CVE-2025-47245: Privilege Escalation Vulnerability in BlueWave Checkmate

Overview

The cybersecurity landscape is peppered with threats that seek to compromise systems and leak sensitive data. One such vulnerability that has recently come to light is CVE-2025-47245. This vulnerability affects BlueWave Checkmate versions up to 2.0.2, prior to the d4a6072 update. This vulnerability is significant because it allows an attacker to modify an invite request to specify a privileged role. If successfully exploited, this could lead to a system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-47245

Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

BlueWave Checkmate | Up to 2.0.2 before d4a6072

How the Exploit Works

The vulnerability lies in the invite request feature of BlueWave Checkmate. An attacker can manipulate this feature to assign themselves a privileged role. Once this is accomplished, they can exploit their elevated access to compromise the system or leak sensitive data. The manipulation is possible due to insufficient input validation and lack of authorization checks when processing invite requests.

Conceptual Example Code

Here is a conceptual HTTP request that demonstrates how the vulnerability might be exploited:

POST /invite/request HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"invitee": "attacker@example.com",
"role": "admin"
}

In this example, an attacker sends an invite request for themselves but specifies an ‘admin’ role. If the application lacks appropriate checks, this request could be processed successfully, granting the attacker admin privileges.

Mitigation and Prevention

To mitigate this vulnerability, users are advised to apply the vendor patch. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) might offer temporary mitigation. These systems can be configured to block or alert on suspicious invite request modifications. However, these are not long-term solutions, and system administrators should apply the vendor patch as soon as possible to fully resolve the vulnerability.
