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-2018-12086 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- OPCFoundation.NetStandard.Opc.Ua (NuGet): affected all versions; fixed in 1.4.353.15\n- OPCFoundation.NetStandard.Opc.Ua (NuGet): affected all versions; fixed in 1.4.353.15\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-2018-12086/ (Markdown: https://insights.sbomify.com/CVE-2018-12086/index.md)","id":"CVE-2018-12086","markdown":"https://insights.sbomify.com/CVE-2018-12086/index.md","name":"CVE-2018-12086","record":{"aliases":["DEBIAN-CVE-2018-12086","GHSA-782p-53wq-cxmj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OPC UA library","requires_auth":"none","summary":"Remote attackers can trigger a stack overflow via crafted requests, potentially leading to code execution or denial of service in OPC UA applications.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"unified_architecture-.net-legacy","vendor":"opcfoundation"},{"product":"unified_architecture-java","vendor":"opcfoundation"},{"product":"unified_architecture_.net-standard","vendor":"opcfoundation"},{"product":"unified_architecture_ansic","vendor":"opcfoundation"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Buffer overflow in OPC UA applications allows remote attackers to trigger a stack overflow with carefully structured requests.","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":"2019-02-20","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2019-02-20T16:11:26Z","kind":"github_poc","ref":"https://github.com/kevinherron/stack-overflow-poc","stars":0,"title":"PoC for CVE-2018-12086 affecting various OPC UA stacks"}],"tier":"poc_unverified"},"has_fix":true,"headline":"High severity vulnerability that affects OPCFoundation.NetStandard.Opc.Ua","id":"CVE-2018-12086","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"memory_corruption","year":"2018"},"n_packages":2,"n_references":5,"next":{"headline":"Moderate severity vulnerability that affects OPCFoundation.NetStandard.Opc.Ua","id":"CVE-2018-12087"},"packages":[{"ecosystem":"NuGet","fixed":["1.4.353.15"],"introduced":["0"],"last_affected":[],"package":"OPCFoundation.NetStandard.Opc.Ua","purl":null,"source":"GHSA-782p-53wq-cxmj"},{"ecosystem":"NuGet","fixed":["1.4.353.15"],"introduced":["0"],"last_affected":[],"package":"OPCFoundation.NetStandard.Opc.Ua","purl":"pkg:nuget/OPCFoundation.NetStandard.Opc.Ua","source":"GHSA-782p-53wq-cxmj"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2018-12085"},"products":["n/a"],"published":"2018-09-14","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can trigger a stack overflow via crafted requests, potentially leading to code execution or denial of service in OPC UA applications.","url":"https://insights.sbomify.com/CVE-2018-12086/"}
