It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-4489 in the wild and no public exploit code.\n\nAffected product: silabs.com Z/IP Gateway SDK. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-4489/ (Markdown: https://insights.sbomify.com/CVE-2023-4489/index.md)","id":"CVE-2023-4489","markdown":"https://insights.sbomify.com/CVE-2023-4489/index.md","name":"CVE-2023-4489","record":{"aliases":["GHSA-6jw3-xmj9-qvcw"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Z/IP Gateway SDK","requires_auth":"none","summary":"Predictable S0 encryption keys due to uninitialized PRNG allow unauthorized network access in Z/IP Gateway products.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Silabs","cpe":[{"product":"z\\/ip_gateway_sdk","vendor":"silabs"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"},{"id":"CWE-1279","name":"Cryptographic Operations are Run Before Supporting Units are Ready"}],"description":"The first S0 encryption key is generated with an uninitialized PRNG in Z/IP Gateway products running Silicon Labs Z/IP Gateway SDK v7.18.3 and earlier.
