CAIMORE Gateway Remote Code Execution Scanner

The CAIMORE Gateway is a device manufactured by Xiamen Caimao Communication Technology Co., Ltd. that serves as an industrial wireless gateway using 3G/4G/5G networks for Internet communication. It is commonly used in industries requiring robust and reliable network communications. The device is equipped with a metal shell design and two Ethernet RJ45 interfaces, providing flexibility for various network configurations. Engineers and IT professionals utilize this gateway to facilitate seamless communication between devices over wide area networks. Its open software architecture makes it adaptable for numerous applications, from industrial automation to IoT solutions. The gateway is essential for organizations seeking to enhance connectivity while ensuring secure and rapid network communications.

The Remote Code Execution (RCE) vulnerability in the CAIMORE Gateway is a critical flaw that allows attackers to execute arbitrary code on the server hosting the gateway. This vulnerability is found in the 'formping' file, which lacks proper validation of user inputs. By exploiting this vulnerability, an attacker can gain unauthorized access to the server, allowing them to execute commands, install malicious programs, or access sensitive information. The severity of RCE vulnerabilities lies in their potential to compromise entire server infrastructures if left unaddressed. Addressing RCE vulnerabilities promptly is crucial in maintaining system integrity and preventing unauthorized system control.

The vulnerability is located within the 'formping' endpoint of the CAIMORE Gateway device. It originates from improper handling of user-supplied input, particularly when executing ping commands. The attacker can inject their own commands by manipulating parameters like 'PingAddr' using payloads. For instance, an injection of a string like '127.0.0.1%7Cecho%20{{randstr}}' is possible, enabling them to execute arbitrary commands on the server. These operations occur due to a lack of input sanitization, which fails to neutralize potentially harmful command sequences. This absence of input validation allows an attacker to take advantage of the execution environment within the gateway.

Exploitation of this vulnerability can lead to severe consequences, including unauthorized server access, data theft, and potential control over network resources. Attackers may deploy malware or establish backdoors to maintain persistent access. They can also disrupt operations by altering system configurations or deleting critical data. Additionally, unauthorized access to the server can facilitate wider network compromises, leading to further exploitation within connected systems. Organizations could face significant operational disruptions and reputation damage, necessitating prompt mitigation to protect their infrastructure.
