An attacker needs administrator access to exploit it, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-20164 and fix it if it is affected.\n\nWhat it is: CVE-2021-20164 is a medium-severity vulnerability in Trendnet AC2600 TEW-827DRU, published on 30 Dec 2021. An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20164 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-2021-20164/ (Markdown: https://insights.sbomify.com/CVE-2021-20164/index.md)","id":"CVE-2021-20164","markdown":"https://insights.sbomify.com/CVE-2021-20164/index.md","name":"CVE-2021-20164","record":{"aliases":["GHSA-wrgm-3c24-9q9r"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Trendnet wireless router","requires_auth":"high_privilege","summary":"An attacker can view plaintext SMB credentials for all users on the Trendnet AC2600 router via the smbserver.asp page.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"tew-827dru_firmware","vendor":"trendnet"}],"cvss":{"score":4.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"Trendnet AC2600 TEW-827DRU version 2.08B01 improperly discloses credentials for the smb functionality of the device.
