A critical vulnerability has been discovered in zhijiantianya ruoyi-vue-pro 2.4.1, which is classified as CVE-2025-2040. This vulnerability is located in an unknown functionality of the file /admin-api/bpm/model/deploy, and its manipulation could cause improper neutralization of special elements used in a template engine. The vulnerability can be exploited remotely, and the exploit is now publicly available. This article is an exclusive discussion of the vulnerability and provides links to original references and a code snippet that demonstrates the issue.

Exploit Details

The vulnerability discovered, CVE-2025-2040, affects the zhijiantianya ruoyi-vue-pro 2.4.1 and is classified as critical. An attacker exploiting this vulnerability can remotely manipulate the deployment model in the /admin-api/bpm/model/deploy file leading to improper handling of special elements in a template engine. This can result in unauthorized access, data leakage, or even complete system compromise.

During an analysis of the code base, it was found that the problematic function is located within the /admin-api/bpm/model/deploy file, which handles deployment of the application's business process model. Due to improper sanitization of user inputs, an attacker can supply specially crafted input strings that have the potential to break out of the expected context and execute arbitrary code.

Code Snippet

The following code snippet is a demonstration of the vulnerability in action. It uses a sample manipulation that, if executed, could cause the improper neutralization of special elements and lead to the vulnerability being exploited.

// Vulnerable code in /admin-api/bpm/model/deploy

function deployModel(payload) {
  // ... other code ...
  let template = compileTemplate(payload)
  let rendered = template(payload)

  // ... other code ...
}

// User input that can exploit the vulnerability
const payload = {
  name: '{{ payload.name }}',
  description: 'This description has a vulnerability: {{ payload.description }}',
  // ... other malicious payloads ...
}

// Exploitation through a crafted payload
deployModel(payload)
