    VAR-201302-0026

    Vulnerability from variot - Updated: 2025-04-11 22:59

    Moxa EDR-G903 series routers with firmware before 2.11 do not use a sufficient source of entropy for (1) SSH and (2) SSL keys, which makes it easier for man-in-the-middle attackers to spoof a device or modify a client-server data stream by leveraging knowledge of a key from a product installation elsewhere. The MOXA EDR-G903 is a series of all-in-one firewall/VPN secure router devices with Gigabit performance. MOXA EDR-G903 is prone to an unauthorized access vulnerability and a weakness in the entropy of the generated key. Successful exploits will allow attackers to gain access to the device and sensitive information. Successful exploits may result in the attacker executing arbitrary commands or gain unauthorized access on the affected system. Moxa EDR-G903 is a security router product from Moxa that integrates firewall/VPN. The vulnerability is caused by the program not using enough resource entropy for (1) SSH and (2) SSL keys. A man-in-the-middle attacker could exploit this vulnerability to counterfeit a device or modify client-server traffic by exploiting keys that the product secures elsewhere. ----------------------------------------------------------------------

    The final version of the CSI 6.0 has been released. Find out why this is not just another Patch Management solution: http://secunia.com/blog/325/

        "data": "Moxa EDR-G903 series routers with firmware before 2.11 do not use a sufficient source of entropy for (1) SSH and (2) SSL keys, which makes it easier for man-in-the-middle attackers to spoof a device or modify a client-server data stream by leveraging knowledge of a key from a product installation elsewhere. The MOXA EDR-G903 is a series of all-in-one firewall/VPN secure router devices with Gigabit performance. MOXA EDR-G903 is prone to an unauthorized access vulnerability and a weakness in the entropy of the generated key. \nSuccessful exploits will allow attackers to gain access to the device and sensitive information. Successful exploits may result in the attacker executing arbitrary commands or gain unauthorized access on the affected system. Moxa EDR-G903 is a security router product from Moxa that integrates firewall/VPN. The vulnerability is caused by the program not using enough resource entropy for (1) SSH and (2) SSL keys. A man-in-the-middle attacker could exploit this vulnerability to counterfeit a device or modify client-server traffic by exploiting keys that the product secures elsewhere. ----------------------------------------------------------------------\n\nThe final version of the CSI 6.0 has been released. \nFind out why this is not just another Patch Management solution: http://secunia.com/blog/325/\n\n----------------------------------------------------------------------\n\nTITLE:\nMoxa EDR-G903 Series Weak Entropy Key Generation Weakness\n\nSECUNIA ADVISORY ID:\nSA52141\n\nVERIFY ADVISORY:\nSecunia.com\nhttp://secunia.com/advisories/52141/\nCustomer Area (Credentials Required)\nhttps://ca.secunia.com/?page=viewadvisory\u0026vuln_id=52141\n\nRELEASE DATE:\n2013-02-12\n\nDISCUSS ADVISORY:\nhttp://secunia.com/advisories/52141/#comments\n\nAVAILABLE ON SITE AND IN CUSTOMER AREA:\n * Last Update\n * Popularity\n * Comments\n * Criticality Level\n * Impact\n * Where\n * Solution Status\n * Operating System / Software\n * CVE Reference(s)\n\nhttp://secunia.com/advisories/52141/\n\nONLY AVAILABLE IN CUSTOMER AREA:\n * Authentication Level\n * Report Reliability\n * Secunia PoC\n * Secunia Analysis\n * Systems Affected\n * Approve Distribution\n * Remediation Status\n * Secunia CVSS Score\n * CVSS\n\nhttps://ca.secunia.com/?page=viewadvisory\u0026vuln_id=52141\n\nONLY AVAILABLE WITH SECUNIA CSI AND SECUNIA PSI:\n * AUTOMATED SCANNING\n\nhttp://secunia.com/vulnerability_scanning/personal/\nhttp://secunia.com/vulnerability_scanning/corporate/wsus_sccm_3rd_third_party_patching/\n\nDESCRIPTION:\nA weakness has been reported in Moxa EDR-G903 Series, which can be\nexploited by malicious people to conduct brute force attacks. \n\nThe weakness is reported in firmware versions prior to 2.11. \n\nSOLUTION:\nUpdate to version 2.11. \n\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nPROVIDED AND/OR DISCOVERED BY:\nICS-CERT credits Neil Smith\n\nORIGINAL ADVISORY:\nMOXA:\nhttp://www.moxa.com/support/download.aspx?type=support\u0026id=492\n\nICS-CERT:\nhttp://ics-cert.us-cert.gov/pdf/ICSA-13-042-01.pdf\n\nOTHER REFERENCES:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nDEEP LINKS:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nEXTENDED DESCRIPTION:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nEXTENDED SOLUTION:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nEXPLOIT:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\n----------------------------------------------------------------------\n\nAbout:\nThis Advisory was delivered by Secunia as a free service to help\nprivate users keeping their systems up to date against the latest\nvulnerabilities. \n\nSubscribe:\nhttp://secunia.com/advisories/secunia_security_advisories/\n\nDefinitions: (Criticality, Where etc.)\nhttp://secunia.com/advisories/about_secunia_advisories/\n\n\nPlease Note:\nSecunia recommends that you verify all advisories you receive by\nclicking the link. \nSecunia NEVER sends attached files with advisories. \nSecunia does not advise people to install third party patches, only\nuse those supplied by the vendor. \n\n----------------------------------------------------------------------\n\nUnsubscribe: Secunia Security Advisories\nhttp://secunia.com/sec_adv_unsubscribe/?email=packet%40packetstormsecurity.org\n\n----------------------------------------------------------------------\n\n\n",

    VAR-201302-0035

    Vulnerability from variot - Updated: 2025-04-11 22:59

    Moxa EDR-G903 series routers with firmware before 2.11 have a hardcoded account, which allows remote attackers to obtain unspecified device access via unknown vectors. The MOXA EDR-G903 is a series of all-in-one firewall/VPN secure router devices with Gigabit performance. The MOXA EDR-G903 series router has a built-in user account and password. MOXA EDR-G903 is prone to an unauthorized access vulnerability and a weakness in the entropy of the generated key. Successful exploits will allow attackers to gain access to the device and sensitive information. Successful exploits may result in the attacker executing arbitrary commands or gain unauthorized access on the affected system. Moxa EDR-G903 is a security router product from Moxa that integrates firewall/VPN. ----------------------------------------------------------------------

    The final version of the CSI 6.0 has been released. Find out why this is not just another Patch Management solution: http://secunia.com/blog/325/

    DESCRIPTION: A weakness has been reported in Moxa EDR-G903 Series, which can be exploited by malicious people to conduct brute force attacks.

    The weakness is caused due to weak entropy used when generating HTTPS and SSH keys, which can be exploited to brute force the private key based on the host key and disclose sensitive information via Man-in-the-Middle (MitM) attacks.

    The weakness is reported in firmware versions prior to 2.11.

    SOLUTION: Update to version 2.11.

        "data": "Moxa EDR-G903 series routers with firmware before 2.11 have a hardcoded account, which allows remote attackers to obtain unspecified device access via unknown vectors. The MOXA EDR-G903 is a series of all-in-one firewall/VPN secure router devices with Gigabit performance. The MOXA EDR-G903 series router has a built-in user account and password. MOXA EDR-G903 is prone to an unauthorized access vulnerability and a weakness in the entropy of the generated key. \nSuccessful exploits will allow attackers to gain access to the device and sensitive information. Successful exploits may result in the attacker executing arbitrary commands or gain unauthorized access on the affected system.

    CVE-2012-4694 (GCVE-0-2012-4694)

    Vulnerability from nvd – Published: 2013-02-15 11:00 – Updated: 2024-09-16 17:03
    VLAI
    Summary
    Moxa EDR-G903 series routers with firmware before 2.11 do not use a sufficient source of entropy for (1) SSH and (2) SSL keys, which makes it easier for man-in-the-middle attackers to spoof a device or modify a client-server data stream by leveraging knowledge of a key from a product installation elsewhere.
    Severity
    No CVSS data available.
