Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-3091 in the wild and no public exploit code.\n\nAffected product: Helmholz mbCONNECT24. 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-2025-3091/ (Markdown: https://insights.sbomify.com/CVE-2025-3091/index.md)","id":"CVE-2025-3091","markdown":"https://insights.sbomify.com/CVE-2025-3091/index.md","name":"CVE-2025-3091","record":{"aliases":["GHSA-3mpf-fhf9-62mx"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial connectivity platform","requires_auth":"low_privilege","summary":"An attacker with another user's second factor can bypass password authentication to log in as that user on the mbCONNECT24 platform.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"An low privileged remote attacker in possession of the second factor for another user can login as that user without knowledge of the other user`s password.","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":"MB connect line: Authorization bypass in mbCONNECT24/mymbCONNECT24","id":"CVE-2025-3091","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"MB connect line: Observable response discrepancy in mbCONNECT24/mymbCONNECT24","id":"CVE-2025-3092"},"packages":[],"prev":{"headline":"MB connect line: Missing Authentication in mbCONNECT24/mymbCONNECT24","id":"CVE-2025-3090"},"products":["mbCONNECT24","myREX24","myREX24.virtual","mymbCONNECT24"],"published":"2025-06-24","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":"total"},"state":"PUBLISHED","updated":"2025-06-24","vendors":["Helmholz","MB connect line"]},"summary":"An attacker with another user's second factor can bypass password authentication to log in as that user on the mbCONNECT24 platform.","url":"https://insights.sbomify.com/CVE-2025-3091/"}
