PowerCreator CMS Remote Code Execution Scanner

PowerCreator CMS is an advanced content management system designed for managing digital content in an educational context. It is widely employed by educational institutions to create and manage web pages, courses, and digital resources efficiently. The software is typically used by administrators and educators who need to organize digital content and streamline workflow processes. Its user-friendly interface and robust features make it a preferred choice for schools and universities. PowerCreator CMS facilitates the easy dissemination of educational resources and fosters a collaborative online environment for learning. Overall, the software is instrumental in providing a structured approach to digital content management.

The vulnerability in PowerCreator CMS allows an attacker to execute arbitrary code on the server running the CMS. This Remote Code Execution (RCE) vulnerability is critical, as it could enable attackers to gain unauthorized access or control over the server. Exploiting this vulnerability doesn't require authentication, making it particularly dangerous. Attackers could potentially use this vulnerability to manipulate server operations or access sensitive data. As a consequence, it poses a significant risk to institutions relying on PowerCreator CMS for content management. Protecting against such a vulnerability is crucial to prevent potential data breaches and maintain system integrity.

Technical analysis reveals that the vulnerability exists in the file upload functionality of PowerCreator CMS. By constructing a special HTTP POST request, attackers can upload a malicious payload disguised as an image file. The endpoint vulnerable to this attack is located at "/upload/UploadResourcePic.ashx?ResourceID=8382". The uploaded file, which often uses an 'ASPX' extension, can then be accessed and executed remotely. Successful exploitation results in the execution of arbitrary code with high privileges on the server. This attack is considered critical due to its ease of execution and high impact on affected systems. Prompt action is required to mitigate this risk.

When exploited, this vulnerability can have devastating effects on the affected system. Attackers may gain full control over the server, manipulate its operations, and access or alter sensitive data. This could lead to severe consequences, including data leaks, service downtime, and overall system compromise. In educational settings, confidential information about students and staff could be exposed, affecting privacy and security. Additionally, the system's availability may be disrupted, leading to a loss of trust from users and stakeholders. It underscores the necessity for immediate remedial actions and preventive measures to protect against such exploits.
