Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An issue was discovered in FlexRIC 2.0.0. It crashes during a Subscription Request denial-of-service (DoS) attack, triggered by an assertion error. An attacker must send a high number of E42 Subscription Requests to the Near-RT RIC component.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

FlexRIC 2.0.0 contains a denial-of-service vulnerability in the Near-RT RIC component where processing a high volume of E42 Subscription Requests triggers an assertion error that crashes the service. The issue stems from improper handling of rapid subscription request traffic leading to assertion failures rather than graceful error handling.

MitigationReplace assertion-based error handling with proper error handling and input validation in the subscription request processing path. Implement rate limiting or throttling on E42 Subscription Requests to prevent mass request floods from causing crashes.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if FlexRIC is installed
    Look for flexric binaries, services, or processes on the system (e.g., run 'ps aux | grep flexric' or check common install directories)
    Affected if FlexRIC software is found on the system
  2. Confirm the installed FlexRIC version
    Run flexric --version or check version information in installed binaries/service metadata
    Affected if The version is 2.0.0 specifically (or falls within the affected range if later versions are published)
  3. Verify E42 Subscription Request processing is enabled
    Check configuration files or runtime settings for E42 subscription handler/subscription manager modules
    Affected if E42 subscription processing is configured or enabled in the Near-RT RIC configuration
  4. Review logs for assertion failures
    Examine FlexRIC service logs for assertion error messages related to E42 or subscription request handling
    Affected if Assertion failures in subscription processing code appear in logs after periods of high request traffic

If FlexRIC version 2.0.0 is running with E42 Subscription Request processing enabled and assertion errors appear in logs under load, the environment is affected by this CVE.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation

Replace assertion-based error handling with proper error handling and input validation in the subscription request processing path. Implement rate limiting or throttling on E42 Subscription Requests to prevent mass request floods from causing crashes.
