CVE-2026-48909 Scanner

The Joomla SP LMS is a comprehensive learning management system (LMS) for Joomla, used by educators and organizations to facilitate online learning, course management, and training programs. Developed by JoomShaper, this software aims to provide an efficient, user-friendly platform for creating and managing educational content and resources. It is commonly utilized by schools, universities, training centers, and businesses offering e-learning solutions to streamline their educational processes. Its features include course creation, student management, quizzes, and progress tracking, making it a versatile tool for various educational needs. The Joomla SP LMS is known for its integration capabilities with Joomla, allowing users to enhance their learning environments with a wide array of Joomla extensions and templates. It is a popular choice for institutions seeking a reliable and customizable LMS on the Joomla platform.

The vulnerability in the Joomla SP LMS, specifically in versions up to 4.1.3, allows for Remote Code Execution (RCE) by unauthenticated attackers. This serious security flaw occurs due to the deserialization of user-controlled cookie data without proper validation. As a result, remote attackers can exploit this vulnerability to execute arbitrary code on the server, which can compromise the entire system. The vulnerability is classified as critical, given its severity and the potential for complete data breach or system takeover if successfully exploited. Its exploitation does not require authentication, increasing its risk profile significantly. Addressing this vulnerability involves upgrading to a secured version that addresses this critical flaw.

The vulnerability details indicate that the deserialization flaw is present in the way user-controlled cookie data is processed by versions of Joomla SP LMS up to 4.1.3. The attack involves sending specially crafted cookie data to the server, which is then deserialized without appropriate checks, allowing for arbitrary code execution. The vulnerable endpoint can be reached by accessing specific functions in the LMS, such as the cart view in com_splms. Successful exploitation allows attackers to write and execute PHP code on the server, potentially leading to the disclosure of sensitive data and manipulation of the learning management content, compromising the integrity of the educational platform.

Exploiting this vulnerability could have dire consequences on the affected systems, including unauthorized access to sensitive educational data, alteration or deletion of course content, and total disruption of the learning management process. Malicious actors could gain complete control over the platform, leading to data breaches and potential spread of malware. The consequences extend to financial and reputational damage for the institutions using the LMS, with significant implications for data protection compliance and trust with users. A successful attack could disrupt continuous educational services and potentially endanger the privacy of all users involved with the platform.
