Ruijie EG Easy Gateway Remote Code Execution Scanner

The Ruijie EG Easy Gateway is widely used by businesses and network administrators to manage and monitor internet connectivity and network performance. It's a versatile platform that provides features such as bandwidth management, content filtering, and network security. Most commonly found in small to medium enterprises, the Ruijie EG Easy Gateway enhances the operational stability of network environments. Network managers appreciate its user-friendly interface and the ability to streamline various network management tasks. It is crucial in environments where secure and stable internet access is necessary. Additionally, it plays a significant role in providing robust security against unauthorized access.

Remote Code Execution (RCE) is a critical vulnerability that allows an attacker to execute arbitrary code on a target machine. This vulnerability exploits a flaw in the software that fails to sufficiently validate user inputs or the environment before executing commands or scripts. RCE vulnerabilities are highly dangerous as they often grant attackers complete control over the affected systems. The severity of RCE vulnerabilities can range from data theft and unauthorized transactions to causing a complete system compromise. Detecting RCE vulnerabilities typically requires specialized scanning tools that can simulate malicious input scenarios. Mitigation of RCE vulnerabilities often entails thorough input validation and system hardening practices.

The vulnerability in the Ruijie EG Easy Gateway arises from the login.php endpoint, where improper input handling allows malicious commands to run on the server. Attackers can send specially crafted HTTP requests containing these commands to the login form of the gateway. The product fails to sanitize input parameters like 'username' and 'password', allowing remote attackers to gain admin-level access. Successful exploitation of this vulnerability can lead to complete system takeover. Furthermore, the use of weak default credentials exacerbates the risk. Proper authentication and input validation are critical defense measures to combat such vulnerabilities.

If exploited, the Remote Code Execution vulnerability could allow attackers to execute arbitrary commands, potentially compromising sensitive data or taking over the system. Attackers could steal administrative credentials, install malware, or disrupt services, leading to data breaches and operational downtime. The impact of exploiting RCE vulnerabilities is particularly severe as it affects confidentiality, integrity, and availability. Businesses relying on the Ruijie EG Easy Gateway could face significant reputational and financial damage if the vulnerability is exploited. Immediate remediation and continuous monitoring are necessary to protect against potential exploitation.
