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-2024-42512 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- OPCFoundation.NetStandard.Opc.Ua.Core (NuGet): affected all versions; fixed in 1.5.374.158\n- OPCFoundation.NetStandard.Opc.Ua.Core (NuGet): affected all versions; fixed in 1.5.374.158\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-2024-42512/ (Markdown: https://insights.sbomify.com/CVE-2024-42512/index.md)","id":"CVE-2024-42512","markdown":"https://insights.sbomify.com/CVE-2024-42512/index.md","name":"CVE-2024-42512","record":{"aliases":["GHSA-h958-fxgg-g7w3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"OPC UA .NET library","requires_auth":"none","summary":"An attacker can bypass application authentication in OPC UA .NET Standard Stack if the deprecated Basic128Rsa15 security policy is enabled.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ua_.net_standard_stack","vendor":"opcfoundation"}],"cvss":{"score":8.6,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-208","name":"Observable Timing Discrepancy"}],"description":"Vulnerability in the OPC UA .NET Standard Stack before 1.5.374.158 allows an unauthorized attacker to bypass application authentication when the deprecated Basic128Rsa15 security policy is enabled.","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":"Security Update for the OPC UA .NET Standard Stack","id":"CVE-2024-42512","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"auth_bypass","year":"2024"},"n_packages":2,"n_references":1,"next":{"headline":"Security Update for the OPC UA .NET Standard Stack","id":"CVE-2024-42513"},"packages":[{"ecosystem":"NuGet","fixed":["1.5.374.158"],"introduced":["0"],"last_affected":[],"package":"OPCFoundation.NetStandard.Opc.Ua.Core","purl":null,"source":"GHSA-h958-fxgg-g7w3"},{"ecosystem":"NuGet","fixed":["1.5.374.158"],"introduced":["0"],"last_affected":[],"package":"OPCFoundation.NetStandard.Opc.Ua.Core","purl":"pkg:nuget/OPCFoundation.NetStandard.Opc.Ua.Core","source":"GHSA-h958-fxgg-g7w3"}],"prev":{"headline":"Unauthenticated Command Injection Vulnerability in the CLI Service Accessed by the PAPI Protocol","id":"CVE-2024-42509"},"products":["n/a"],"published":"2025-02-10","related":[{"cvss_score":7.5,"headline":"Exposure of Sensitive Information in OPCFoundation.NetStandard.Opc.Ua.Server","id":"CVE-2022-33916","kev_date_added":null,"published":"2022-08-23"},{"cvss_score":7.5,"headline":"Security Update for the OPC UA .NET Standard Stack","id":"CVE-2022-29862","kev_date_added":null,"published":"2022-06-16"},{"cvss_score":7.5,"headline":"Memory Allocation with Excessive Size Value in OPCFoundation.NetStandard.Opc.Ua.Core","id":"CVE-2022-29863","kev_date_added":null,"published":"2022-06-16"},{"cvss_score":7.5,"headline":"Uncontrolled Resource Consumption in OPCFoundation.NetStandard.Opc.Ua.Core","id":"CVE-2022-29864","kev_date_added":null,"published":"2022-06-16"},{"cvss_score":7.5,"headline":"Incorrect Implementation of Authentication Algorithm in OPCFoundation.NetStandard.Opc.Ua.Core","id":"CVE-2022-29865","kev_date_added":null,"published":"2022-06-16"},{"cvss_score":7.5,"headline":"Uncontrolled Resource Consumption in OPCFoundation.NetStandard.Opc.Ua.Core","id":"CVE-2022-29866","kev_date_added":null,"published":"2022-06-16"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["n/a"]},"summary":"An attacker can bypass application authentication in OPC UA .NET Standard Stack if the deprecated Basic128Rsa15 security policy is enabled.","url":"https://insights.sbomify.com/CVE-2024-42512/"}
