Aikcms is a content management system used by individuals and organizations for creating and managing digital content. It offers tools for managing text, images, and files, making it useful for web developers, content creators, and businesses. Its reliance on customizable templates and plugins allows users to expand its functionality. Many small to medium-sized businesses employ aikcms to create interactive websites and manage web-based content without needing extensive programming knowledge. Moreover, its interface caters to both novice and professional users, ensuring a manageable learning curve with robust features. The system's flexibility and adaptability make it a preferred choice for those seeking dynamic content management solutions.

The vulnerability found in aikcms version v2.0.0 allows for unrestricted file uploads, which represent a significant security risk. This type of vulnerability can occur when the application does not validate or sanitize uploaded files correctly. An attacker could upload a file with executable code and execute it, potentially leading to unauthorized access or system compromise. Failure to enforce file type restrictions can enable the delivery and execution of malicious payloads. This oversight poses threats not just to the host web server but can potentially serve as a launchpad for broader attacks. Ultimately, such vulnerabilities could permit full server control or unauthorized data exposure.

Unrestricted File Upload vulnerabilities in aikcms pertain to the lack of proper validation for uploaded content. The vulnerable endpoint is identified as "admin/page/system/admin.php," which allows attackers to upload files directly. This endpoint fails to restrict filenames or content types, letting attackers use extensions like php to execute server-side commands. The form parameter "aik_admin_img" is particularly vulnerable as it allows file uploads with malicious intents. Attackers can manipulate the server to interpret and run executable files, despite mime type checks. Such vulnerabilities underscore the importance of implementing stringent file validation mechanisms.

If exploited, the Unrestricted File Upload vulnerability can have severe consequences. Attackers may gain the ability to execute arbitrary scripts, leading to potential data breaches. There is a significant risk of unauthorized access, allowing attackers to modify, delete, or exfiltrate sensitive data. Executing malicious code could result in further exploitation, such as pivoting into internal networks or establishing persistent backdoors. Additionally, attackers could deface web pages, engage in phishing attacks, or use server resources for malicious activities like botnet coordination. The overall security integrity of the affected systems would be critically undermined.
