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-2025-7390 in the wild and no public exploit code.\n\nAffected product: Softing OPC UA C++ SDK. 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-2025-7390/ (Markdown: https://insights.sbomify.com/CVE-2025-7390/index.md)","id":"CVE-2025-7390","markdown":"https://insights.sbomify.com/CVE-2025-7390/index.md","name":"CVE-2025-7390","record":{"aliases":["GHSA-6g5p-c2f9-9435"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"OPC UA SDK","requires_auth":"none","summary":"Attackers can bypass client certificate trust checks in OPC UA servers configured for secure communication, undermining authentication integrity.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Softing","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"A malicious client can bypass the client certificate trust check of an opc.https server when the server endpoint is configured to allow only secure communication.","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":"Bypass the client certificate trust check of an opc.https server while only secure communication is allowed","id":"CVE-2025-7390","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Cookies Addons - Moderately critical - Cross-site Scripting - SA-CONTRIB-2025-087","id":"CVE-2025-7392"},"packages":[],"prev":{"headline":"Unauthorized Arbitrary File Read via RMI in AdminServer Interface","id":"CVE-2025-7389"},"products":["OPC UA C++ SDK","edgeAggregator","edgeConnector"],"published":"2025-08-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"total"},"state":"PUBLISHED","updated":"2026-03-27","vendors":["Softing"]},"summary":"Attackers can bypass client certificate trust checks in OPC UA servers configured for secure communication, undermining authentication integrity.","url":"https://insights.sbomify.com/CVE-2025-7390/"}
