CVE-2002-1236: The remote management web server for Linksys BEFSR41 EtherFast Cable/DSL Router before firmware 1.42.7 allo...

Security readout for executives and security teams

This is a legacy denial-of-service issue in the Linksys BEFSR41 router’s remote management web server. A malformed HTTP request can crash the device, interrupting connectivity or administration. Sources identify firmware before 1.42.7 as affected, but provide no CVSS score or active exploitation evidence. Exposure is most relevant where legacy BEFSR41 routers remain deployed and their management web interface is reachable from untrusted networks. Internet-exposed remote management would raise urgency. Modern environments are unlikely to run this device, but embedded and forgotten edge equipment should be checked. Prioritize remediation if any affected router still supports business connectivity or has exposed management access. For most organizations this is a legacy asset discovery and replacement issue, not a broad emergency, because evidence of active exploitation is not provided. Mitigation focus: Upgrade affected BEFSR41 firmware to version 1.42.7 or later where available.; Disable remote management if it is not operationally required.; Restrict management access to trusted administrative networks only..
