TITLE

Moxa IKS and EDS Buffer error vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-002198

DESCRIPTION

Several buffer overflow vulnerabilities have been identified in Moxa IKS and EDS, which may allow remote code execution. Moxa IKS and EDS Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. MoxaIKS and EDS are Moxa's line of industrial switches. A buffer overflow vulnerability exists in the MoxaIKS and EDS families. An attacker could exploit this vulnerability for remote code execution. 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
