Description

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. In versions 7.0.0 to before 10.0.1, DNN.PLATFORM allows a specially crafted request or proxy to be created that could bypass the design of DNN Login IP Filters allowing login attempts from IP Addresses not in the allow list. This issue has been patched in version 10.0.1.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for DNN.PLATFORM, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update DNN.PLATFORM to 10.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fjhg-3mrh-mm7h is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-fjhg-3mrh-mm7h can be triaged on real exposure rather than presence alone.

Tailored to GHSA-fjhg-3mrh-mm7h. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Frequently Asked Questions

DNN.PLATFORM allows a specially crafted request or proxy to be created that would bypass the design of DNN Login IP Filters allowing login attempts from IP Adresses not in the allow list. This vulnerability is fixed in 10.0.1.
