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-2023-31048 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 1.4.371.86\n- OPCFoundation.NetStandard.Opc.Ua.Core (NuGet): affected all versions; fixed in 1.4.371.86\n- OPCFoundation.NetStandard.Opc.Ua.Server (NuGet): affected all versions; fixed in 1.4.371.86\n- OPCFoundation.NetStandard.Opc.Ua.Server (NuGet): affected all versions; fixed in 1.4.371.86\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-2023-31048/ (Markdown: https://insights.sbomify.com/CVE-2023-31048/index.md)","id":"CVE-2023-31048","markdown":"https://insights.sbomify.com/CVE-2023-31048/index.md","name":"CVE-2023-31048","record":{"aliases":["GHSA-4cvp-hr63-822j"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OPC UA .NET library","requires_auth":"none","summary":"Attackers can view sensitive information via remote error messages in the OPC UA .NET Standard Reference Server library.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ua-.netstandard","vendor":"opcfoundation"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-209","name":"Generation of Error Message Containing Sensitive Information"}],"description":"The OPC UA .NET Standard Reference Server before 1.4.371.86. places sensitive information into an error message that may be seen remotely.","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":"Exposure of Sensitive Information in OPC UA .NET Standard Reference Server","id":"CVE-2023-31048","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":4,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2023-31056"},"packages":[{"ecosystem":"NuGet","fixed":["1.4.371.86"],"introduced":["0"],"last_affected":[],"package":"OPCFoundation.NetStandard.Opc.Ua.Core","purl":null,"source":"GHSA-4cvp-hr63-822j"},{"ecosystem":"NuGet","fixed":["1.4.371.86"],"introduced":["0"],"last_affected":[],"package":"OPCFoundation.NetStandard.Opc.Ua.Core","purl":"pkg:nuget/OPCFoundation.NetStandard.Opc.Ua.Core","source":"GHSA-4cvp-hr63-822j"},{"ecosystem":"NuGet","fixed":["1.4.371.86"],"introduced":["0"],"last_affected":[],"package":"OPCFoundation.NetStandard.Opc.Ua.Server","purl":null,"source":"GHSA-4cvp-hr63-822j"},{"ecosystem":"NuGet","fixed":["1.4.371.86"],"introduced":["0"],"last_affected":[],"package":"OPCFoundation.NetStandard.Opc.Ua.Server","purl":"pkg:nuget/OPCFoundation.NetStandard.Opc.Ua.Server","source":"GHSA-4cvp-hr63-822j"}],"prev":{"headline":"Django bypasses validation when using one form field to upload multiple files","id":"CVE-2023-31047"},"products":["n/a"],"published":"2023-12-12","related":[{"cvss_score":7.5,"headline":"OPC Foundation UA .NET Standard ConditionRefresh Resource Exhaustion Denial-of-Service Vulnerability","id":"CVE-2023-27321","kev_date_added":null,"published":"2024-05-07"},{"cvss_score":4.4,"headline":"Improper Certificate Validation in OPCFoundation.NetStandard.Opc.Ua.Core","id":"CVE-2020-29457","kev_date_added":null,"published":"2021-02-16"}],"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":"2024-10-09","vendors":["n/a"]},"summary":"Attackers can view sensitive information via remote error messages in the OPC UA .NET Standard Reference Server library.","url":"https://insights.sbomify.com/CVE-2023-31048/"}
