Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-1509 in the wild and no public exploit code.\n\nAffected product: Cisco SD-WAN vEdge router. 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-2021-1509/ (Markdown: https://insights.sbomify.com/CVE-2021-1509/index.md)","id":"CVE-2021-1509","markdown":"https://insights.sbomify.com/CVE-2021-1509/index.md","name":"CVE-2021-1509","record":{"aliases":["GHSA-x977-vgq2-xc7r"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SD-WAN router","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code as root or cause denial of service on Cisco SD-WAN vEdge routers via buffer overflow vulnerabilities.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"vedge_1000_firmware","vendor":"cisco"},{"product":"vedge_100_firmware","vendor":"cisco"},{"product":"vedge_100b_firmware","vendor":"cisco"},{"product":"vedge_100m_firmware","vendor":"cisco"},{"product":"vedge_100wm_firmware","vendor":"cisco"},{"product":"vedge_2000_firmware","vendor":"cisco"},{"product":"vedge_5000_firmware","vendor":"cisco"},{"product":"vedge_cloud_firmware","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Multiple vulnerabilities in Cisco SD-WAN vEdge Software could allow an attacker to execute arbitrary code as the root user or cause a denial of service (DoS) condition on an affected device.
