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-2023-49676 in the wild and no public exploit code.\n\nAffected product: CODESYS Development System V2.3. 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-2023-49676/ (Markdown: https://insights.sbomify.com/CVE-2023-49676/index.md)","id":"CVE-2023-49676","markdown":"https://insights.sbomify.com/CVE-2023-49676/index.md","name":"CVE-2023-49676","record":{"aliases":["GHSA-q4h3-rm8f-c8qr"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"CODESYS Development System","requires_auth":"none","summary":"An attacker can cause a denial of service by tricking a user into opening corrupted project files in the CODESYS Development System.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"An unauthenticated local attacker may trick a user to open corrupted project files to crash the system due to use after free vulnerability.","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: Use after free vulnerability through corrupted project files","id":"CVE-2023-49676","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Job Portal v1.0 - Multiple Unauthenticated SQL Injections (SQLi)","id":"CVE-2023-49677"},"packages":[],"prev":{"headline":"CODESYS: Out-of-bounds write through corrupted project files","id":"CVE-2023-49675"},"products":["CODESYS Development System V2.3"],"published":"2024-05-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["CODESYS"]},"summary":"An attacker can cause a denial of service by tricking a user into opening corrupted project files in the CODESYS Development System.","url":"https://insights.sbomify.com/CVE-2023-49676/"}
