Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-43439 in the wild and no public exploit code.\n\nAffected product: Siemens POWER METER SICAM Q100. 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-2022-43439/ (Markdown: https://insights.sbomify.com/CVE-2022-43439/index.md)","id":"CVE-2022-43439","markdown":"https://insights.sbomify.com/CVE-2022-43439/index.md","name":"CVE-2022-43439","record":{"aliases":["GHSA-hj8w-fgm6-wx7w"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens power meters","requires_auth":"low_privilege","summary":"Improper input validation in Siemens SICAM power meters allows attackers to cause unexpected behavior or denial of service.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"7kg9501-0aa01-2aa1_firmware","vendor":"siemens"},{"product":"7kg9501-0aa31-2aa1_firmware","vendor":"siemens"}],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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 POWER METER SICAM Q100 (7KG9501-0AA01-0AA1) (All versions \u003c V2.50), POWER METER SICAM Q100 (7KG9501-0AA01-2AA1) (All versions \u003c V2.50), POWER METER SICAM Q100 (7KG9501-0AA31-0AA1) (All versions \u003c V2.50), POWER METER SICAM Q100 (7KG9501-0AA31-2AA1) (All versions \u003c V2.50), SICAM P850 (7KG8500-0AA00-0AA0) (All versions \u003c V3.10), SICAM P850 (7KG8500-0AA00-2AA0) (All versions \u003c V3.10), SICAM P850 (7KG8500-0AA10-0AA0) (All versions \u003c V3.10), SICAM P850 (7KG8500-0AA10-2AA0) (All versions \u003c V3.10), SICAM P850 (7KG8500-0AA30-0AA0) (All versions \u003c V3.10), SICAM P850 (7KG8500-0AA30-2AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA01-0AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA01-2AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA02-0AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA02-2AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA11-0AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA11-2AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA12-0AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA12-2AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA31-0AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA31-2AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA32-0AA0) (All versions \u003c V3.10), SICAM P850 (7KG8501-0AA32-2AA0) (All versions \u003c V3.10), SICAM P855 (7KG8550-0AA00-0AA0) (All versions \u003c V3.10), SICAM P855 (7KG8550-0AA00-2AA0) (All versions \u003c V3.10), SICAM P855 (7KG8550-0AA10-0AA0) (All versions \u003c V3.10), SICAM P855 (7KG8550-0AA10-2AA0) (All versions \u003c V3.10), SICAM P855 (7KG8550-0AA30-0AA0) (All versions \u003c V3.10), SICAM P855 (7KG8550-0AA30-2AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA01-0AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA01-2AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA02-0AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA02-2AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA11-0AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA11-2AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA12-0AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA12-2AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA31-0AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA31-2AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA32-0AA0) (All versions \u003c V3.10), SICAM P855 (7KG8551-0AA32-2AA0) (All versions \u003c V3.10), SICAM T (All versions \u003c V3.0).
