The vulnerability CVE-2025-10353 represents a critical security flaw in Melis Technology's Melis Platform, specifically within the "melis-cms-slider" module. This issue manifests as a file upload vulnerability that can lead to remote code execution, making it particularly dangerous for web applications that rely on content management systems. The vulnerability exists in the Melis Platform's handling of file uploads through a specific endpoint that processes slider details, creating an attack vector that can be exploited by malicious actors to gain unauthorized access to affected systems. The flaw stems from inadequate input validation and sanitization mechanisms within the file upload functionality, allowing attackers to bypass security controls and execute arbitrary code on the target server.
The technical implementation of this vulnerability occurs when an attacker sends a POST request to the '/melis/MelisCmsSlider/MelisCmsSliderDetails/saveDetailsForm' endpoint with the 'mcsdetail_img' parameter containing a malicious file. This parameter is intended for image uploads but lacks proper validation to ensure that only legitimate image files are accepted. The vulnerability is categorized under CWE-434 which specifically addresses "Unrestricted Upload of File with Dangerous Type," indicating that the application accepts files without sufficient type checking or content verification. Attackers can leverage this flaw by uploading malicious files such as php shells or other executable code that gets stored on the server and subsequently executed when accessed by the web application. The attack chain typically involves uploading a crafted payload that, when processed by the slider module, results in code execution with the privileges of the web server process.
The operational impact of CVE-2025-10353 extends beyond simple unauthorized access, as it provides attackers with persistent control over affected systems. Once exploited, the vulnerability allows for complete compromise of the web application and potentially the underlying server infrastructure. Attackers can use the RCE capability to establish backdoors, exfiltrate sensitive data, escalate privileges, or launch further attacks against internal network resources. The vulnerability is particularly concerning because it affects a content management module that is likely frequently used and accessible to various user roles, increasing the attack surface and exploitation probability. Organizations using the Melis Platform may face data breaches, service disruption, and compliance violations if this vulnerability is exploited, especially in environments where sensitive customer or business data is managed through the CMS. The attack vector aligns with ATT&CK technique T1190 which covers "Exploit Public-Facing Application," highlighting how attackers can leverage web application vulnerabilities to gain initial access to target systems.
Mitigation strategies for CVE-2025-10353 should focus on implementing comprehensive file upload validation and sanitization mechanisms. Organizations must enforce strict file type validation by checking file extensions against a whitelist of allowed formats, implementing proper MIME type verification, and conducting content analysis to ensure uploaded files match their claimed types. The implementation of secure file upload practices includes storing uploaded files outside the web root directory, using random or unique filenames to prevent path traversal attacks, and implementing proper access controls for uploaded content. Additionally, organizations should restrict write permissions for upload directories and implement input validation at multiple layers including client-side and server-side validation. The Melis Platform vendors should provide immediate patches or updates to address the vulnerability, while security teams should conduct thorough penetration testing to identify similar issues in other modules. Network segmentation and monitoring solutions should be deployed to detect anomalous file upload activities and potential exploitation attempts, with security information and event management systems configured to alert on suspicious patterns related to the vulnerable endpoint. Regular security assessments and vulnerability scanning should be performed to identify and remediate similar issues across the entire application stack.
