CVE-2020-20601 Scanner

ThinkCMF is a content management framework widely used by developers to create web applications and portals. It is leveraged due to its modularity, ease of use, and extensive plugin ecosystem, which allows developers to customize and expand the functionality according to their needs. The framework is commonly used by smaller to medium-sized enterprises and developers who require efficient solutions for their web development projects. Due to its open-source nature, ThinkCMF can be freely modified, which is particularly attractive to developers who want to adapt the framework to specific requirements. The product has a community of contributors who continuously enhance its capabilities and security features. However, like with any framework, maintaining updates and monitoring for vulnerabilities remains crucial.

This scanner identifies Remote Code Execution vulnerabilities in ThinkCMF X2.2.2 and below versions. A Remote Code Execution (RCE) vulnerability allows attackers to execute arbitrary code on a target system remotely. The presence of this vulnerability can give attackers unrestricted access to the affected systems, allowing them to execute commands and potentially disrupt services or steal sensitive data. RCE vulnerabilities are considered severe due to their potential impact and the level of control they can give to an attacker over an infected system. Keeping up with updates and patches is crucial to mitigate such vulnerabilities. Because of this, internet-facing instances of ThinkCMF might be at significant risk if not properly safeguarded.

Technical details of the vulnerability include the processing of crafted packets, which are then able to execute arbitrary code on the system. The execution path includes calls to the endpoint located at '/index.php?g=g&m=Door&a=index&content=

The possible effects of this vulnerability can be detrimental to the affected organization or individual. Once exploited, attackers can gain complete control over the application, leading to unauthorized data access or manipulation. This can result in data breaches where sensitive customer or enterprise data is accessed, altered, or deleted, negatively impacting the organization's reputation and causing financial loss. Furthermore, the exploitation can be a channel for further payloads or malware, perpetuating a cycle of vulnerabilities. Ensuring systems are up-to-date, and proper application security practices are in place is essential to avoid these scenarios.
