TITLE

Moxa IKS and EDS Vulnerable to out-of-bounds reading

Trust: 0.8

sources: JVNDB: JVNDB-2019-002197

DESCRIPTION

Moxa IKS and EDS fails to properly check array bounds which may allow an attacker to read device memory on arbitrary addresses, and may allow an attacker to retrieve sensitive data or cause device reboot. Moxa IKS and EDS Contains an out-of-bounds read vulnerability.Information obtained and denial of service (DoS) May be in a state. MoxaIKS and EDS are Moxa's line of industrial switches. There is an out-of-bounds read vulnerability in the MoxaIKS and EDS series. The vulnerability stems from a program failing to properly validate array bounds. Moxa IKS and EDS are prone to following security vulnerabilities: 1. A cross-site-scripting vulnerability 2. Multiple stack-based buffer-overflow vulnerabilities 3. A security vulnerability 4. An information disclosure vulnerability 5. A cross-site request-forgery vulnerability 6. Multiple denial-of-service vulnerabilities 7. A security-bypass vulnerability 8. An authentication bypass vulnerability An attacker may leverage these issues to view arbitrary files within the context of the web server, execute arbitrary script code in the browser of the victim in the context of the affected site, steal cookie-based authentication credentials, gain access to sensitive information, compromise the application, access or modify data, reboot or crash of the application resulting in a denial of service condition, bypass security restrictions, or execute arbitrary code. This may lead to other vulnerabilities. The following Moxa products and versions are affected: IKS-G6824A series versions 4.5 and prior, EDS-405A series versions 3.8 and prior, EDS-408A series versions 3.8 and prior, and EDS-510A series versions 3.8 and prior. Moxa IKS-G6824A series are all products of Moxa Company in Taiwan, China. IKS-G6824A series is a series of rack-mount Ethernet switches. EDS-405A series is an EDS-405A series Ethernet switch. EDS-408A series is an EDS-408A series Ethernet switch
