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-2020-10887 in the wild and no public exploit code.\n\nAffected product: TP-Link Archer A7. 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-2020-10887/ (Markdown: https://insights.sbomify.com/CVE-2020-10887/index.md)","id":"CVE-2020-10887","markdown":"https://insights.sbomify.com/CVE-2020-10887/index.md","name":"CVE-2020-10887","record":{"aliases":["GHSA-4mxh-xfwq-hpgj"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"TP-Link Archer A7 router","requires_auth":"none","summary":"Attackers can bypass firewall restrictions on TP-Link Archer A7 routers by exploiting improper IPv6 SSH filtering, potentially leading to root code execution.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"ac1750_firmware","vendor":"tp-link"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-693","name":"Protection Mechanism Failure"}],"description":"This vulnerability allows a firewall bypass on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers.
