How the Exploit Works
The exploitation of this vulnerability involves an attacker creating a maliciously crafted webpage that, when visited and interacted with by an authenticated user, will force the user’s browser to perform unauthorized actions on the vulnerable application. In this case, the attacker can inject malicious objects into the INVELITY MyGLS Connect application through a CSRF attack, potentially leading to a system compromise or data leakage.
Conceptual Example Code
Here is a conceptual example of how this vulnerability might be exploited:
POST /invelity_mygls_connect/endpoint HTTP/1.1
Host: vulnerable.example.com
Content-Type: application/json
Cookie: session=valid_user_session
{ "malicious_object": "..." }In this example, the attacker uses a valid user session (acquired through some other means, such as phishing or session hijacking) to send a POST request with a malicious object payload to the vulnerable endpoint of the INVELITY MyGLS Connect application.
Mitigation and Prevention
To mitigate this vulnerability, users and administrators of the affected INVELITY MyGLS Connect versions are advised to apply the vendor patch as soon as it’s available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary mitigation by blocking or detecting malicious requests. Regular security audits and updates, as well as educating users about the dangers of phishing attacks and the importance of secure browsing, can further help prevent successful exploitation of this vulnerability.
