An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-28221 and fix it if it is affected.\n\nWhat it is: CVE-2020-28221 is a critical code injection vulnerability in EcoStruxure™ Operator Terminal Expert 3.1 Service Pack 1A and prior running on Harmony HMIs HMIST6 Series, HMIG3U in HMIGTU Series, HMISTO Series and Pro-face BLUE 3.1 Service Pack 1A and prior running on Pro-face HMIs: ST6000 Series, SP-5B41 in SP5000 Series, GP4100 Series, published on 25 Jan 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-2020-28221 in the wild and no public exploit code.\n\nAffected product: EcoStruxure™ Operator Terminal Expert 3.1 Service Pack 1A and prior running on Harmony HMIs HMIST6 Series, HMIG3U in HMIGTU Series, HMISTO Series and Pro-face BLUE 3.1 Service Pack 1A and prior running on Pro-face HMIs: ST6000 Series, SP-5B41 in SP5000 Series, GP4100 Series. 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-2020-28221/ (Markdown: https://insights.sbomify.com/CVE-2020-28221/index.md)","id":"CVE-2020-28221","markdown":"https://insights.sbomify.com/CVE-2020-28221/index.md","name":"CVE-2020-28221","record":{"aliases":["GHSA-rv39-23hm-r9j8"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"HMI software","requires_auth":"none","summary":"Improper input validation in EcoStruxure and Pro-face HMI software allows arbitrary code execution when the Ethernet Download feature is enabled.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"ecostruxure_operator_terminal_expert","vendor":"schneider-electric"},{"product":"pro-face_blue","vendor":"schneider-electric"}],"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-20","name":"Improper Input Validation"}],"description":"A CWE-20: Improper Input Validation vulnerability exists in EcoStruxure™ Operator Terminal Expert and Pro-face BLUE (version details in the notification) that could cause arbitrary code execution when the Ethernet Download feature is enable on the HMI.","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":"Code injection in EcoStruxure™ Operator Terminal Expert 3.1 Service Pack 1A and prior running on Harmony HMIs HMIST6 Series, HMIG3U in HMIGTU Series, HMISTO Series and Pro-face BLUE 3.1 Service Pack 1A and prior running on Pro-face HMIs: ST6000 Series, SP-5B41 in SP5000 Series, GP4100 Series","id":"CVE-2020-28221","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-28241"},"packages":[],"prev":{"headline":"Memory corruption in Modicon M258 Firmware (All versions prior to V5.0.4.11) and SoMachine/SoMachine Motion software (All versions)","id":"CVE-2020-28220"},"products":["EcoStruxure™ Operator Terminal Expert 3.1 Service Pack 1A and prior running on Harmony HMIs HMIST6 Series, HMIG3U in HMIGTU Series, HMISTO Series and Pro-face BLUE 3.1 Service Pack 1A and prior running on Pro-face HMIs: ST6000 Series, SP-5B41 in SP5000 Series, GP4100 Series"],"published":"2021-01-25","related":[{"cvss_score":9.8,"headline":"Path traversal in EcoStruxure Operator Terminal Expert 3.1 Service Pack 1 and prior (formerly known as Vijeo XD)","id":"CVE-2020-7497","kev_date_added":null,"published":"2020-06-16"},{"cvss_score":7.8,"headline":"Code injection in EcoStruxure™ Operator Terminal Expert","id":"CVE-2023-1049","kev_date_added":null,"published":"2023-06-14"},{"cvss_score":7.8,"headline":"SQL injection in EcoStruxure Operator Terminal Expert 3.1 Service Pack 1 and prior (formerly known as Vijeo XD)","id":"CVE-2020-7493","kev_date_added":null,"published":"2020-06-16"},{"cvss_score":7.8,"headline":"Path traversal in EcoStruxure Operator Terminal Expert 3.1 Service Pack 1 and prior (formerly known as Vijeo XD)","id":"CVE-2020-7494","kev_date_added":null,"published":"2020-06-16"},{"cvss_score":7,"headline":"Security feature bypass in EcoStruxure Operator Terminal Expert","id":"CVE-2022-41666","kev_date_added":null,"published":"2022-11-04"},{"cvss_score":7,"headline":"Path traversal in EcoStruxure Operator Terminal Expert","id":"CVE-2022-41667","kev_date_added":null,"published":"2022-11-04"}],"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":"Improper input validation in EcoStruxure and Pro-face HMI software allows arbitrary code execution when the Ethernet Download feature is enabled.","url":"https://insights.sbomify.com/CVE-2020-28221/"}
