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-2021-34580 in the wild and no public exploit code.\n\nAffected product: 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-2021-34580/ (Markdown: https://insights.sbomify.com/CVE-2021-34580/index.md)","id":"CVE-2021-34580","markdown":"https://insights.sbomify.com/CVE-2021-34580/index.md","name":"CVE-2021-34580","record":{"aliases":["GHSA-v5p4-qxg5-3jh2"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"mbCONNECT24 web app","requires_auth":"none","summary":"Unauthenticated attackers can enumerate valid backend users by analyzing server responses to invalid login attempts in mbCONNECT24.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"mbconnect24","vendor":"mbconnectline"},{"product":"mymbconnect24","vendor":"mbconnectline"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"},{"id":"CWE-204","name":"Observable Response Discrepancy"}],"description":"In mymbCONNECT24, mbCONNECT24 \u003c= 2.9.0 an unauthenticated user can enumerate valid backend users by checking what kind of response the server sends for crafted invalid login attempts.","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":"Remote user enumeration in mymbCONNECT24, mbCONNECT24 \u003c= 2.9.0","id":"CVE-2021-34580","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"WAGO: Denial of Service vulnerability inside the OpenSSL implementation","id":"CVE-2021-34581"},"packages":[],"prev":{"headline":"PHOENIX CONTACT: FL MGUARD DM version 1.12.0 and 1.13.0 Improper Privilege Management","id":"CVE-2021-34579"},"products":["mbCONNECT24","mymbCONNECT24"],"published":"2021-10-27","related":[{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2020-35565","kev_date_added":null,"published":"2021-02-16"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2020-10383","kev_date_added":null,"published":"2020-04-14"},{"cvss_score":9.1,"headline":"MB connect line mbCONNECT24 vulnerable to an unauthenticated SQL injection in the setinfo Endpoint","id":"CVE-2026-33615","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":8.8,"headline":"Helmholz and MB Connect Line: Account takeover via password reset in multiple products","id":"CVE-2023-0985","kev_date_added":null,"published":"2023-06-06"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2020-10382","kev_date_added":null,"published":"2020-04-14"},{"cvss_score":7.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2020-35567","kev_date_added":null,"published":"2021-02-16"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2020-10384","kev_date_added":null,"published":"2020-04-14"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["MB connect line"]},"summary":"Unauthenticated attackers can enumerate valid backend users by analyzing server responses to invalid login attempts in mbCONNECT24.","url":"https://insights.sbomify.com/CVE-2021-34580/"}
