Roothub 2.5 Arbitrary File Upload Vulnerability.

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2024-33120

The vulnerability involves an arbitrary file upload function in a web application. Web applications are commonly deployed as internet-facing services, and file upload endpoints are frequently exposed to facilitate user interaction or content management, making public network reachability a common deployment pattern for this type of product.

Attack Path

How an attacker could exploit the issue

An attacker can reach the vulnerable Roothub application over the internet and upload a malicious file through a specific function. This allows them to execute arbitrary code on the server, potentially leading to a complete compromise of the system.

No special access needed.
Upload a crafted JSP file.
Arbitrary code execution.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an unauthenticated attacker to upload and execute arbitrary code on the affected system through a specially crafted JSP file. This could lead to the compromise of the server's integrity and availability when the application is accessible over a network.

Arbitrary code execution.
Via network-accessible file upload.
Server compromise and availability loss.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Roothub platform owner is responsible for addressing this critical vulnerability. The first step is to identify all instances of Roothub, determine their business criticality and network exposure, and then coordinate remediation with the vendor or internal teams.

Platform owners are responsible.

Frequently asked questions

What is Roothub?

Roothub is a software platform used for managing various data or services. Version 2.5 is specifically impacted by a flaw in how it processes uploaded files, which is a core feature often used for updating content or system configurations within the application.

What does CWE-434 mean for CVE-2024-33120?

CWE-434 identifies a weakness where an application allows users to upload files without sufficient restrictions on the type or content of the file. In the case of CVE-2024-33120, this means the software fails to properly filter inputs, enabling an attacker to upload and subsequently execute a malicious file.

How can an attacker trigger this vulnerability?

An attacker triggers this by interacting with the upload function in the application and supplying a specifically crafted JSP file through the customPath parameter. Simply visiting the login page or browsing static content does not activate the bug; it requires active exploitation of the file upload mechanism.

Is my Roothub instance at risk?

Halo Surface Signal notes that since this is a web-based file upload issue, it is highly likely to be internet-facing. If your Roothub instance is reachable over the public internet, it carries a higher risk than a system restricted to an isolated internal network.

How do I respond to this threat?

Start by identifying every instance of Roothub 2.5 within your environment. Once identified, evaluate the network accessibility of these servers and prioritize them based on their importance to your operations, then engage with your internal teams or the vendor to secure or update the affected systems.
