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-2018-11457 in the wild and no public exploit code.\n\nAffected product: Siemens AG SINUMERIK 828D V4.7, SINUMERIK 840D sl V4.7, SINUMERIK 840D sl V4.8. 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-2018-11457/ (Markdown: https://insights.sbomify.com/CVE-2018-11457/index.md)","id":"CVE-2018-11457","markdown":"https://insights.sbomify.com/CVE-2018-11457/index.md","name":"CVE-2018-11457","record":{"aliases":["GHSA-r3r8-fw5q-863c"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"SINUMERIK CNC controller","requires_auth":"none","summary":"Remote attackers can execute privileged code on SINUMERIK CNC controllers via the web server if port 4842 is manually opened in the firewall.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"sinumerik_828d_v4.7_firmware","vendor":"siemens"},{"product":"sinumerik_840d_sl_v4.7_firmware","vendor":"siemens"},{"product":"sinumerik_840d_sl_v4.8_firmware","vendor":"siemens"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A vulnerability has been identified in SINUMERIK 828D V4.7 (All versions \u003c V4.7 SP6 HF1), SINUMERIK 840D sl V4.7 (All versions \u003c V4.7 SP6 HF5), SINUMERIK 840D sl V4.8 (All versions \u003c V4.8 SP3).
