Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-20160 and fix it if it is affected.\n\nWhat it is: CVE-2021-20160 is a high-severity command injection vulnerability in Trendnet AC2600 TEW-827DRU, published on 30 Dec 2021. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20160 in the wild and no public exploit code.\n\nAffected product: Trendnet AC2600 TEW-827DRU. 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-2021-20160/ (Markdown: https://insights.sbomify.com/CVE-2021-20160/index.md)","id":"CVE-2021-20160","markdown":"https://insights.sbomify.com/CVE-2021-20160/index.md","name":"CVE-2021-20160","record":{"aliases":["GHSA-wjhv-44c8-252g"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Trendnet wireless router","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary commands as root via the SMB username parameter in Trendnet AC2600 routers.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"tew-827dru_firmware","vendor":"trendnet"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Trendnet AC2600 TEW-827DRU version 2.08B01 contains a command injection vulnerability in the smb functionality of the device.
