It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-12087 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-2018-12087/ (Markdown: https://insights.sbomify.com/CVE-2018-12087/index.md)","id":"CVE-2018-12087","markdown":"https://insights.sbomify.com/CVE-2018-12087/index.md","name":"CVE-2018-12087","record":{"aliases":["GHSA-8336-mxp6-v5h9"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"OPC UA Client Library","requires_auth":"none","summary":"Attackers can decrypt passwords in OPC UA Client Applications if certificate validation is disabled during insecure communication.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ua-.net-legacy","vendor":"opcfoundation"},{"product":"ua-.netstandard","vendor":"opcfoundation"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Failure to validate certificates in OPC Foundation UA Client Applications communicating without security allows attackers with control over a piece of network infrastructure to decrypt passwords.","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Moderate severity vulnerability that affects OPCFoundation.NetStandard.Opc.Ua","id":"CVE-2018-12087","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"weak_cryptography","year":"2018"},"n_packages":2,"n_references":1,"next":{"headline":"Other in n/a","id":"CVE-2018-12088"},"packages":[{"ecosystem":"NuGet","fixed":["1.4.353.15"],"introduced":["0"],"last_affected":[],"package":"OPCFoundation.NetStandard.Opc.Ua","purl":null,"source":"GHSA-8336-mxp6-v5h9"},{"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-8336-mxp6-v5h9"}],"prev":{"headline":"High severity vulnerability that affects OPCFoundation.NetStandard.Opc.Ua","id":"CVE-2018-12086"},"products":["n/a"],"published":"2018-10-03","related":[{"cvss_score":8.8,"headline":"Supply chain in n/a","id":"CVE-2017-12070","kev_date_added":null,"published":"2018-06-14"},{"cvss_score":8.2,"headline":"XML external entity in n/a","id":"CVE-2018-12585","kev_date_added":null,"published":"2018-09-14"},{"cvss_score":7.5,"headline":"Denial of service in OPC Foundation OPC UA .NET Standard and OPC UA .NET Legacy","id":"CVE-2021-27432","kev_date_added":null,"published":"2021-05-20"},{"cvss_score":5.3,"headline":"OPC UA applications can allow a remote attacker to determine a Server's private key","id":"CVE-2018-7559","kev_date_added":null,"published":"2018-06-13"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can decrypt passwords in OPC UA Client Applications if certificate validation is disabled during insecure communication.","url":"https://insights.sbomify.com/CVE-2018-12087/"}
