Affected Products

Product | Affected Versions

ColdFusion | 2025.2 and earlier
ColdFusion | 2023.14 and earlier
ColdFusion | 2021.20 and earlier

How the Exploit Works

The exploit takes advantage of an XXE vulnerability in ColdFusion. An attacker can craft a malicious XML document containing an external entity declaration that points to a URI of the attacker’s choice. By sending this document to the vulnerable system, the attacker can trigger the system to dereference the external entity, leading to information disclosure, denial of service, or potentially remote code execution.

Conceptual Example Code
```
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE foo [
<!ELEMENT foo ANY >
<!ENTITY xxe SYSTEM "file:///etc/passwd" >]>
<foo>&xxe;</foo>
```
In the above example, the attacker sends a POST request with a malicious XML payload that includes an external entity pointing to a sensitive file on the server. If the system is vulnerable, it will return the contents of this file in the response, revealing sensitive information to the attacker.

Mitigation Guidance

Affected systems should apply the patch provided by the vendor as soon as possible to mitigate the vulnerability. As a temporary measure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to filter out malicious XML content. However, this should not be considered a long-term solution, as it does not address the underlying vulnerability.

Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: System compromise and data leakage

Affected Products

Product | Affected Versions

mcp-remote | All versions prior to the patched

How the Exploit Works

The vulnerability arises from the crafted input from the authorization_endpoint response URL. If the mcp-remote software is connected to an untrusted MCP server, an attacker can inject commands into the authorization_endpoint response URL. Because the software does not properly sanitize the input from this URL, the injected commands are executed on the operating system running the mcp-remote software. This can lead to unauthorized access, system compromise, and potential data leakage.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited:
```
POST /authorization_endpoint HTTP/1.1
Host: untrusted.example.com
Content-Type: application/json
{ "malicious_payload": "injectable_os_command" }
```
In the above example, the “injectable_os_command” is a stand-in for any command that can be executed on the operating system running mcp-remote. Once this request is sent to the software, it executes the command, leading to the potential consequences described earlier.

Mitigation and Prevention

To mitigate this vulnerability, users of mcp-remote should immediately apply the vendor patch once available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary protection by identifying and blocking suspicious activities. Regularly updating and patching your software, using trusted servers, and routinely monitoring system activities are also recommended preventative measures to enhance cybersecurity resilience.

Conceptual Example Code

An attacker could potentially exploit this vulnerability by inspecting the client-side JavaScript bundles on a website employing the affected Docusaurus plugin. Conceptually, the process would look something like this:
```
// Fetch the source code of the website
fetch('https://vulnerable-website.com/main.js')
.then(response => response.text())
.then((data) => {
// Search for the GitHub Personal Access Token in the JavaScript bundle
let regex = /token\s*:\s*'([a-zA-Z0-9]*)'/;
let match = data.match(regex);
if (match) {
// If found, the token can be used maliciously
console.log('GitHub token found:', match[1]);
}
});
```
Mitigation and Vendor Patch

The vulnerability has been fixed in version 4.0.0 of the docusaurus-plugin-content-gists. Users are strongly advised to update their plugin to this version or later to mitigate the risk.
