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-2026-3893 in the wild and no public exploit code.\n\nAffected product: Carlson Software VASCO-B GNSS Receiver. 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-2026-3893/ (Markdown: https://insights.sbomify.com/CVE-2026-3893/index.md)","id":"CVE-2026-3893","markdown":"https://insights.sbomify.com/CVE-2026-3893/index.md","name":"CVE-2026-3893","record":{"aliases":["GHSA-fc84-9gcf-p72v"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"GNSS Receiver","requires_auth":"none","summary":"Attackers with network access can modify configuration and operational functions of the Carlson VASCO-B GNSS Receiver without authentication.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"The Carlson VASCO-B GNSS Receiver lacks an authentication mechanism, \nallowing an attacker with network access to directly access and modify \nits configuration and operational functions without needing credentials.","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":"Carlson Software VASCO-B GNSS Receiver Missing Authentication for Critical Function","id":"CVE-2026-3893","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Out-of-bounds Read vulnerability in RTI Connext Professional (Core Libraries) allows Overread Buffers.","id":"CVE-2026-3894"},"packages":[],"prev":{"headline":"Path traversal in Motors – Car Dealership \u0026 Classified Listings Plugin","id":"CVE-2026-3892"},"products":["VASCO-B GNSS Receiver"],"published":"2026-04-28","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":"partial"},"state":"PUBLISHED","updated":"2026-04-29","vendors":["Carlson Software"]},"summary":"Attackers with network access can modify configuration and operational functions of the Carlson VASCO-B GNSS Receiver without authentication.","url":"https://insights.sbomify.com/CVE-2026-3893/"}
