ChanCMS is a content management system used by various organizations for managing web content effectively. It's often utilized to create and manage both personal and professional websites due to its robust features. With a simple installation process and user-friendly interface, it's popular among small businesses and individual website creators. ChanCMS offers plugin support, which enhances its core functionalities, making it adaptable for specific needs. Regular updates provide users with improved features and security enhancements. However, like many CMS platforms, ChanCMS needs vigilant updates and monitoring to maintain optimal security levels.
The detected vulnerability in ChanCMS is a Remote Code Execution (RCE), which poses significant security risks. This vulnerability allows attackers to execute arbitrary code on the server, potentially compromising the entire system. The issue arises due to insecure deserialization, particularly in the handling of the "targetUrl" argument within specific modules. RCE vulnerabilities are critical as they can lead to unauthorized access and control over server operations. Without remediation, affected systems are at severe risk of disruption or data breach. It's crucial for users to update their systems to the latest secure version.
Technical details reveal that the vulnerability is found in the app/modules/cms/controller/collect.js file. The "getArticle" function within this script accepts user input via the "targetUrl" parameter. This input isn't properly sanitized, allowing crafted input to manipulate the system. Attackers can inject payloads through HTTP requests, leading to the execution of arbitrary commands. During the attack, specific user privileges or crafted data can grant an attacker control over the host system. This vulnerability highlights the importance of thorough input validation and secure coding practices to prevent exploitation.
Exploitation of this vulnerability can lead to severe outcomes for affected systems. It enables attackers to execute malicious scripts, potentially leading to data loss, data theft, and unauthorized administrative access. Additionally, successful exploitation might allow for the installation of malware or the creation of backdoors, further compromising system integrity. Full system compromise could result in service disruptions, financial losses, and damage to organizational reputation. Therefore, mitigating this vulnerability is essential to protect sensitive information and maintain service availability.
