Product web page: http://www.microhardcorp.com Affected version: IPn4G 1.1.0 build 1098 IPn3Gb 2.2.0 build 2160 IPn4Gb 1.1.6 build 1184-14 IPn4Gb 1.1.0 Rev 2 build 1090-2 IPn4Gb 1.1.0 Rev 2 build 1086 Bullet-3G 1.2.0 Rev A build 1032 VIP4Gb 1.1.6 build 1204 VIP4G 1.1.6 Rev 3.0 build 1184-14 VIP4G-WiFi-N 1.1.6 Rev 2.0.0 build 1196 IPn3Gii / Bullet-3G 1.2.0 build 1076 IPn4Gii / Bullet-LTE 1.2.0 build 1078 BulletPlus 1.3.0 build 1036 Dragon-LTE 1.1.0 build 1036 Summary: The new IPn4Gb provides a rugged, industrial strength wireless solution using the new and ultra fast 4G LTE cellular network infrastructure. The IPn4Gb features integrated Firewall, IPSec / VPN & GRE Tunneling, IP/MAC Access Control Lists. The IPn4Gb can transport critical data to and from SMS, Ethernet and Serial RS232/485/422 devices! The IPn3Gb provides a fast, secure industrial strength wireless solution that uses the widespread deployment of cellular network infrastructure for critical data collection. From remote meters and sensors, to providing mobile network access, the IPn3Gb delivers! The IPn3Gb is a powerful HSPA+ and Quad Band GSM device compatible almost anywhere. It provides robust and secure wireless communication of Serial, USB and Ethernet data. The all new Bullet-3G provides a compact, robust, feature packed industrial strength wireless solution using fast 3G/HSPA+ network infrastructure. The Bullet-3G takes things to the next level by providing features such as Ethernet with PoE, RS232 Serial port and 2x Programmable I/O. Offering enhanced, 'Secure Communication' with its integrated Firewall, IPSec VPN Tunneling, IP/MAC Access Control Lists, the Bullet-3G is a solution worth looking at! The all new Dragon-LTE provides a feature packed, compact OEM, industrial strength wireless IoT & M2M solution. Connect any device, wired or wireless, and provide remote cellular access using the Dragon-LTE. The Dragon-LTE features a OEM design for tight system integration and design flexibility with dual Ethernet Ports and high power 802.11b/g/n WIFI. With its integrated Firewall, IPSec VPN Tunneling and IP/MAC Access Control Lists, the Dragon-LTE provides a solution for any cellular application! The new VIP4Gb provides a rugged, industrial strength wireless solution using 4G LTE network infrastructure for critical data communications. The VIP4Gb provides simultaneous network connections for 802.11a/b/g/n WiFi devices, 4 x 10/100/1000 Ethernet ports, Digital I/O, and a RS232/RS485 port, resulting in a communication device that can be deployed in any application! The VIP4Gb is a powerful 4G LTE device compatible on any cellular network. It provides robust and secure wireless communication of Serial, Ethernet & WiFi data. Desc: The application suffers from multiple authenticated arbitrary remote code execution vulnerabilities with highest privileges. This is due to multiple hidden and undocumented features within the admin interface that allows an attacker to create crontab jobs and/or modify the system startup script that allows execution of arbitrary code as root user.
