An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-3663 in the wild and no public exploit code.\n\nAffected product: CODESYS Development System. 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-2023-3663/ (Markdown: https://insights.sbomify.com/CVE-2023-3663/index.md)","id":"CVE-2023-3663","markdown":"https://insights.sbomify.com/CVE-2023-3663/index.md","name":"CVE-2023-3663","record":{"aliases":["GHSA-c86m-wfx2-qmx9"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"CODESYS Development System","requires_auth":"none","summary":"An unauthenticated remote attacker can manipulate HTTP notification content in CODESYS Development System due to missing integrity checks.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"development_system","vendor":"codesys"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-940","name":"Improper Verification of Source of a Communication Channel"}],"description":"In CODESYS Development System versions from 3.5.11.20 and before 3.5.19.20 a missing integrity check might allow an unauthenticated remote attacker to manipulate the content of notifications received via HTTP by the CODESYS notification server.","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":"CODESYS: Missing integrity check in CODESYS Development System","id":"CVE-2023-3663","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"FileOrganizer \u003c= 1.0.2 - Admin+ Arbitrary File Access","id":"CVE-2023-3664"},"packages":[],"prev":{"headline":"CODESYS: Vulnerability in CODESYS Development System allows for execution of binaries","id":"CVE-2023-3662"},"products":["CODESYS Development System"],"published":"2023-08-03","related":[{"cvss_score":8.8,"headline":"Deserialization in CODESYS","id":"CVE-2021-21863","kev_date_added":null,"published":"2021-08-05"},{"cvss_score":8.8,"headline":"Deserialization in CODESYS","id":"CVE-2021-21865","kev_date_added":null,"published":"2021-08-02"},{"cvss_score":8.8,"headline":"Deserialization in CODESYS","id":"CVE-2021-21866","kev_date_added":null,"published":"2021-08-02"},{"cvss_score":8.5,"headline":"Incorrect Default Permissions in CODESYS Development System","id":"CVE-2026-44468","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":8.5,"headline":"Incorrect Default Permissions in CODESYS Development System","id":"CVE-2026-44469","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":7.8,"headline":"Deserialization in CODESYS","id":"CVE-2021-21864","kev_date_added":null,"published":"2021-08-02"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-27","vendors":["CODESYS"]},"summary":"An unauthenticated remote attacker can manipulate HTTP notification content in CODESYS Development System due to missing integrity checks.","url":"https://insights.sbomify.com/CVE-2023-3663/"}
