CVE-2024-53790 is a path traversal vulnerability identified in Ogun Labs Lenxel Core for Lenxel(LNX) LMS, a learning management system product used for educational content delivery and management. The vulnerability arises from improper limitation of pathname inputs, allowing attackers to manipulate file paths to access files outside the intended restricted directories. This flaw enables PHP Local File Inclusion (LFI), where an attacker can include and execute arbitrary files on the server, potentially leading to sensitive information disclosure, configuration file exposure, or remote code execution if combined with other vulnerabilities. The affected versions include all releases up to and including version 1.3.9. The vulnerability does not require prior authentication, increasing the risk of exploitation by remote attackers. Although no public exploits have been reported yet, the nature of LFI vulnerabilities makes them attractive targets for attackers seeking to escalate privileges or pivot within compromised environments. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. Given the potential for confidentiality breaches and system compromise, this vulnerability represents a significant threat to organizations relying on Lenxel LMS for their educational infrastructure.

The exploitation of CVE-2024-53790 can have severe consequences for organizations using Lenxel LMS. Attackers could gain unauthorized access to sensitive files such as configuration files, user data, or credentials stored on the server, compromising confidentiality. In some cases, local file inclusion can be leveraged to execute arbitrary code, threatening system integrity and availability. This can lead to data breaches, disruption of educational services, and loss of trust among users and stakeholders. Since the vulnerability does not require authentication, it can be exploited remotely, increasing the attack surface. Organizations in education sectors, especially those with limited cybersecurity resources, may face significant operational and reputational damage. Additionally, attackers might use this vulnerability as a foothold to launch further attacks within the network, escalating the overall risk.

To mitigate CVE-2024-53790, organizations should prioritize the following actions: 1) Monitor Ogun Labs announcements for official patches and apply them promptly once released. 2) Implement strict input validation and sanitization on all user-supplied pathname parameters to prevent directory traversal sequences such as '../'. 3) Employ web application firewalls (WAFs) configured to detect and block path traversal and LFI attack patterns. 4) Restrict file system permissions for the web server process to limit access to only necessary directories and files, minimizing the impact of potential exploitation. 5) Conduct regular security audits and code reviews focusing on file inclusion and path handling logic within the LMS. 6) Use security headers and disable unnecessary PHP functions that could facilitate code execution. 7) Educate administrators and developers about secure coding practices related to file handling. These measures collectively reduce the risk of exploitation even before patches are available.
