CVE-2024-51568 Scanner

CyberPanel is a popular web hosting control panel used by web admins and developers to manage websites and server resources. It provides an easy-to-use interface that simplifies various tasks, such as managing databases, domains, and email accounts. CyberPanel is known for its integration with OpenLiteSpeed, a fast web server solution, making it an attractive choice for hosting providers seeking performance and ease of use. The software is also renowned for offering features like automatic SSL management, Docker containers, and the ability to create multiple websites from a single dashboard. Due to its expansive capabilities, CyberPanel is often adopted by small to medium-sized businesses aiming to manage their digital presence efficiently. With a supportive community and extensive documentation, it remains a favored option for deploying web services.

The Command Injection vulnerability in CyberPanel allows attackers to execute arbitrary commands on the hosting server. This vulnerability emerges from inadequately sanitized inputs that can be exploited through the file manager upload functionality. When an attacker gains access, they are capable of initiating remote code execution with unauthorized server commands. Such vulnerabilities are critical due to their potential to compromise server integrity leading to data breaches or server outages. The lack of authentication in accessing the vulnerable endpoint amplifies the threat as it simplifies exploitation without prior user credentials. CyberPanel addressed this vulnerability in version 2.3.5, making earlier versions critical targets.

The Command Injection vulnerability resides in the completePath parameter of the /filemanager/upload endpoint, which fails to properly validate input data. Attackers can craft malicious inputs using shell metacharacters to manipulate command execution on the server. By exploiting this flaw, they can override normal operations, directing the server to execute arbitrary commands, potentially leading to unauthorized actions like downloading sensitive files or deploying malware. The technical flaw centers on the improper handling of HTTP POST requests without required input validation. Such lapses in security controls make the application susceptible to severe breaches and unauthorized data manipulation.

If exploited, this vulnerability can lead to several detrimental effects. Attackers may gain unauthorized access to server resources and execute harmful commands, compromising sensitive data integrity. Additionally, malicious actors could deploy malware, opening further vectors of attacks, or use the server as part of a botnet, contributing to broader attacks. This can result in significant downtime and loss of trust from users and clients, alongside potential financial and reputational damage. Moreover, such vulnerabilities often attract attention from a wide array of cyber criminals, exacerbating its potential impact.
