Summary
by MITRE • 10/21/2026
A vulnerability was found in MomoTommy file-management-system dc9ce1bf27f94b23d906cb1e86ce374dc94ca5df. This issue affects the function index/store/update/destroy of the file app/Http/Controllers/FileController.php of the component Files API. The manipulation of the argument Request results in missing authentication. The attack can be launched remotely. The exploit has been made public and could be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The project was informed of the problem early through an issue report but has not responded yet.

Analysis

The identified vulnerability in the MomoTommy file-management system represents a critical authentication bypass within its core Files API functionality. Specifically, the flaw resides in the FileController.php component, affecting key endpoints responsible for indexing, storing, updating, and destroying files. The root cause is traced to improper handling of HTTP request arguments, which leads to missing or ineffective authentication checks before these sensitive operations are executed. This architectural weakness allows any remote actor to interact with file management functions without providing valid credentials, effectively rendering the access control mechanisms obsolete for this specific module.
From a technical perspective, this issue aligns closely with CWE-287, Improper Authentication, and potentially CWE-306, Missing Authentication for Critical Function. The absence of mandatory authentication checks on state-changing operations such as file deletion or modification creates a severe integrity risk. An attacker can exploit this by crafting specific HTTP requests to the affected endpoints, bypassing any intended security layers that should validate user identity and permissions prior to processing the request. This type of flaw is often indicative of insufficient input validation logic within the controller layer, where the framework's middleware for authentication may have been incorrectly configured or explicitly skipped for these routes.
The operational impact of this vulnerability is substantial due to its remote exploitability and public availability. Since the attack can be launched remotely over a network connection, an adversary does not need local access or prior compromise of user sessions to initiate exploitation. The fact that the exploit has already been made public significantly increases the likelihood of automated scanning tools targeting vulnerable instances in real-time. Successful exploitation could lead to unauthorized file uploads, leading to potential web shell deployment and subsequent server takeover, as well as arbitrary file deletion which results in complete data loss for affected users. Furthermore, the ability to update files allows attackers to deface content or inject malicious scripts into legitimate documents stored within the system.
Complicating remediation efforts is the lack of versioning information for this product. Without a structured release history, it is impossible to determine if newer commits have addressed the issue through code changes that are not reflected in traditional semantic version numbers. The specific commit hash provided serves as the only reference point for the vulnerable state, and since the project has not responded to early reports of the problem, there is no official patch or mitigation guidance available from the maintainers. This leaves system administrators with limited options beyond manual code review and modification.
To mitigate this risk in the absence of an official update, immediate action must focus on enforcing strict authentication at the application level. Developers should audit the FileController.php to ensure that all public methods are protected by middleware or decorators that verify valid user sessions before execution. Implementing role-based access control (RBAC) is also recommended to restrict file operations based on user privileges rather than allowing unrestricted access. Additionally, deploying a Web Application Firewall with rules tuned for authentication bypass patterns can provide an external layer of defense against automated exploitation attempts while the underlying code issue remains unresolved. Regular security audits and static analysis tools should be integrated into the development lifecycle to prevent similar misconfigurations in future releases.
