An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-3951 in the wild and no public exploit code.\n\nAffected product: Talos TP-Link. 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-2018-3951/ (Markdown: https://insights.sbomify.com/CVE-2018-3951/index.md)","id":"CVE-2018-3951","markdown":"https://insights.sbomify.com/CVE-2018-3951/index.md","name":"CVE-2018-3951","record":{"aliases":["GHSA-9r6w-5369-47xv"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TP-Link VPN router","requires_auth":"high_privilege","summary":"An attacker with authentication can trigger a buffer overflow in the HTTP server to execute arbitrary code on TP-Link TL-R600VPN devices.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"tl-r600vpn_firmware","vendor":"tp-link"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"An exploitable remote code execution vulnerability exists in the HTTP header-parsing function of the TP-Link TL-R600VPN HTTP Server.
