An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2017-20234 and fix it if it is affected.\n\nWhat it is: CVE-2017-20234 is a critical vulnerability in Belden GarrettCom Magnum 6K and 10K Managed Switches, published on 3 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-20234 in the wild and no public exploit code.\n\nAffected product: Belden GarrettCom Magnum 6K and 10K Managed Switches. 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-2017-20234/ (Markdown: https://insights.sbomify.com/CVE-2017-20234/index.md)","id":"CVE-2017-20234","markdown":"https://insights.sbomify.com/CVE-2017-20234/index.md","name":"CVE-2017-20234","record":{"aliases":["GHSA-vrjf-6q9f-r3qr"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Managed network switch","requires_auth":"none","summary":"Unauthenticated attackers can bypass login controls on GarrettCom Magnum switches using a hardcoded string to access administrative functions and sensitive configuration.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"GarrettCom Magnum 6K and 10K managed switches contain an authentication bypass vulnerability that allows unauthenticated attackers to gain unauthorized access by exploiting a hardcoded string in the authentication mechanism.
