Detailsinfo

A vulnerability has been found in FlexRIC 2.0.0 and classified as problematic. Affected by this vulnerability is the function assert of the component RIC Service. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. The summary by CVE is:

FlexRIC v2.0.0 contains a reachable assertion in the iApp message dispatcher. The dispatcher validates incoming E2AP messages against a 9-entry whitelist using assert(). A remote unauthenticated attacker can send any decodable E2AP PDU with a message type not in the whitelist to crash the iApp process (port 36422) via SIGABRT. Since iApp and the near-RT RIC share one process, this terminates the entire RIC service and disconnects all E2 Nodes and xApps.
