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-2018-4832 in the wild and no public exploit code.\n\nAffected product: Siemens OpenPCS 7 V7.1 and earlier. 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-2018-4832/ (Markdown: https://insights.sbomify.com/CVE-2018-4832/index.md)","id":"CVE-2018-4832","markdown":"https://insights.sbomify.com/CVE-2018-4832/index.md","name":"CVE-2018-4832","record":{"aliases":["GHSA-gx8w-56ch-h8w4"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SIMATIC PCS 7","requires_auth":"none","summary":"Remote attackers can cause denial of service in Siemens SIMATIC products by sending crafted RPC messages, requiring a system reboot to recover.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"openpcs_7","vendor":"siemens"},{"product":"simatic_batch","vendor":"siemens"},{"product":"simatic_net_pc","vendor":"siemens"},{"product":"simatic_net_pc_software","vendor":"siemens"},{"product":"simatic_pcs_7","vendor":"siemens"},{"product":"simatic_route_control","vendor":"siemens"},{"product":"simatic_wincc","vendor":"siemens"},{"product":"simatic_wincc_runtime_professional","vendor":"siemens"},{"product":"sppa-t3000_application_server","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability has been identified in OpenPCS 7 V7.1 and earlier (All versions), OpenPCS 7 V8.0 (All versions), OpenPCS 7 V8.1 (All versions \u003c V8.1 Upd5), OpenPCS 7 V8.2 (All versions), OpenPCS 7 V9.0 (All versions \u003c V9.0 Upd1), SIMATIC BATCH V7.1 and earlier (All versions), SIMATIC BATCH V8.0 (All versions \u003c V8.0 SP1 Upd21), SIMATIC BATCH V8.1 (All versions \u003c V8.1 SP1 Upd16), SIMATIC BATCH V8.2 (All versions \u003c V8.2 Upd10), SIMATIC BATCH V9.0 (All versions \u003c V9.0 SP1), SIMATIC NET PC Software V14 (All versions \u003c V14 SP1 Update 14), SIMATIC NET PC Software V15 (All versions \u003c 15 SP1), SIMATIC PCS 7 V7.1 and earlier (All versions), SIMATIC PCS 7 V8.0 (All versions), SIMATIC PCS 7 V8.1 (All versions), SIMATIC PCS 7 V8.2 (All versions \u003c V8.2 SP1), SIMATIC PCS 7 V9.0 (All versions \u003c V9.0 SP1), SIMATIC Route Control V7.1 and earlier (All versions), SIMATIC Route Control V8.0 (All versions), SIMATIC Route Control V8.1 (All versions), SIMATIC Route Control V8.2 (All versions), SIMATIC Route Control V9.0 (All versions \u003c V9.0 Upd1), SIMATIC WinCC Runtime Professional V13 (All versions \u003c V13 SP2 Upd2), SIMATIC WinCC Runtime Professional V14 (All versions \u003c V14 SP1 Upd5), SIMATIC WinCC V7.2 and earlier (All versions \u003c WinCC 7.2 Upd 15), SIMATIC WinCC V7.3 (All versions \u003c WinCC 7.3 Upd 16), SIMATIC WinCC V7.4 (All versions \u003c V7.4 SP1 Upd 4), SPPA-T3000 Application Server (All versions \u003c Service Pack R8.2 SP2).
