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-2025-40570 in the wild and no public exploit code.\n\nAffected product: Siemens SIPROTEC 5 6MD84 (CP300). 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-2025-40570/ (Markdown: https://insights.sbomify.com/CVE-2025-40570/index.md)","id":"CVE-2025-40570","markdown":"https://insights.sbomify.com/CVE-2025-40570/index.md","name":"CVE-2025-40570","record":{"aliases":["GHSA-54cv-chrv-x9h9"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens SIPROTEC 5","requires_auth":"none","summary":"Attackers can cause a denial of service in Siemens SIPROTEC 5 devices by exploiting a resource exhaustion vulnerability, requiring firmware upgrades to mitigate.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":2.4,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A vulnerability has been identified in SIPROTEC 5 6MD84 (CP300) (All versions \u003c V10.0), SIPROTEC 5 6MD85 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 6MD86 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 6MD89 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 6MU85 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7KE85 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7SA82 (CP150) (All versions \u003c V10.0), SIPROTEC 5 7SA86 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7SA87 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7SD82 (CP150) (All versions \u003c V10.0), SIPROTEC 5 7SD86 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7SD87 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7SJ81 (CP150) (All versions \u003c V10.0), SIPROTEC 5 7SJ82 (CP150) (All versions \u003c V10.0), SIPROTEC 5 7SJ85 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7SJ86 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7SK82 (CP150) (All versions \u003c V10.0), SIPROTEC 5 7SK85 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7SL82 (CP150) (All versions \u003c V10.0), SIPROTEC 5 7SL86 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7SL87 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7SS85 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7ST85 (CP300) (All versions \u003c V10.0), SIPROTEC 5 7ST86 (CP300) (All versions \u003c V10.0), SIPROTEC 5 7SX82 (CP150) (All versions \u003c V10.0), SIPROTEC 5 7SX85 (CP300) (All versions \u003c V10.0), SIPROTEC 5 7SY82 (CP150) (All versions \u003c V10.0), SIPROTEC 5 7UM85 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7UT82 (CP150) (All versions \u003c V10.0), SIPROTEC 5 7UT85 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7UT86 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7UT87 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7VE85 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7VK87 (CP300) (All versions \u003e= V7.80 \u003c V10.0), SIPROTEC 5 7VU85 (CP300) (All versions \u003c V10.0), SIPROTEC 5 Compact 7SX800 (CP050) (All versions \u003c V10.0). Affected devices do not properly limit the bandwidth for incoming network packets over their local USB port. This could allow an attacker with physical access to send specially crafted packets with high bandwidth to the affected devices thus forcing them to exhaust their memory and stop responding to any network traffic via the local USB port. Affected devices reset themselves automatically after a successful attack. The protection function is not affected of this vulnerability.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in SIPROTEC 5 6MD84 (CP300)","id":"CVE-2025-40570","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Mendix OIDC SSO (Mendix 10.12 compatible)","id":"CVE-2025-40571"},"packages":[],"prev":{"headline":"Race condition in RUGGEDCOM RST2428P","id":"CVE-2025-40569"},"products":["SIPROTEC 5 6MD84 (CP300)","SIPROTEC 5 6MD85 (CP300)","SIPROTEC 5 6MD86 (CP300)","SIPROTEC 5 6MD89 (CP300)","SIPROTEC 5 6MU85 (CP300)","SIPROTEC 5 7KE85 (CP300)","SIPROTEC 5 7SA82 (CP150)","SIPROTEC 5 7SA86 (CP300)","SIPROTEC 5 7SA87 (CP300)","SIPROTEC 5 7SD82 (CP150)","SIPROTEC 5 7SD86 (CP300)","SIPROTEC 5 7SD87 (CP300)","SIPROTEC 5 7SJ81 (CP150)","SIPROTEC 5 7SJ82 (CP150)","SIPROTEC 5 7SJ85 (CP300)","SIPROTEC 5 7SJ86 (CP300)","SIPROTEC 5 7SK82 (CP150)","SIPROTEC 5 7SK85 (CP300)","SIPROTEC 5 7SL82 (CP150)","SIPROTEC 5 7SL86 (CP300)","SIPROTEC 5 7SL87 (CP300)","SIPROTEC 5 7SS85 (CP300)","SIPROTEC 5 7ST85 (CP300)","SIPROTEC 5 7ST86 (CP300)","SIPROTEC 5 7SX82 (CP150)","SIPROTEC 5 7SX85 (CP300)","SIPROTEC 5 7SY82 (CP150)","SIPROTEC 5 7UM85 (CP300)","SIPROTEC 5 7UT82 (CP150)","SIPROTEC 5 7UT85 (CP300)","SIPROTEC 5 7UT86 (CP300)","SIPROTEC 5 7UT87 (CP300)","SIPROTEC 5 7VE85 (CP300)","SIPROTEC 5 7VK87 (CP300)","SIPROTEC 5 7VU85 (CP300)","SIPROTEC 5 Compact 7SX800 (CP050)"],"published":"2025-08-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-08-12","vendors":["Siemens"]},"summary":"Attackers can cause a denial of service in Siemens SIPROTEC 5 devices by exploiting a resource exhaustion vulnerability, requiring firmware upgrades to mitigate.","url":"https://insights.sbomify.com/CVE-2025-40570/"}
