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-2020-27556 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-2020-27556/ (Markdown: https://insights.sbomify.com/CVE-2020-27556/index.md)","id":"CVE-2020-27556","markdown":"https://insights.sbomify.com/CVE-2020-27556/index.md","name":"CVE-2020-27556","record":{"aliases":["GHSA-3j6w-7mhc-r5hr"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"BASETech IoT device","requires_auth":"none","summary":"Unauthenticated remote attackers can connect to BASETech devices due to predictable device IDs, potentially leading to unauthorized access and data exposure.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ge-131_bt-1837836_firmware","vendor":"basetech"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"}],"description":"A predictable device ID in BASETech GE-131 BT-1837836 firmware 20180921 allows unauthenticated remote attackers to connect to the device.","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":"Auth bypass in n/a","id":"CVE-2020-27556","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2020-27557"},"packages":[],"prev":{"headline":"Hardcoded credentials in n/a","id":"CVE-2020-27555"},"products":["n/a"],"published":"2020-11-17","related":[{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2020-27555","kev_date_added":null,"published":"2020-11-17"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2020-27553","kev_date_added":null,"published":"2020-11-17"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2020-27554","kev_date_added":null,"published":"2020-11-17"},{"cvss_score":6.5,"headline":"Auth bypass in n/a","id":"CVE-2020-27558","kev_date_added":null,"published":"2020-11-17"},{"cvss_score":5.5,"headline":"Hardcoded credentials in n/a","id":"CVE-2020-27557","kev_date_added":null,"published":"2020-11-17"}],"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":"Unauthenticated remote attackers can connect to BASETech devices due to predictable device IDs, potentially leading to unauthorized access and data exposure.","url":"https://insights.sbomify.com/CVE-2020-27556/"}
