Jeecg Boot Code Injection Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2024-40489

Jeecg Boot is a web application framework typically deployed as an internet-facing web application or API platform. Vulnerabilities in such frameworks that are reachable via crafted HTTP requests generally involve components that are commonly exposed to the public internet to provide web services or management interfaces.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory addresses a critical vulnerability in a web application framework that could allow unauthorized attackers to execute code remotely through simple web requests. The issue stems from inadequate filtering of characters within the framework, potentially impacting systems that rely on this technology. The main concern is confirming if our environment utilizes this specific framework and is therefore exposed.

Code execution via web requests.
Critical flaw in widely used framework.
Assess exposure to this web framework.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by sending specially crafted HTTP requests to an exposed web application. The application's inadequate filtering of characters within these requests allows the attacker to target specific components. Successful exploitation enables arbitrary code execution on the server, potentially leading to a complete system compromise.

Requires network access.
Triggered by malicious HTTP requests.
Leads to arbitrary code execution.

Live Threat

Current exploitation, exposure, and threat context

An injection vulnerability in jeecg-boot could allow attackers to execute arbitrary code on affected components by sending specially crafted HTTP requests. This is possible due to insufficient filtering of input characters.

Arbitrary code execution on the server.
Specially crafted HTTP requests.
Compromise of system integrity and confidentiality.

Operational Fix

Recommended remediation, mitigation, and detection steps

Teams responsible for Jeecg Boot applications, such as application owners and platform teams, should prioritize identifying all instances of the affected technology. Once located, confirm its reachability and business criticality to accurately assess risk and inform the remediation strategy. This includes engaging vendor-management if applicable and planning for necessary maintenance windows.

Own the vulnerability and its remediation.
Verify asset exposure and business impact.
Coordinate vendor engagement and patching.

Frequently asked questions

What is Jeecg Boot?

Jeecg Boot is an enterprise-level, low-code rapid development platform based on Java. It provides a full-stack framework used to build web applications and API services, automating common functions to accelerate software delivery.

What does CWE-94 mean for CVE-2024-40489?

This vulnerability is classified as CWE-94, or Improper Control of Generation of Code. It means the application fails to properly sanitize input, allowing an attacker to inject and execute their own code. Because Jeecg Boot does not adequately filter specific characters in requests, it unintentionally runs instructions provided by the attacker.

How does an attacker trigger this vulnerability?

An attacker triggers this flaw by sending a specially crafted HTTP request to the application. The system processes the malicious input without sufficient validation, leading to unauthorized code execution. It is important to note that normal, legitimate web traffic does not trigger this issue; the request must contain the specific, harmful characters that bypass the application's filtering.

Why does Halo Surface Signal categorize this as an external risk?

Halo Surface Signal flags this as an external risk because Jeecg Boot is typically deployed as an internet-facing web application or API platform. Since the vulnerability is reachable through standard network requests, any instance exposed to the public internet is at a higher risk of being targeted.

Do I need to take immediate action if I run Jeecg Boot?

Yes. If your environment uses Jeecg Boot versions 3.0.0 through 3.5.3, you should immediately identify all instances across your infrastructure. Once identified, evaluate their reachability and business criticality to determine the urgency of your response, then coordinate with your technical teams to plan maintenance or security updates.
