IMO Remote Code Execution Scanner

The IMO platform is widely utilized in corporate environments for cloud-based office solutions. It is especially popular among organizations seeking seamless integration of collaborative tools and document management. Designed for professional use, it serves as an essential tool for file sharing and business communications. Its functionality spans across document storage, sharing capabilities, and real-time collaboration among team members. With such comprehensive features, it is implemented by IT departments aiming to streamline office operations and enhance productivity. Due to its interconnected nature, any vulnerabilities within the platform could present significant risks to organizational security.

Remote Code Execution (RCE) vulnerabilities occur when an attacker can execute arbitrary code or commands on a target system through a specific flaw or weakness. This type of vulnerability can be highly dangerous because it allows attackers to potentially gain full control over the affected host. The threat vectors are extensive, as RCE can be exploited remotely over the network. Typically, this kind of vulnerability is caused by improper validation of user inputs, allowing malicious entities to inject and execute their own code. The ability to remotely execute code can compromise sensitive data and severely affect the integrity of the affected system. Therefore, detecting and mitigating RCE vulnerabilities is vital for maintaining security.

In the case of IMO, the lax filtering in the 'get_file.php' endpoint of the 'NDisk' feature is the entry point for this vulnerability. Attackers can manipulate the parameters, such as 'cid' and 'nid', to inject shell commands. Specifically, the vulnerability allows malicious actors to bypass security measures and execute commands within the host environment. The endpoint's inadequate validation fails to intercept harmful inputs, leading to potential unauthorized command execution. This opens the door for attackers to escalate privileges, extract sensitive information, and disrupt services hosted by the affected system. As a result, server integrity and data confidentiality are at significant risk.

If exploited, this RCE vulnerability could allow attackers direct access to sensitive server operations. Malicious individuals may escalate privileges, leading to unauthorized access to critical systems and data theft. The execution of arbitrary code has the potential to unleash a cascade of detrimental actions, including installing malware, altering configurations, and disrupting core services. Organizations could suffer from severe data breaches, financial losses, and damage to reputation. Prolonged exploitation of this vulnerability might also serve as a foothold for further attacks, potentially compromising the entire IT infrastructure.
