Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-12527 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-2020-12527/ (Markdown: https://insights.sbomify.com/CVE-2020-12527/index.md)","id":"CVE-2020-12527","markdown":"https://insights.sbomify.com/CVE-2020-12527/index.md","name":"CVE-2020-12527","record":{"aliases":["GHSA-vv92-932q-3jmg"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial IoT devices","requires_auth":"low_privilege","summary":"Logged-in users can shut down or reboot devices without proper permissions, causing denial of service in MB connect line and Helmholz products.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"An issue was discovered in MB connect line mymbCONNECT24, mbCONNECT24 and Helmholz myREX24 and myREX24.virtual in all versions through v2.11.2.
