How the Exploit Works
The vulnerability arises from the widget’s improper handling of sensitive system information. Attackers can exploit this flaw to retrieve embedded sensitive data, potentially leading to unauthorized access to the system control sphere. This can result in the compromise of system integrity or data leakage.
Conceptual Example Code
An example of how this vulnerability might be exploited is shown in the following conceptual HTTP request:
GET /elfsight-contact-form/?sensitive_data=extract HTTP/1.1
Host: target.example.comIn this example, the malicious actor sends a GET request to the vulnerable endpoint. If the system is vulnerable, it will respond with the requested sensitive data.
Mitigation
To mitigate the risk posed by the CVE-2025-31045 vulnerability, users are advised to apply the latest vendor patch. If this is not feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary protection by monitoring network traffic and identifying potential security breaches.
