aikcms_v2 Arbitrary File Upload Scanner

The aikcms_v2 software is widely used for content management purposes in various web applications. It allows users and administrators to efficiently manage web content through a user-friendly interface. The software is often utilized by web developers, small to medium-sized businesses, and individuals looking to build functional websites with minimal effort. Users can benefit from the potential for quick content updates, rich media handling, and a variety of extension capabilities. Developers appreciate its integration capabilities, making it easier to enhance functionality without extensive customization. However, as with any web software, maintaining security updates is crucial to ensure ongoing safety and performance.

The Arbitrary File Upload vulnerability allows attackers to upload unauthorized files to a server running the aikcms_v2 software. This can occur due to improper validation and restrictions on file types that can be uploaded. Such vulnerabilities pose significant risks since attackers may leverage them to upload scripts or executables, potentially leading to unauthorized actions or data breaches. The core concern with this vulnerability lies in file handling processes, where the system's inability to differentiate between safe and malicious file types allows exploitation. Failure to address this vulnerability can lead to severe security implications on systems running the vulnerable version.

Technical details of this vulnerability involve certain endpoints within aikcms_v2 that handle file uploads, such as "admin/page/user/usergroup_add.php". The vulnerability occurs due to insufficient checks on the file extension and type during the upload process. Attackers can craft requests with specific payloads, embedding executable or malicious code in uploaded files. Parameters like "aik_usergroup_img" may be exploited to upload files with dangerous extensions like ".php", which the server might execute. This lack of restrictions allows arbitrary file upload leading to potential malicious code execution on the server.

When exploited by malicious actors, the Arbitrary File Upload vulnerability can have severe consequences. Attackers may upload backdoors or web shells, allowing persistent access to the server and its resources. This unauthorized access might lead to data theft, server control, unauthorized configuration changes, or the use of the server for malicious activities such as launching further attacks. Overall, it poses a threat to confidentiality, integrity, and availability, with potential implications for the organization's reputation and legal standing if sensitive data is compromised.
