An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-22668 and fix it if it is affected.\n\nWhat it is: CVE-2021-22668 is a critical memory corruption vulnerability in Delta Industrial Automation CNCSoft ScreenEditor, published on 16 May 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-2021-22668 in the wild and no public exploit code.\n\nAffected product: Delta Industrial Automation CNCSoft ScreenEditor. 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-2021-22668/ (Markdown: https://insights.sbomify.com/CVE-2021-22668/index.md)","id":"CVE-2021-22668","markdown":"https://insights.sbomify.com/CVE-2021-22668/index.md","name":"CVE-2021-22668","record":{"aliases":["GHSA-pr9v-hc3w-247x"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"CNCSoft ScreenEditor","requires_auth":"none","summary":"An out-of-bounds read in Delta CNCSoft ScreenEditor allows attackers to execute arbitrary code via malicious project files.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"cncsoft_screeneditor","vendor":"deltaww"}],"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-125","name":"Out-of-bounds Read"}],"description":"Delta Industrial Automation CNCSoft ScreenEditor Versions 1.01.28 (with ScreenEditor Version 1.01.2) and prior are vulnerable to an out-of-bounds read while processing project files, which may allow an attacker to execute arbitrary code.","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 Delta Industrial Automation CNCSoft ScreenEditor","id":"CVE-2021-22668","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":"Privilege escalation in Advantech WebAccess/SCADA","id":"CVE-2021-22669"},"packages":[],"prev":{"headline":"Hardcoded credentials in BB-ESWGP506-2SFP-T","id":"CVE-2021-22667"},"products":["Delta Industrial Automation CNCSoft ScreenEditor"],"published":"2021-05-16","related":[{"cvss_score":7.8,"headline":"Memory corruption in Delta Electronics CNCSoft ScreenEditor","id":"CVE-2021-22672","kev_date_added":null,"published":"2021-05-10"},{"cvss_score":7.8,"headline":"Memory corruption in Delta Electronics CNCSoft ScreenEditor","id":"CVE-2020-27281","kev_date_added":null,"published":"2021-01-11"},{"cvss_score":7.8,"headline":"Memory corruption in Delta Industrial Automation CNCSoft ScreenEditor","id":"CVE-2020-16199","kev_date_added":null,"published":"2020-08-04"},{"cvss_score":7.8,"headline":"Null dereference in Delta Industrial Automation CNCSoft ScreenEditor","id":"CVE-2020-16203","kev_date_added":null,"published":"2020-08-04"},{"cvss_score":7.8,"headline":"Memory corruption in Delta Industrial Automation CNCSoft ScreenEditor","id":"CVE-2020-7002","kev_date_added":null,"published":"2020-03-18"},{"cvss_score":7.8,"headline":"Memory corruption in Delta Industrial Automation CNCSoft","id":"CVE-2019-10947","kev_date_added":null,"published":"2019-04-17"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"An out-of-bounds read in Delta CNCSoft ScreenEditor allows attackers to execute arbitrary code via malicious project files.","url":"https://insights.sbomify.com/CVE-2021-22668/"}
