An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-20697 and fix it if it is affected.\n\nWhat it is: CVE-2021-20697 is a critical missing authorization vulnerability in D-Link Japan K.K. DAP-1880AC, published on 26 Apr 2021. 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-2021-20697 in the wild and no public exploit code.\n\nAffected product: D-Link Japan K.K. DAP-1880AC. 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-2021-20697/ (Markdown: https://insights.sbomify.com/CVE-2021-20697/index.md)","id":"CVE-2021-20697","markdown":"https://insights.sbomify.com/CVE-2021-20697/index.md","name":"CVE-2021-20697","record":{"aliases":["GHSA-m8wx-mf3r-7hff"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link access point","requires_auth":"none","summary":"Remote attackers can bypass authentication to access critical functions on D-Link DAP-1880AC devices, gaining unauthorized user privileges.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"dap-1880ac_firmware","vendor":"dlink"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Missing authentication for critical function in DAP-1880AC firmware version 1.21 and earlier allows a remote attacker to login to the device as an authenticated user without the access privilege via unspecified vectors.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing authorization in DAP-1880AC","id":"CVE-2021-20697","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in C431","id":"CVE-2021-20698"},"packages":[],"prev":{"headline":"Command injection in DAP-1880AC","id":"CVE-2021-20696"},"products":["DAP-1880AC"],"published":"2021-04-26","related":[{"cvss_score":8.8,"headline":"Auth bypass in DAP-1880AC","id":"CVE-2021-20694","kev_date_added":null,"published":"2021-04-26"},{"cvss_score":8.8,"headline":"Security feature bypass in DAP-1880AC","id":"CVE-2021-20695","kev_date_added":null,"published":"2021-04-26"},{"cvss_score":8.8,"headline":"Command injection in DAP-1880AC","id":"CVE-2021-20696","kev_date_added":null,"published":"2021-04-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["D-Link Japan K.K."]},"summary":"Remote attackers can bypass authentication to access critical functions on D-Link DAP-1880AC devices, gaining unauthorized user privileges.","url":"https://insights.sbomify.com/CVE-2021-20697/"}
