An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-5000 in the wild and no public exploit code.\n\nAffected product: CODESYS Control RTE (SL). 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-2024-5000/ (Markdown: https://insights.sbomify.com/CVE-2024-5000/index.md)","id":"CVE-2024-5000","markdown":"https://insights.sbomify.com/CVE-2024-5000/index.md","name":"CVE-2024-5000","record":{"aliases":["GHSA-xchm-28cx-p56h"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CODESYS OPC UA","requires_auth":"none","summary":"An unauthenticated remote attacker can cause a denial of service on CODESYS OPC UA products by sending a crafted request that triggers a buffer size calculation error.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-131","name":"Incorrect Calculation of Buffer Size"}],"description":"An unauthenticated remote attacker can use a malicious OPC UA client to send a crafted request to affected CODESYS products which can cause a DoS due to incorrect calculation of buffer size.","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: Incorrect calculation of buffer size can cause DoS on CODESYS OPC UA products","id":"CVE-2024-5000","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Image Hover Effects for Elementor with Lightbox and Flipbox","id":"CVE-2024-5001"},"packages":[],"prev":{"headline":"Ligowave Unity/Pro/Mimo/APC Arbitrary Command Injection","id":"CVE-2024-4999"},"products":["CODESYS Control RTE (SL)","CODESYS Control RTE (for Beckhoff CX) SL","CODESYS Control Win (SL)","CODESYS Control for BeagleBone SL","CODESYS Control for IOT2000 SL","CODESYS Control for Linux ARM SL","CODESYS Control for Linux SL","CODESYS Control for PFC100 SL","CODESYS Control for PFC200 SL","CODESYS Control for PLCnext SL","CODESYS Control for Raspberry Pi SL","CODESYS Control for WAGO Touch Panels 600 SL","CODESYS Control for emPC-A/iMX6 SL","CODESYS HMI (SL)","CODESYS Runtime Toolkit"],"published":"2024-06-04","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-01","vendors":["CODESYS"]},"summary":"An unauthenticated remote attacker can cause a denial of service on CODESYS OPC UA products by sending a crafted request that triggers a buffer size calculation error.","url":"https://insights.sbomify.com/CVE-2024-5000/"}
