Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-41757 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-2025-41757/ (Markdown: https://insights.sbomify.com/CVE-2025-41757/index.md)","id":"CVE-2025-41757","markdown":"https://insights.sbomify.com/CVE-2025-41757/index.md","name":"CVE-2025-41757","record":{"aliases":["GHSA-jc3h-m5q6-x7vp"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"UBR backup appliance","requires_auth":"low_privilege","summary":"Low-privileged attackers can exploit unvalidated backup restoration to overwrite arbitrary system files, leading to code execution and privilege escalation.","user_interaction":"not_required","vuln_class":"path_traversal"},"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-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A low-privileged remote attacker can abuse the backup restore functionality of UBR (ubr-restore) which runs with elevated privileges and does not validate the contents of the backup archive to create or overwrite arbitrary files anywhere on the system.","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":"Arbitrary Write with ubr-restore","id":"CVE-2025-41757","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Arbitrary Write with wwwupload.cgi","id":"CVE-2025-41758"},"packages":[],"prev":{"headline":"Arbitrary Write with ubr-editfile","id":"CVE-2025-41756"},"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 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":"Low-privileged attackers can exploit unvalidated backup restoration to overwrite arbitrary system files, leading to code execution and privilege escalation.","url":"https://insights.sbomify.com/CVE-2025-41757/"}
