It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-22705 and fix it if it is affected.\n\nWhat it is: CVE-2021-22705 is a high-severity memory corruption vulnerability in Harmony HMI Products Configured by Vijeo Designer (all versions prior to V6.2 SP11 ) or EcoStruxure Machine Expert (all versions prior to V2.0), published on 26 May 2021. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-22705 in the wild and no public exploit code.\n\nAffected product: Harmony HMI Products Configured by Vijeo Designer (all versions prior to V6.2 SP11 ) or EcoStruxure Machine Expert (all versions prior to V2.0). 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-2021-22705/ (Markdown: https://insights.sbomify.com/CVE-2021-22705/index.md)","id":"CVE-2021-22705","markdown":"https://insights.sbomify.com/CVE-2021-22705/index.md","name":"CVE-2021-22705","record":{"aliases":["GHSA-j25f-486x-cqmj"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HMI configuration software","requires_auth":"low_privilege","summary":"Attackers can cause denial of service or read system information via improper memory buffer handling in Vijeo Designer or EcoStruxure Machine Expert drivers.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"ecostruxure_machine_expert","vendor":"schneider-electric"},{"product":"vijeo_designer","vendor":"schneider-electric"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability exists that could cause denial of service or unauthorized access to system information when interacting directly with a driver installed by Vijeo Designer or EcoStruxure Machine Expert","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":"Memory corruption in Harmony HMI Products Configured by Vijeo Designer (all versions prior to V6.2 SP11 ) or EcoStruxure Machine Expert (all versions prior to V2.0)","id":"CVE-2021-22705","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in EVlink City (EVC1S22P4 / EVC1S7P4 all versions prior to R8 V3.4.0.1), EVlink Parking (EVW2 / EVF2 / EV.2 all versions prior to R8 V3.4.0.1), and EVlink Smart Wallbox (EVB1A all versions prior to R8 V3.4.0.1 )","id":"CVE-2021-22706"},"packages":[],"prev":{"headline":"Path traversal in Harmony/HMI Products Configured by Vijeo Designer (all versions prior to V6.2 SP11 ), Vijeo Designer Basic (all versions prior to V1.2), or EcoStruxure Machine Expert (all versions prior to V2.0)","id":"CVE-2021-22704"},"products":["Harmony HMI Products Configured by Vijeo Designer (all versions prior to V6.2 SP11 ) or EcoStruxure Machine Expert (all versions prior to V2.0)"],"published":"2021-05-26","related":[{"cvss_score":9.8,"headline":"Code injection in EcoStruxure Machine Expert (all versions)SoMachine, SoMachine Motion (all versions)Modicon M218 Logic Controller (all versions)Modicon M241 Logic Controller (all versions)Modicon M251 Logic Controller (all versions)Modicon M258 Logic Controller (all versions)","id":"CVE-2020-7487","kev_date_added":null,"published":"2020-04-22"},{"cvss_score":9.8,"headline":"Code injection in SoMachine Basic (all versions)EcoStruxure Machine Expert – Basic (all versions)Modicon M100 Logic Controller (all versions)Modicon M200 Logic Controller (all versions)Modicon M221 Logic Controller (all versions)","id":"CVE-2020-7489","kev_date_added":null,"published":"2020-04-22"},{"cvss_score":9.1,"headline":"Path traversal in Harmony/HMI Products Configured by Vijeo Designer (all versions prior to V6.2 SP11 ), Vijeo Designer Basic (all versions prior to V1.2), or EcoStruxure Machine Expert (all versions prior to V2.0)","id":"CVE-2021-22704","kev_date_added":null,"published":"2021-09-02"},{"cvss_score":7.5,"headline":"Information disclosure in EcoStruxure Machine Expert (all versions)SoMachine, SoMachine Motion (all versions)Modicon M218 Logic Controller (all versions)Modicon M241 Logic Controller (all versions)Modicon M251 Logic Controller (all versions)Modicon M258 Logic Controller (all versions)","id":"CVE-2020-7488","kev_date_added":null,"published":"2020-04-22"}],"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":["n/a"]},"summary":"Attackers can cause denial of service or read system information via improper memory buffer handling in Vijeo Designer or EcoStruxure Machine Expert drivers.","url":"https://insights.sbomify.com/CVE-2021-22705/"}
