Detailsinfo

A vulnerability, which was classified as very critical, was found in Advantech EKI-6333AC-2G, EKI-6333AC-2GD and EKI-6333AC-1GPO (affected version not known). This affects the function cfg_cmd_set_eth_conf of the component edgserver Service. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A CWE-78 "Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')" was discovered affecting the following devices manufactured by Advantech: EKI-6333AC-2G (<= 1.6.3), EKI-6333AC-2GD (<= v1.6.3) and EKI-6333AC-1GPO (<= v1.2.1). The vulnerability can be exploited by remote unauthenticated users capable of interacting with the default "edgserver" service enabled on the access point and malicious commands are executed with root privileges. No authentication is enabled on the service and the source of the vulnerability resides in processing code associated to the "cfg_cmd_set_eth_conf" operation.
