A specially crafted HTTP POST request can cause a privilege escalation resulting in access to root shell. An attacker may be able to inject OS commands into the CN= parm in the \"/goform/net_WebCSRGen\" uri to trigger this vulnerability. \n \n\n\n### TALOS-2017-0478 (CVE-2017-12126) Moxa EDR-810 Web Server Cross-Site Request Forgery Vulnerability\n\n \n[TALOS-2017-0478](<http://www.talosintelligence.com/reports/TALOS-2017-0478>) is an exploitable cross-site request forgery (CSRF) vulnerability that exists in the web server functionality of Moxa EDR-810. A specially crafted HTTP request can trigger a CSFR vulnerability which may allow the attacker to change the device configuration. An attacker can create a malicious html code to trigger this vulnerability and entice the user to execute the malicious code. \n \n\n\n### TALOS-2017-0479 (CVE-2017-12127) Moxa EDR-810 Plaintext Password Storage Vulnerability\n\n \n[TALOS-2017-0479](<http://www.talosintelligence.com/reports/TALOS-2017-0479>) is a password storage vulnerability that exists in the operating system functionality of Moxa EDR-810. The device stores credentials in plaintext in /magicP/cfg4.0/cfg_file/USER_ACCOUNT.CFG. This file mirrors the contents of /etc/shadow, except that all the passwords are stored in plaintext. \n \n\n\n### TALOS-2017-0480 (CVE-2017-12128) Moxa EDR-810 Server Agent Information Disclosure Vulnerability\n\n \n[TALOS-2017-0480](<http://www.talosintelligence.com/reports/TALOS-2017-0480>) is an exploitable information disclosure vulnerability that exists in the Server Agent functionality of Moxa EDR-810. A specially crafted TCP packet can cause the device to leak data and result in an information disclosure. An attacker may be able to send a specially crafted TCP packet to trigger this vulnerability. \n \n\n\n### TALOS-2017-0481 (CVE-2017-12129) Moxa EDR-810 Web Server Weak Cryptography for Passwords Vulnerability\n\n \n[TALOS-2017-0481](<http://www.talosintelligence.com/reports/TALOS-2017-0481>) is an exploitable Weak Cryptography for Passwords vulnerability that exists in the web server functionality of Moxa EDR-810. After the initial login, each authenticated request sends a HTTP packet with a MD5 hash of the password. This hash is not salted and can be cracked, revealing the device's password. \n \n\n\n### TALOS-2017-0482 (CVE-2017-14432 to 14434) Moxa EDR-810 Web Server OpenVPN Config Multiple Command Injection Vulnerabilities\n\n \n[TALOS-2017-0482](<http://www.talosintelligence.com/reports/TALOS-2017-0482>) describes multiple exploitable command injection vulnerabilities that exist in the web server functionality of Moxa EDR-810. A specially crafted HTTP POST request may cause a privilege escalation resulting in an attacker having access to a root shell. An attacker may be able to inject OS commands into various parameters in the \"/goform/net_Web_get_value\" uri to trigger this vulnerability. \n \n\n\n### TALOS-2017-0487 (CVE-2017-14438 and 14439) Moxa EDR-810 Service Agent Multiple Denial of Service\n\n \n[TALOS-2017-0487](<http://www.talosintelligence.com/reports/TALOS-2017-0487>) describes two exploitable denial of service vulnerabilities that exist in the Service Agent functionality of Moxa EDR-810.

ICS systems employ many mechanisms and protocols also used in traditional IT systems and networks. \n \nAlthough some characteristics of traditional IT systems and ICS are similar, ICS also have characteristics that differ in their service level and performance requirements. Many of these differences come from the fact that ICS has a direct effect on the physical world which may also include a risk to the health and safety of the population and a potential to cause damage to the environment. For that reason ICS have unique reliability requirements and may use real-time operating systems and applications that would not be used in everyday IT environments. \n \nOne of the pillars of ICS security, as well as the security of traditional IT networks, is restricting access to network activity. This may include unidirectional gateways, a demilitarized zone (DMZ) network architecture with firewalls and separate authentication mechanisms and credentials for users of corporate and ICS networks. \n \nICS devices, including firewalls that secure networks, run software which can contain vulnerabilities and serve as a pathway that may allow attackers to take advantage and intrude into an ICS network environment. \n \nCisco Talos vulnerability research team also focuses on non traditional computing environments, including ICS, to find previously unknown vulnerabilities and work with vendors to responsibly disclose them while allowing the vendor enough time to improve security of the products by fixing the discovered vulnerabilities. \n \nMoxa EDR-810 is one of the devices specialized in providing firewalls specifically designed to function within ICS infrastructure and provide network security to ICS processes. Cisco Talos researchers have discovered several vulnerabilities affecting the security of the product. Moxa EDR-810 users are recommended to update the software as soon as possible to avoid their ICS environment potentially being exploited by attackers. \n \n\n\n## Coverage\n\n \nThe following Snort Rules detect attempts to exploit these vulnerabilities.
