Raisecom Multi-Service Intelligent Gateway Remote Code Execution Scanner

Raisecom Multi-Service Intelligent Gateway is commonly deployed in network environments to facilitate intelligent routing and network management across various services. It is utilized by organizations that require robust networking solutions to manage complex telecommunications setups and ensure efficient data transmission. Network administrators and IT professionals often use this gateway to streamline connectivity and enhance operational efficiency in both small and large-scale deployments. The gateway plays a crucial role in modern networking by providing reliable communication paths and managing traffic between different network nodes. It supports a wide range of networking protocols and is designed for scalability, allowing it to adapt to varying organizational needs. As such, it's a critical component in maintaining the infrastructure of businesses relying on seamless network operations.

The Remote Code Execution (RCE) vulnerability identified in the Raisecom Multi-Service Intelligent Gateway is critical as it allows attackers to execute arbitrary commands on the affected device. This vulnerability exists due to improper input sanitization on the stylenum parameter of the /vpn/vpn_template_style.php endpoint. An attacker can exploit this vulnerability by injecting system commands using specific characters, such as backticks or pipes, which are interpreted as command inputs by the system. This type of vulnerability is particularly dangerous as it enables remote users to execute potentially malicious code without prior authentication. Exploitation of RCE vulnerabilities can lead to full system compromise, allowing attackers to perform unauthorized actions like data manipulation or service disruption. Detection and remediation of such vulnerabilities are crucial to maintaining the security of the affected systems.

The technical specifics of the RCE vulnerability in the Raisecom Multi-Service Intelligent Gateway reveal that the problem lies in the system's failure to sanitize incoming data appropriately. The vulnerable endpoint, /vpn/vpn_template_style.php, does not properly filter the user input passed to the stylenum parameter. This oversight allows attackers to manipulate the input and introduce command syntax that the system executes, leading to arbitrary code execution. The exploitation steps involve crafting a payload that incorporates command sequences wrapped in backticks or using pipes within the parameter value. By doing so, attackers can inject and execute commands on the server, utilizing it to gain unauthorized access, escalate privileges, or disrupt normal operations. The compromised endpoint presents a significant security risk, necessitating immediate patching and application of proper input validation techniques.

Successful exploitation of the assessed vulnerability provides malicious actors with the ability to execute commands remotely, potentially leading to complete system compromise. Once exploited, attackers can manipulate files, modify system configurations, or gain control over the device. The potential impacts include unauthorized data access, system downtime, and facilitation of additional attack vectors within the affected network. Not only does this compromise the security posture of the organization, but it can also lead to data exfiltration or introduce liabilities associated with breach of data protection regulations. The severity of the potential impacts underscores the importance of timely mitigation processes and the implementation of robust detection mechanisms.
