LotusCMS Remote Code Execution Scanner

LotusCMS is an open-source content management system used by individuals and organizations to manage digital content efficiently. It's widely adopted due to its customizable features and ease of use, allowing both novice and experienced users to establish and manage dynamic websites. However, the lack of regular updates and potential security vulnerabilities may expose LotusCMS installations to various risks. It's primarily deployed in environments where cost-effective and straightforward web content management is paramount. System administrators and webmasters use LotusCMS to facilitate the organization and presentation of content with minimal coding knowledge. As with any content management system, ensuring security through regular updates and patches is critical to maintaining a secure website environment.

Remote Code Execution (RCE) is a critical vulnerability allowing attackers to execute arbitrary code on a server or system, often with escalated privileges. This vulnerability can be exploited remotely without the need for authentication, making it highly severe. Such vulnerabilities allow malicious actors to control affected systems, potentially leading to data theft, system compromise, and further attacks on connected systems. In LotusCMS, the RCE vulnerability is associated with the improper handling of the 'page' parameter, enabling the injection of harmful scripts. Systems left unprotected against this vulnerability are at significant risk of being exploited. Addressing such vulnerabilities promptly through patches and updates is essential to maintain system security

The technical exposure in LotusCMS allowing Remote Code Execution is due to the vulnerable 'Router()' function, which improperly processes inputs. By injecting PHP code into the 'page' parameter, attackers can exploit the flaw through an unsanitized eval call. This call executes the injected code on the server, granting attackers unauthorized control over the system. The exploitation does not necessitate prior authentication, increasing the risk of widespread attacks. Critical server scripts can be manipulated or read, leading to potential data exfiltration and server manipulation. The vulnerable endpoints in question are accessed typically via POST requests submitted to index.php or lcms/index.php.

Exploitation of this vulnerability might result in unauthorized full control over affected systems, with attackers potentially installing malware, stealing confidential data, or interrupting services. There may be a risk of infecting other systems within the network, leading to further compromise. Successful exploitation of an RCE vulnerability can lead to the availability, integrity, and confidentiality of data being negatively impacted. Systems left unaddressed may also be turned into botnets for further attacks. It is crucial to implement robust security measures and update systems promptly to mitigate such risks.
