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-2020-3426 in the wild and no public exploit code.\n\nAffected product: Cisco Ios. 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-2020-3426/ (Markdown: https://insights.sbomify.com/CVE-2020-3426/index.md)","id":"CVE-2020-3426","markdown":"https://insights.sbomify.com/CVE-2020-3426/index.md","name":"CVE-2020-3426","record":{"aliases":["GHSA-g97r-rvqc-x2fm"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Industrial Router","requires_auth":"none","summary":"Unauthenticated remote attackers can read sensitive data or cause denial of service on Cisco Industrial Routers via crafted VLPWA packets.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-264","name":null}],"description":"A vulnerability in the implementation of the Low Power, Wide Area (LPWA) subsystem of Cisco IOS Software for Cisco 800 Series Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) could allow an unauthenticated, remote attacker to gain unauthorized read access to sensitive data or cause a denial of service (DoS) condition.
