How the Exploit Works
An attacker with low privileged access can exploit this vulnerability by sending specially crafted HTTP requests to the affected Oracle Hospitality Simphony product. The vulnerability allows for the compromise of the Oracle application due to a flaw in the EMC component. Once successful, the attacker could gain unauthorized access to critical data, modify or delete some of the accessible data, and even cause a partial denial of service.
Conceptual Example Code
POST /EMC/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "exploit_data": "<malicious_code>" }In the above conceptual example, the attacker sends a POST request containing the malicious code in the “exploit_data” parameter to the vulnerable EMC endpoint.
Mitigation Guidance
Users are advised to apply the vendor patch as soon as it becomes available. In the meantime, mitigation can be achieved by deploying a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block suspicious network traffic. Regular security audits and monitoring are also recommended to detect any unusual activity.
