Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-34574 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-2021-34574/ (Markdown: https://insights.sbomify.com/CVE-2021-34574/index.md)","id":"CVE-2021-34574","markdown":"https://insights.sbomify.com/CVE-2021-34574/index.md","name":"CVE-2021-34574","record":{"aliases":["GHSA-c4j8-5xv4-xcxh"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial IoT platform","requires_auth":"low_privilege","summary":"Authenticated attackers can bypass password policy restrictions by intercepting and modifying password change requests in MB connect line and Helmholz products.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"myrex24","vendor":"helmholz"},{"product":"myrex24.virtual","vendor":"helmholz"},{"product":"mbconnect24","vendor":"mbconnectline"},{"product":"mymbconnect24","vendor":"mbconnectline"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-669","name":"Incorrect Resource Transfer Between Spheres"}],"description":"In MB connect line mymbCONNECT24, mbCONNECT24 and Helmholz myREX24 and myREX24.virtual in all versions through v2.11.2 an authenticated attacker can change the password of his account into a new password that violates the password policy by intercepting and modifying the request that is send to the server.","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":"Password policy evasion in products of MB connect line and Helmholz","id":"CVE-2021-34574","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Information Exposure in mymbCONNECT24, mbCONNECT24 \u003c= 2.8.0","id":"CVE-2021-34575"},"packages":[],"prev":{"headline":"Incorrect calculation in Enbra EWM does not report backflows or no flow events","id":"CVE-2021-34573"},"products":["mbCONNECT24","myREX24","myREX24.virtual","mymbCONNECT24"],"published":"2021-08-02","related":[{"cvss_score":7.5,"headline":"SSRF in products of MB connect line and Helmholz","id":"CVE-2020-35558","kev_date_added":null,"published":"2021-02-16"},{"cvss_score":6.5,"headline":"Improper Access Validation in products of MB connect line and Helmholz","id":"CVE-2020-12527","kev_date_added":null,"published":"2021-03-02"},{"cvss_score":6.5,"headline":"Improper Access Validation in products of MB connect line and Helmholz","id":"CVE-2020-35557","kev_date_added":null,"published":"2021-02-16"},{"cvss_score":5.3,"headline":"User enumeration vulnerability in MB connect line and Helmholz products","id":"CVE-2022-22520","kev_date_added":null,"published":"2022-09-14"},{"cvss_score":5.3,"headline":"SSRF in variuos products of MB connect line and Helmholz","id":"CVE-2020-35561","kev_date_added":null,"published":"2021-02-16"},{"cvss_score":5.3,"headline":"Local file inclusion vulnerability in products of MB connect line and Helmholz","id":"CVE-2020-35566","kev_date_added":null,"published":"2021-02-16"},{"cvss_score":5.3,"headline":"Foreced Browsing vulnerability in products of MB connect line and Helmholz","id":"CVE-2020-35570","kev_date_added":null,"published":"2021-02-16"}],"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":"2024-09-16","vendors":["Helmholz","MB connect line"]},"summary":"Authenticated attackers can bypass password policy restrictions by intercepting and modifying password change requests in MB connect line and Helmholz products.","url":"https://insights.sbomify.com/CVE-2021-34574/"}
