Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-41766 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-2025-41766/ (Markdown: https://insights.sbomify.com/CVE-2025-41766/index.md)","id":"CVE-2025-41766","markdown":"https://insights.sbomify.com/CVE-2025-41766/index.md","name":"CVE-2025-41766","record":{"aliases":["GHSA-fp48-r694-65jv"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"UBR network device","requires_auth":"low_privilege","summary":"A remote attacker can achieve full device compromise via a stack buffer overflow in the web request parser.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"universal_bacnet_router_firmware","vendor":"mbs-solutions"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A low-privileged remote attacker can trigger a stack-based buffer overflow via a crafted HTTP POST request using the ubr-network method resulting in full device compromise.","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":"Stack buffer overflow on parsing web request","id":"CVE-2025-41766","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Signature bypass on update upload","id":"CVE-2025-41767"},"packages":[],"prev":{"headline":"Unchecked role in wwwupload.cgi","id":"CVE-2025-41765"},"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":8.1,"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":"A remote attacker can achieve full device compromise via a stack buffer overflow in the web request parser.","url":"https://insights.sbomify.com/CVE-2025-41766/"}
