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-2020-3375 in the wild and no public exploit code.\n\nAffected product: Cisco SD-WAN vManage. 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-2020-3375/ (Markdown: https://insights.sbomify.com/CVE-2020-3375/index.md)","id":"CVE-2020-3375","markdown":"https://insights.sbomify.com/CVE-2020-3375/index.md","name":"CVE-2020-3375","record":{"aliases":["GHSA-76f8-hj3g-qcfw"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco SD-WAN vManage","requires_auth":"none","summary":"Unauthenticated remote attackers can exploit a buffer overflow in Cisco SD-WAN vManage to execute commands as root, read data, and modify the system.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios_xe_sd-wan","vendor":"cisco"},{"product":"sd-wan","vendor":"cisco"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability in Cisco SD-WAN Solution Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected device.
