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-2021-27426 in the wild and no public exploit code.\n\nAffected product: GE UR family. 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-2021-27426/ (Markdown: https://insights.sbomify.com/CVE-2021-27426/index.md)","id":"CVE-2021-27426","markdown":"https://insights.sbomify.com/CVE-2021-27426/index.md","name":"CVE-2021-27426","record":{"aliases":["GHSA-qwcv-4jvg-f4mr"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"GE UR IED firmware","requires_auth":"none","summary":"GE UR IED firmware fails to disable Factory Mode in Basic security variant, allowing unauthorized access to servicing functions.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"multilin_b30_firmware","vendor":"ge"},{"product":"multilin_b90_firmware","vendor":"ge"},{"product":"multilin_c30_firmware","vendor":"ge"},{"product":"multilin_c60_firmware","vendor":"ge"},{"product":"multilin_c70_firmware","vendor":"ge"},{"product":"multilin_c95_firmware","vendor":"ge"},{"product":"multilin_d30_firmware","vendor":"ge"},{"product":"multilin_d60_firmware","vendor":"ge"},{"product":"multilin_f35_firmware","vendor":"ge"},{"product":"multilin_f60_firmware","vendor":"ge"},{"product":"multilin_g30_firmware","vendor":"ge"},{"product":"multilin_g60_firmware","vendor":"ge"},{"product":"multilin_l30_firmware","vendor":"ge"},{"product":"multilin_l60_firmware","vendor":"ge"},{"product":"multilin_l90_firmware","vendor":"ge"},{"product":"multilin_m60_firmware","vendor":"ge"},{"product":"multilin_n60_firmware","vendor":"ge"},{"product":"multilin_t35_firmware","vendor":"ge"},{"product":"multilin_t60_firmware","vendor":"ge"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-453","name":"Insecure Default Variable Initialization"}],"description":"GE UR IED firmware versions prior to version 8.1x with “Basic” security variant does not allow the disabling of the “Factory Mode,” which is used for servicing the IED by a “Factory” user.","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":"GE UR family insecure default variable initialization","id":"CVE-2021-27426","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"RIOT OS Integer Overflow or Wraparound","id":"CVE-2021-27427"},"packages":[],"prev":{"headline":"Cesanta Software Mongoose-OS Integer Overflow or Wraparound","id":"CVE-2021-27425"},"products":["UR family"],"published":"2022-03-23","related":[{"cvss_score":9.8,"headline":"GE UR family Unrestricted Upload of File with Dangerous Type","id":"CVE-2021-27428","kev_date_added":null,"published":"2022-03-23"},{"cvss_score":7.5,"headline":"GE UR family exposure of sensitive information to an unauthorized actor","id":"CVE-2021-27422","kev_date_added":null,"published":"2022-03-23"},{"cvss_score":5.3,"headline":"GE UR family input validation","id":"CVE-2021-27418","kev_date_added":null,"published":"2022-03-23"},{"cvss_score":5.3,"headline":"GE UR family input validation","id":"CVE-2021-27420","kev_date_added":null,"published":"2022-03-23"},{"cvss_score":5.3,"headline":"GE UR family exposure of sensitive information to an unauthorized actor","id":"CVE-2021-27424","kev_date_added":null,"published":"2022-03-23"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-16","vendors":["GE"]},"summary":"GE UR IED firmware fails to disable Factory Mode in Basic security variant, allowing unauthorized access to servicing functions.","url":"https://insights.sbomify.com/CVE-2021-27426/"}
