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-2020-28397 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC Drive Controller family. 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-2020-28397/ (Markdown: https://insights.sbomify.com/CVE-2020-28397/index.md)","id":"CVE-2020-28397","markdown":"https://insights.sbomify.com/CVE-2020-28397/index.md","name":"CVE-2020-28397","record":{"aliases":["GHSA-wg3f-fv3w-mw54"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens PLC","requires_auth":"none","summary":"An attacker can extract protected PLC program variables via port 102/tcp due to incorrect authorization checks in Siemens SIMATIC devices.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"cpu1510sp_f-1_firmware","vendor":"siemens"},{"product":"cpu_1211c_firmware","vendor":"siemens"},{"product":"cpu_1212c_firmware","vendor":"siemens"},{"product":"cpu_1212fc_firmware","vendor":"siemens"},{"product":"cpu_1214c_firmware","vendor":"siemens"},{"product":"cpu_1214fc_firmware","vendor":"siemens"},{"product":"cpu_1215c_firmware","vendor":"siemens"},{"product":"cpu_1215fc_firmware","vendor":"siemens"},{"product":"cpu_1217c_firmware","vendor":"siemens"},{"product":"cpu_1504d_tf_firmware","vendor":"siemens"},{"product":"cpu_1507d_tf_firmware","vendor":"siemens"},{"product":"cpu_1510sp-1pn_firmware","vendor":"siemens"},{"product":"cpu_1511-1pn_firmware","vendor":"siemens"},{"product":"cpu_1511c-1_pn_firmware","vendor":"siemens"},{"product":"cpu_1511f-1pn_firmware","vendor":"siemens"},{"product":"cpu_1511t-1pn_firmware","vendor":"siemens"},{"product":"cpu_1511tf-1pn_firmware","vendor":"siemens"},{"product":"cpu_1512c-1_pn_firmware","vendor":"siemens"},{"product":"cpu_1512sp-1_pn_firmware","vendor":"siemens"},{"product":"cpu_1512sp_f-1_pn_firmware","vendor":"siemens"},{"product":"cpu_1513-1_pn_firmware","vendor":"siemens"},{"product":"cpu_1513f-1_pn_firmware","vendor":"siemens"},{"product":"cpu_1513pro_f-2_pn_firmware","vendor":"siemens"},{"product":"cpu_1513r-1_pn_firmware","vendor":"siemens"},{"product":"cpu_1515-2_firmware","vendor":"siemens"},{"product":"cpu_1515f-2_firmware","vendor":"siemens"},{"product":"cpu_1515r-2_pn_firmware","vendor":"siemens"},{"product":"cpu_1515sp_pc2_tf_firmware","vendor":"siemens"},{"product":"cpu_1515t-2_pn_firmware","vendor":"siemens"},{"product":"cpu_1515tf-2_pn_firmware","vendor":"siemens"},{"product":"cpu_1516-3_firmware","vendor":"siemens"},{"product":"cpu_1516f-3_firmware","vendor":"siemens"},{"product":"cpu_1516pro-2_pn_firmware","vendor":"siemens"},{"product":"cpu_1516pro_f-2_pn_firmware","vendor":"siemens"},{"product":"cpu_1516t-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"cpu_1516tf-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"cpu_1517-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"cpu_1517f-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"cpu_1517t-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"cpu_1517tf-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"cpu_1518-4_pn\\/dp_firmware","vendor":"siemens"},{"product":"cpu_1518f-4_pn\\/dp_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_software_controller","vendor":"siemens"},{"product":"simatic_s7_plcsim_advanced_firmware","vendor":"siemens"},{"product":"siplus_cpu-1516f-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"siplus_cpu_1510sp_f-1pn_firmware","vendor":"siemens"},{"product":"siplus_cpu_1511-1_pn_firmware","vendor":"siemens"},{"product":"siplus_cpu_1511f-1_pn_firmware","vendor":"siemens"},{"product":"siplus_cpu_1512sp-1_pn_firmware","vendor":"siemens"},{"product":"siplus_cpu_1512sp_f-1pn_firmware","vendor":"siemens"},{"product":"siplus_cpu_1513-1_pn_firmware","vendor":"siemens"},{"product":"siplus_cpu_1513f-1_pn_firmware","vendor":"siemens"},{"product":"siplus_cpu_1516-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"siplus_cpu_1518-4_pn\\/dp_firmware","vendor":"siemens"},{"product":"siplus_cpu_1518f-4_pn\\/dp_firmware","vendor":"siemens"},{"product":"tim_1531_irc_firmware","vendor":"siemens"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","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-863","name":"Incorrect Authorization"}],"description":"A vulnerability has been identified in SIMATIC Drive Controller family (All versions \u003c V2.9.2), SIMATIC ET 200SP Open Controller CPU 1515SP PC2 (incl.
