O-RAN Near Realtime RIC ric-plt-submgr | J-Release
How the Exploit Works
The exploit works by sending a specially crafted request to the Subscription Manager API component of the O-RAN Near Realtime RIC ric-plt-submgr. The malformed request triggers an error in the system, causing an unexpected condition that leads to a denial of service. Furthermore, in some circumstances, this could lead to a system compromise or data leakage.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This example represents a malicious HTTP request to the vulnerable API endpoint.
POST /api/subscription HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "crafted_request_that_causes_dos" }
Mitigation Measures
Until a patch is provided by the vendor to rectify this vulnerability, it is recommended to use Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) as a temporary mitigation. These measures can help detect and block malicious requests, thereby limiting the potential impact of this vulnerability.
