An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-51438 exists.\n\nAffected product: Siemens SIMATIC IPC1047E. 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-2023-51438/ (Markdown: https://insights.sbomify.com/CVE-2023-51438/index.md)","id":"CVE-2023-51438","markdown":"https://insights.sbomify.com/CVE-2023-51438/index.md","name":"CVE-2023-51438","record":{"aliases":["GHSA-r573-6cpv-hcwq"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Siemens SIMATIC IPC","requires_auth":"none","summary":"Unauthorized access is possible in Siemens SIMATIC IPC devices when the Redfish server is enabled for remote management.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"maxview_storage_manager","vendor":"microchip"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability has been identified in SIMATIC IPC1047E (All versions with maxView Storage Manager \u003c V4.14.00.26068 on Windows), SIMATIC IPC647E (All versions with maxView Storage Manager \u003c V4.14.00.26068 on Windows), SIMATIC IPC847E (All versions with maxView Storage Manager \u003c V4.14.00.26068 on Windows).
