Access to the device may facilitate malicious cyber adversaries gaining access to the information that flows through the device. Disable SNMP Read/Write if not strictly required, and consider disabling SNMP entirely if it isn't needed. Disable Cisco Smart Install if isn't strictly required. "The feature has been designed for use within the local customer network and should not be exposed to untrusted networks," the company wrote. The ACSC points to Cisco's advice on securely configuring SMI, which was updated in conjunction with their February blog post. The company recommends using newer technology to set up new switches, such as the Cisco Network Plug and Play feature. "Extracted configuration files may contain sensitive information, such as device administrative credentials, and could be used to compromise the router/switch and enable targeting of other devices on the network. Australian organisations have been hit by attackers targeting their Cisco routers and switches and extracting their configuration files, warns the Australian Cyber Security Centre (ACSC). Implement Access Control Lists (ACL) to restrict SNMP access to your network management platform, and configure anti-spoofing at the edge of your network so that spoofed packets claiming to be sent from your network management platform are dropped. "Switches with Cisco Smart Install accessible from the internet, and routers or switches with Simple Network Management Protocol (SNMP) enabled and exposed to the internet, are vulnerable to this activity," they wrote. Cisco has been aware of attackers "potentially abusing the Smart Install (SMI) feature in Cisco IOS and IOS XE Software" since February, they wrote in a blog post at the time, and of attackers actively scanning for networks vulnerable to misuse. Cisco also downplayed the problem in their security advisory of February 14. "Cisco does not consider this a vulnerability in Cisco IOS, IOS XE, or the Smart Install feature itself but a misuse of the Smart Install protocol, which does not require... Source: www.zdnet.com
The BoltMAR 20-11 is further equipped with a 50-channel GPS receiver with -160 dBm sensitivity. The system also provides 2x optoisolated DIO interfaces, plus an odometer and Key-IN connection. Bluetooth with BLE is a “consult factory” option, and Eurotech can also provide more extensive customizations. It occurs to us that Eurotech’s BoltMAR 20-11 might come in very handy in such a situation. It also provides QoS and traffic shaping, authentication, encryption security, and IOS management features. More information may be found on Eurotech’s BoltMAR 20-11 product page. The BoltMAR 20-11 would appear to be based on the general design of Eurotech’s older ReliaGate IoT gateways, which similarly run Wind River Linux on Intel Atom processors. The fanless system is furnished with a 24VDC nominal (9-36VDC) @ 0. 8A power supply, and runs at a nominal 19W, says Eurotech. Other service panel accessible ports include VGA, RS-232, and 2x USB 2. 0 host ports. The system provides 2x Fast Ethernet ports available via the service panel, as well as a ruggedized 5-port Ethernet switch. ” Applications include control systems, information display systems, remote sensor management, vehicle-to-vehicle and on-board communications, high-speed networking, and surveillance, in industrial, fleet management, defense, and public safety... The built-in Cisco 5921 ESR software includes Internet routing protocols, VLAN support, and mobility features such as Mobile IP and Radio Aware routing. The system also provides dual-band (2. 4/5. 0GHz) high transmit power WiFi designed for vehicle area networks, with the 802. 11a/b/g/n WiFi radio providing up to 25dBm TX output power. The feature set is much like that of the similarly named ReliaGATE 20-11 and the BoltMAR 20-11 shares the same old-school, 1. 1GHz Intel Z510P processor used by the ReliaGate 50-21 , which was announced back in 2014. The BoltMAR 20-11 ships with... In addition to providing a flexible mobile cellular access router with up to 32 VLANs per router, the device features a variety of optional, IP67-rated USB-based ReliaCELL Modular Cellular Adapters with different 2G, 3G, and 4G radios. A rear-panel M2 connector combines a third USB port, a second RS-232 port, a RS-232/RS-422/RS-485 port, and 2x CAN ports. BoltMAR 20-11. The BoltMAR 20-11 features Cisco IOS-powered routing, internetworking, and management, and is designed for applications “where an existing Cisco based infrastructure is in place. Designed to showcase the Linux-driven Cisco 5921 Embedded Services Router (ESR) software, this entry-level, EN50155-compliant Mobile Access Router (MAR) “allows field-proven Cisco internetworking to be extended to enterprise fleet applications in...

Key areas of interest include innovation, digital transformation, cloud computing, mobility, information security, ecommerce and big data. D-Link apparently downplayed the findings and suggested Kim found the issues by chance, reported ZDNet. Security researcher Pierre Kim revealed his findings in a blog post. The scale of the problem, including 10 zero-day vulnerabilities, is alarming, as noted by the International Business Times. The publication reported that the U. S. Federal Trade Commission sued D-Link recently, suggesting the manufacturer relied on inadequate security measures that left users vulnerable to hacking. Both versions of the router, revA and revB, are affected by the flaws. The vulnerabilities are such that Kim said he could compromise everything, including the wireless area network, the local area network and the custom Mydlink cloud protocol, in his test. Threat actors could potentially use the flaws to gain root access and control routers remotely. Late last year, fraudsters claimed to have compromised 3. 2 million home routers by pushing a new firmware update that caused the devices to reach out to malicious servers even after being reset. He explained, “The D-Link 850L is a router overall badly designed with a lot of vulnerabilities. What Is the Extent of the Router Security Issue. It is also worth noting that router security has long been viewed as a potential weak point. Other manufacturers have also been affected by router security issues. ” He advised members of the public to “immediately disconnect vulnerable routers from the internet. Users and IT managers alike must stay alert to this risk and follow Kim’s suggestion to disconnect affected routers from the internet. News of the flaw adds to a growing body of evidence surrounding the potential threat posed by router security concerns. News of the router security issues should raise alarm among members of the public. Kim said in his blog post that the vulnerabilities were discovered in the D-Link 850L, which is a wireless AC1200 dual-band gigabit cloud router. Security researcher and chairman of the GDI Foundation, Victor Gevers, estimated there are about 95,000 D-Link 850L routers that are potentially exposed, reported Bleeping Computer. The 10 zero-day vulnerabilities cover a range of router security concerns, including firmware protection, administration passwords and backdoor access. Router security fears have prompted a researcher to recommend that members of the general public disconnect their D-Link 850L routers from the internet. Cisco announced a critical router vulnerability last year and Ubiquiti Networks issued a security alert in May 2016 as a response to reports that its routers had seen infections performed by a worm.
