It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-27280 in the wild and no public exploit code.\n\nAffected product: ISPSoft. 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-2020-27280/ (Markdown: https://insights.sbomify.com/CVE-2020-27280/index.md)","id":"CVE-2020-27280","markdown":"https://insights.sbomify.com/CVE-2020-27280/index.md","name":"CVE-2020-27280","record":{"aliases":["GHSA-2wp4-vwq7-x2x6"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ISPSoft PLC programming","requires_auth":"none","summary":"A use-after-free vulnerability in ISPSoft allows attackers to execute arbitrary code via a specially crafted project file.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"ispsoft","vendor":"deltaww"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use after free issue has been identified in the way ISPSoft(v3.12 and prior) processes project files, allowing an attacker to craft a special project file that may allow arbitrary code execution.","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":"Use after free in ISPSoft","id":"CVE-2020-27280","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Delta Electronics CNCSoft ScreenEditor","id":"CVE-2020-27281"},"packages":[],"prev":{"headline":"A NULL pointer deference vulnerability has been identified in the protocol converter.","id":"CVE-2020-27279"},"products":["ISPSoft"],"published":"2021-01-26","related":[{"cvss_score":8.2,"headline":"Delta Electronics ISPSoft Heap Buffer-Overflow","id":"CVE-2023-5131","kev_date_added":null,"published":"2024-01-18"},{"cvss_score":7.8,"headline":"ISPSoft File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2025-22882","kev_date_added":null,"published":"2025-04-30"},{"cvss_score":7.8,"headline":"ISPSoft File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2025-22883","kev_date_added":null,"published":"2025-04-30"},{"cvss_score":7.8,"headline":"ISPSoft File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2025-22884","kev_date_added":null,"published":"2025-04-30"},{"cvss_score":7.8,"headline":"ISPSoft File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2025-4124","kev_date_added":null,"published":"2025-04-30"},{"cvss_score":7.8,"headline":"ISPSoft File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2025-4125","kev_date_added":null,"published":"2025-04-30"}],"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":"A use-after-free vulnerability in ISPSoft allows attackers to execute arbitrary code via a specially crafted project file.","url":"https://insights.sbomify.com/CVE-2020-27280/"}
