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-2022-22520 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-2022-22520/ (Markdown: https://insights.sbomify.com/CVE-2022-22520/index.md)","id":"CVE-2022-22520","markdown":"https://insights.sbomify.com/CVE-2022-22520/index.md","name":"CVE-2022-22520","record":{"aliases":["GHSA-mwvc-vgg7-3665"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial IoT web service","requires_auth":"none","summary":"Remote attackers can enumerate valid users via the web service, exposing user accounts in MB connect line and Helmholz industrial IoT products.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-204","name":"Observable Response Discrepancy"}],"description":"A remote, unauthenticated attacker can enumerate valid users by sending specific requests to the webservice of MB connect line mymbCONNECT24, mbCONNECT24 and Helmholz myREX24 and myREX24.virtual in all versions through v2.11.2.","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":"User enumeration vulnerability in MB connect line and Helmholz products","id":"CVE-2022-22520","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege Escalation in Miele Benchmark Programming Tool","id":"CVE-2022-22521"},"packages":[],"prev":{"headline":"Special HTTP(s) Requests can cause a buffer-read causing a crash of the webserver and the runtime system.","id":"CVE-2022-22519"},"products":["mbCONNECT24","myREX24","myREX24.virtual","mymbCONNECT24"],"published":"2022-09-14","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":"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":"2024-09-17","vendors":["Helmholz","MB connect line"]},"summary":"Remote attackers can enumerate valid users via the web service, exposing user accounts in MB connect line and Helmholz industrial IoT products.","url":"https://insights.sbomify.com/CVE-2022-22520/"}
