An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-20150 and fix it if it is affected.\n\nWhat it is: CVE-2021-20150 is a medium-severity authentication bypass vulnerability in Trendnet AC2600 TEW-827DRU, published on 30 Dec 2021. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-20150 exists.\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-2021-20150/ (Markdown: https://insights.sbomify.com/CVE-2021-20150/index.md)","id":"CVE-2021-20150","markdown":"https://insights.sbomify.com/CVE-2021-20150/index.md","name":"CVE-2021-20150","record":{"aliases":["GHSA-6wmh-r824-376w"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Trendnet wireless router","requires_auth":"none","summary":"Attackers can bypass authentication and view admin information by forcing a redirect from the setup wizard on Trendnet routers.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"tew-827dru_firmware","vendor":"trendnet"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Trendnet AC2600 TEW-827DRU version 2.08B01 improperly discloses information via redirection from the setup wizard.
