An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-41767 in the wild and no public exploit code.\n\nAffected product: MBS UBR-01 Mk II. 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-2025-41767/ (Markdown: https://insights.sbomify.com/CVE-2025-41767/index.md)","id":"CVE-2025-41767","markdown":"https://insights.sbomify.com/CVE-2025-41767/index.md","name":"CVE-2025-41767","record":{"aliases":["GHSA-6hp4-rq8j-6v6j"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"UBR network device","requires_auth":"high_privilege","summary":"High-privileged attackers can compromise UBR devices by bypassing update signature checks in the web interface.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"universal_bacnet_router_firmware","vendor":"mbs-solutions"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"A high-privileged remote attacker can fully compromise the device by abusing an update signature bypass vulnerability in the wwwupdate.cgi method in the web interface of UBR.","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":"Signature bypass on update upload","id":"CVE-2025-41767","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Beckhoff: XSS Vulnerability in TwinCAT 3 HMI Server","id":"CVE-2025-41768"},"packages":[],"prev":{"headline":"Stack buffer overflow on parsing web request","id":"CVE-2025-41766"},"products":["UBR-01 Mk II","UBR-02","UBR-LON"],"published":"2026-03-09","related":[{"cvss_score":9.1,"headline":"Unchecked role in wwwupdate.cgi","id":"CVE-2025-41764","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":9.1,"headline":"Unchecked role in wwwupload.cgi","id":"CVE-2025-41765","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":8.8,"headline":"Arbitrary Write with ubr-restore","id":"CVE-2025-41757","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":8.8,"headline":"Arbitrary Write with wwwupload.cgi","id":"CVE-2025-41758","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":8.8,"headline":"Stack buffer overflow on parsing web request","id":"CVE-2025-41766","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":8.1,"headline":"Arbitrary Write with ubr-editfile","id":"CVE-2025-41756","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":7.8,"headline":"Privilege escalation possible","id":"CVE-2025-41761","kev_date_added":null,"published":"2026-03-09"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-09","vendors":["MBS"]},"summary":"High-privileged attackers can compromise UBR devices by bypassing update signature checks in the web interface.","url":"https://insights.sbomify.com/CVE-2025-41767/"}
