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-2021-42796 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-2021-42796/ (Markdown: https://insights.sbomify.com/CVE-2021-42796/index.md)","id":"CVE-2021-42796","markdown":"https://insights.sbomify.com/CVE-2021-42796/index.md","name":"CVE-2021-42796","record":{"aliases":["GHSA-w96c-3jm7-32vm"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"AVEVA Edge HMI","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary commands on AVEVA Edge HMI systems via the ExecuteCommand function.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"edge","vendor":"aveva"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"An issue was discovered in ExecuteCommand() in AVEVA Edge (formerly InduSoft Web Studio) versions R2020 and prior that allows unauthenticated arbitrary commands to be executed.","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":"Command injection in n/a","id":"CVE-2021-42796","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-2021-42797"},"packages":[],"prev":{"headline":"Server-side request forgery in n/a","id":"CVE-2021-42794"},"products":["n/a"],"published":"2023-12-16","related":[{"cvss_score":9.8,"headline":"Auth bypass in InduSoft Web Studio, and InTouch Edge HMI (formerly InTouch Machine Edition)","id":"CVE-2018-17914","kev_date_added":null,"published":"2018-11-02"},{"cvss_score":9.8,"headline":"Memory corruption in InduSoft Web Studio, and InTouch Edge HMI (formerly InTouch Machine Edition)","id":"CVE-2018-17916","kev_date_added":null,"published":"2018-11-02"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2021-42797","kev_date_added":null,"published":"2023-12-16"},{"cvss_score":5.3,"headline":"Server-side request forgery in n/a","id":"CVE-2021-42794","kev_date_added":null,"published":"2023-12-16"}],"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":"2024-10-07","vendors":["n/a"]},"summary":"Unauthenticated attackers can execute arbitrary commands on AVEVA Edge HMI systems via the ExecuteCommand function.","url":"https://insights.sbomify.com/CVE-2021-42796/"}
