H3c IMC Remote Code Execution Scanner

H3c IMC is widely used by organizations for network management and monitoring. It provides a comprehensive platform that integrates network management functions across different layers and domains. Network administrators use it to ensure efficient operation, manage network resources, and secure the infrastructure. The software is essential for tracking bandwidth, monitoring device health, and generating performance reports. It offers scalability to manage both large and small networks and supports integration with a variety of network devices. H3c IMC serves as a central hub for network operations, significantly optimizing network performance and responsiveness.

The Remote Code Execution (RCE) vulnerability allows attackers to execute arbitrary code on the server hosting the H3c IMC software. This could be achieved by inputting malicious commands into vulnerable endpoints of the application. Such vulnerabilities are critical as they allow unauthorized users to gain a high degree of control over the affected system. RCE vulnerabilities typically require no user interaction, making them a significant threat. Attackers can leverage this flaw to manipulate the server environment, access sensitive information, or disrupt operations. It is imperative to identify and patch such vulnerabilities promptly to safeguard network infrastructure.

The technical details of the vulnerability involve the 'dynamiccontent.properties.xhtml' endpoint within the H3c IMC. This endpoint is susceptible to accepting unsanitized input, which can be exploited to run commands on the server. The vulnerability is triggered by sending a malicious POST request with the exploit payload as part of the form data. Parameters such as 'cmd' are particularly vulnerable if they are not properly sanitized or validated. This can lead to unauthorized access and control over the server resources, opening up several vectors for further exploits. Proper input validation and sanitization are critical in preventing such vulnerabilities.

If exploited, this vulnerability could lead to unauthorized access to the server, data breaches, and potential disruptions in service. Attackers could manipulate the network management settings, leading to misinformation or misconfiguration within the network environment. Sensitive data might be accessed or exfiltrated, posing confidentiality threats. The integrity of the system could be compromised, allowing the attacker to install backdoors or escalate privileges for continued access. Furthermore, business operations reliant on the network could face significant downtimes or inefficiencies, impacting overall business continuity.
