network name that the router interface later displays, potentially stealing wireless credentials from an administrator without already joining the network. Exposure is most likely where Intelbras WRN 240 routers are still deployed and administrators use the affected web interface near untrusted wireless signals. The source bundle does not establish other Intelbras models or firmware versions as affected. Treat this as a targeted legacy-router risk. It is not documented here as actively exploited, but it can expose Wi-Fi credentials and may justify replacement where the model remains in business use. Mitigation focus: Check Intelbras guidance for firmware updates or retirement advice.; Replace affected routers if no supported firmware is available.; Restrict router administration to trusted operators and locations..
