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-2025-27257 in the wild and no public exploit code.\n\nAffected product: GE Vernova B30 Multilin. 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-2025-27257/ (Markdown: https://insights.sbomify.com/CVE-2025-27257/index.md)","id":"CVE-2025-27257","markdown":"https://insights.sbomify.com/CVE-2025-27257/index.md","name":"CVE-2025-27257","record":{"aliases":["GHSA-5v9q-jpv7-7w2m"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GE Vernova IED","requires_auth":"high_privilege","summary":"Authenticated attackers can bypass client-side firmware signature checks to install modified firmware on GE Vernova UR IED devices.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Nozomi","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Insufficient Verification of Data Authenticity vulnerability in GE Vernova UR IED family devices allows an authenticated user to install a modified firmware.\nThe firmware signature verification is enforced only on the client-side dedicated software Enervista UR Setup, allowing the integration check to be bypassed.","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":"Security feature bypass in B30 Multilin","id":"CVE-2025-27257","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":"Ericsson Network Manager: escalation of privilege vulnerability","id":"CVE-2025-27258"},"packages":[],"prev":{"headline":"Auth bypass in EnerVista UR Setup","id":"CVE-2025-27256"},"products":["B30 Multilin","B90 Multilin","C30 Multilin","C60 Multilin","C70 Multilin","C95 Multilin","D30 Multilin","D60 Multilin","F35 Multilin","F60 Multilin","G30 Multilin","G60 Multilin","L30 Multilin","L60 Multilin","L90 Multilin","M60 Multilin","N60 multilin","T35 Multilin","T60 Multilin"],"published":"2025-03-10","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-12","vendors":["GE Vernova"]},"summary":"Authenticated attackers can bypass client-side firmware signature checks to install modified firmware on GE Vernova UR IED devices.","url":"https://insights.sbomify.com/CVE-2025-27257/"}
