It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-11453 in the wild and no public exploit code.\n\nAffected product: Siemens AG SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V10, V11, V12, SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V13, SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V14, SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V15. 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-2018-11453/ (Markdown: https://insights.sbomify.com/CVE-2018-11453/index.md)","id":"CVE-2018-11453","markdown":"https://insights.sbomify.com/CVE-2018-11453/index.md","name":"CVE-2018-11453","record":{"aliases":["GHSA-rg7v-v5mq-rpj8"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens TIA Portal","requires_auth":"low_privilege","summary":"Local attackers can exploit improper file permissions to insert malicious files, causing denial of service or code execution in Siemens TIA Portal.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_step_7_\\(tia_portal\\)","vendor":"siemens"},{"product":"simatic_wincc_\\(tia_portal\\)","vendor":"siemens"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"A vulnerability has been identified in SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V10, V11, V12 (All versions), SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V13 (All versions \u003c V13 SP2 Update 2), SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V14 (All versions \u003c V14 SP1 Update 6), SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V15 (All versions \u003c V15 Update 2).
