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-2020-15806 in the wild and no public exploit code.\n\nAffected product: Codesys Control Runtime System Toolkit. 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-2020-15806/ (Markdown: https://insights.sbomify.com/CVE-2020-15806/index.md)","id":"CVE-2020-15806","markdown":"https://insights.sbomify.com/CVE-2020-15806/index.md","name":"CVE-2020-15806","record":{"aliases":["GHSA-fp2p-fx97-wr62"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CODESYS Control runtime","requires_auth":"none","summary":"An attacker can cause a denial of service in CODESYS Control runtime systems through uncontrolled memory allocation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"control_for_beaglebone","vendor":"codesys"},{"product":"control_for_empc-a\\/imx6","vendor":"codesys"},{"product":"control_for_iot2000","vendor":"codesys"},{"product":"control_for_linux","vendor":"codesys"},{"product":"control_for_pfc100","vendor":"codesys"},{"product":"control_for_pfc200","vendor":"codesys"},{"product":"control_for_plcnext","vendor":"codesys"},{"product":"control_for_raspberry_pi","vendor":"codesys"},{"product":"control_for_wago_touch_panels_600","vendor":"codesys"},{"product":"control_rte","vendor":"codesys"},{"product":"control_runtime_system_toolkit","vendor":"codesys"},{"product":"control_win","vendor":"codesys"},{"product":"embedded_target_visu_toolkit","vendor":"codesys"},{"product":"hmi","vendor":"codesys"},{"product":"remote_target_visu_toolkit","vendor":"codesys"},{"product":"simulation_runtime","vendor":"codesys"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"CODESYS Control runtime system before 3.5.16.10 allows Uncontrolled Memory Allocation.","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":"Denial of service in n/a","id":"CVE-2020-15806","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"codesys:control_runtime_system_toolkit","products":["codesys:control_runtime_system_toolkit"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Null dereference in n/a","id":"CVE-2020-15807"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-15803"},"products":["n/a"],"published":"2020-07-22","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-10245","kev_date_added":null,"published":"2020-03-26"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-18858","kev_date_added":null,"published":"2019-11-20"},{"cvss_score":9.8,"headline":"Memory corruption in CODESYS V3 web server","id":"CVE-2019-13548","kev_date_added":null,"published":"2019-09-13"},{"cvss_score":8.8,"headline":"Codesys Runtime Improper Limitation of a Pathname","id":"CVE-2018-25048","kev_date_added":null,"published":"2023-03-23"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2019-9008","kev_date_added":null,"published":"2019-09-17"},{"cvss_score":7.8,"headline":"CODESYS V3 prone to Inadequate Password Hashing","id":"CVE-2020-12069","kev_date_added":null,"published":"2022-12-26"},{"cvss_score":7.5,"headline":"CODESYS V3: CmpBlkDrvTcp allows unauthenticated attackers to block all its available TCP connections","id":"CVE-2022-30791","kev_date_added":null,"published":"2022-07-11"}],"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 cause a denial of service in CODESYS Control runtime systems through uncontrolled memory allocation.","url":"https://insights.sbomify.com/CVE-2020-15806/"}
