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-2021-22756 in the wild and no public exploit code.\n\nAffected product: IGSS Definition (Def.exe) V15.0.0.21140 and prior. 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-2021-22756/ (Markdown: https://insights.sbomify.com/CVE-2021-22756/index.md)","id":"CVE-2021-22756","markdown":"https://insights.sbomify.com/CVE-2021-22756/index.md","name":"CVE-2021-22756","record":{"aliases":["GHSA-vj4w-gfgg-xvgv"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["data_read","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IGSS Definition","requires_auth":"none","summary":"Out-of-bounds read in IGSS Definition allows information disclosure or remote code execution via malicious CGF files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"interactive_graphical_scada_system","vendor":"schneider-electric"}],"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-125","name":"Out-of-bounds Read"}],"description":"A CWE-125: Out-of-bounds read vulnerability exists inIGSS Definition (Def.exe) V15.0.0.21140 and prior that could result in disclosure of information or remote code execution due to lack of user-supplied data validation, when a malicious CGF file is imported to IGSS Definition.","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 IGSS Definition (Def.exe) V15.0.0.21140 and prior","id":"CVE-2021-22756","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":"Memory corruption in IGSS Definition (Def.exe) V15.0.0.21140 and prior","id":"CVE-2021-22757"},"packages":[],"prev":{"headline":"Memory corruption in IGSS Definition (Def.exe) V15.0.0.21140 and prior","id":"CVE-2021-22755"},"products":["IGSS Definition (Def.exe) V15.0.0.21140 and prior"],"published":"2021-06-11","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2013-0657","kev_date_added":null,"published":"2013-01-21"},{"cvss_score":9.8,"headline":"Integer overflow in IGSS Data Server (IGSSdataServer.exe)","id":"CVE-2022-2329","kev_date_added":null,"published":"2023-02-01"},{"cvss_score":9.8,"headline":"Memory corruption in IGSS Data Server (IGSSdataServer.exe)","id":"CVE-2022-24324","kev_date_added":null,"published":"2023-02-01"},{"cvss_score":9.8,"headline":"Memory corruption in IGSS Data Server (IGSSdataServer.exe)","id":"CVE-2022-32522","kev_date_added":null,"published":"2023-01-30"},{"cvss_score":9.8,"headline":"Memory corruption in IGSS Data Server (IGSSdataServer.exe)","id":"CVE-2022-32523","kev_date_added":null,"published":"2023-01-30"},{"cvss_score":9.8,"headline":"Memory corruption in IGSS Data Server (IGSSdataServer.exe)","id":"CVE-2022-32524","kev_date_added":null,"published":"2023-01-30"},{"cvss_score":9.8,"headline":"Memory corruption in IGSS Data Server (IGSSdataServer.exe)","id":"CVE-2022-32525","kev_date_added":null,"published":"2023-01-30"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"Out-of-bounds read in IGSS Definition allows information disclosure or remote code execution via malicious CGF files.","url":"https://insights.sbomify.com/CVE-2021-22756/"}
