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-2020-27277 in the wild and no public exploit code.\n\nAffected product: Delta Electronics. 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-2020-27277/ (Markdown: https://insights.sbomify.com/CVE-2020-27277/index.md)","id":"CVE-2020-27277","markdown":"https://insights.sbomify.com/CVE-2020-27277/index.md","name":"CVE-2020-27277","record":{"aliases":["GHSA-g9mq-5vvv-88hf"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Delta Electronics DOPSoft","requires_auth":"none","summary":"An attacker can execute arbitrary code by tricking a user into opening a malicious project file in Delta Electronics DOPSoft.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"dopsoft","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-476","name":"NULL Pointer Dereference"},{"id":"CWE-822","name":"Untrusted Pointer Dereference"}],"description":"Delta Electronics DOPSoft Version 4.0.8.21 and prior has a null pointer dereference issue 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":"Null dereference in Delta Electronics","id":"CVE-2020-27277","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Hardcoded credentials in Hamilton Medical AG, T1-Ventillator","id":"CVE-2020-27278"},"packages":[],"prev":{"headline":"Auth bypass in SOOIL Developments CoLtd DiabecareRS,AnyDana-i,AnyDana-A","id":"CVE-2020-27276"},"products":["Delta Electronics"],"published":"2021-01-11","related":[{"cvss_score":7.8,"headline":"Delta Electronics DOPSoft 2 Improper Input Validation","id":"CVE-2021-38406","kev_date_added":"2022-08-25","published":"2021-09-17"},{"cvss_score":8.8,"headline":"Delta Electronics Delta Industrial Automation DOPSoft DPS File wTextLen Buffer Overflow Remote Code Execution","id":"CVE-2023-43818","kev_date_added":null,"published":"2024-01-18"},{"cvss_score":8.8,"headline":"Delta Electronics Delta Industrial Automation DOPSoft DPS File InitialMacroLen Buffer Overflow Remote Code Execution","id":"CVE-2023-43819","kev_date_added":null,"published":"2024-01-18"},{"cvss_score":8.8,"headline":"Memory corruption in DOPSoft","id":"CVE-2023-43820","kev_date_added":null,"published":"2024-01-18"},{"cvss_score":8.8,"headline":"Memory corruption in DOPSoft","id":"CVE-2023-43821","kev_date_added":null,"published":"2024-01-18"},{"cvss_score":8.8,"headline":"Delta Electronics Delta Industrial Automation DOPSoft DPS File wLogTitlesTimeLen Buffer Overflow Remote Code Execution","id":"CVE-2023-43822","kev_date_added":null,"published":"2024-01-18"},{"cvss_score":8.8,"headline":"Delta Electronics Delta Industrial Automation DOPSoft DPS File wTTitleLen Buffer Overflow Remote Code Execution","id":"CVE-2023-43823","kev_date_added":null,"published":"2024-01-18"}],"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":"An attacker can execute arbitrary code by tricking a user into opening a malicious project file in Delta Electronics DOPSoft.","url":"https://insights.sbomify.com/CVE-2020-27277/"}
