Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-42892 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-42892/ (Markdown: https://insights.sbomify.com/CVE-2021-42892/index.md)","id":"CVE-2021-42892","markdown":"https://insights.sbomify.com/CVE-2021-42892/index.md","name":"CVE-2021-42892","record":{"aliases":["GHSA-26pp-v5jf-7qcc"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TOTOLINK router","requires_auth":"low_privilege","summary":"Attackers can gain unauthorized telnet access to TOTOLINK EX1200T routers using hardcoded default credentials found in the firmware.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ex1200t_firmware","vendor":"totolink"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"In TOTOLINK EX1200T V4.1.2cu.5215, an attacker can start telnet without authorization because the default username and password exists in the firmware.","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":"Hardcoded credentials in n/a","id":"CVE-2021-42892","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in n/a","id":"CVE-2021-42893"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2021-42891"},"products":["n/a"],"published":"2022-06-03","related":[{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2025-51451","kev_date_added":null,"published":"2025-08-13"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2025-28038","kev_date_added":null,"published":"2025-04-22"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2025-28039","kev_date_added":null,"published":"2025-04-22"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2023-52032","kev_date_added":null,"published":"2024-01-11"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-42884","kev_date_added":null,"published":"2022-06-03"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-42885","kev_date_added":null,"published":"2022-06-03"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2021-42887","kev_date_added":null,"published":"2022-06-03"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can gain unauthorized telnet access to TOTOLINK EX1200T routers using hardcoded default credentials found in the firmware.","url":"https://insights.sbomify.com/CVE-2021-42892/"}
