An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-31766 and fix it if it is affected.\n\nWhat it is: CVE-2022-31766 is a high-severity vulnerability in Siemens RUGGEDCOM RM1224 LTE(4G) EU, published on 11 Oct 2022. 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-2022-31766 in the wild and no public exploit code.\n\nAffected product: Siemens RUGGEDCOM RM1224 LTE(4G) EU. 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-2022-31766/ (Markdown: https://insights.sbomify.com/CVE-2022-31766/index.md)","id":"CVE-2022-31766","markdown":"https://insights.sbomify.com/CVE-2022-31766/index.md","name":"CVE-2022-31766","record":{"aliases":["GHSA-gh7w-58g5-rmwx"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SCALANCE router","requires_auth":"none","summary":"An improper input validation vulnerability in Siemens SCALANCE routers allows attackers to cause a denial of service.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"ruggedcom_rm1224_firmware","vendor":"siemens"},{"product":"scalance_m804pb_firmware","vendor":"siemens"},{"product":"scalance_m812-1_firmware","vendor":"siemens"},{"product":"scalance_m816-1_firmware","vendor":"siemens"},{"product":"scalance_m826-2_firmware","vendor":"siemens"},{"product":"scalance_m874-2_firmware","vendor":"siemens"},{"product":"scalance_m874-3_firmware","vendor":"siemens"},{"product":"scalance_m876-3_firmware","vendor":"siemens"},{"product":"scalance_m876-4_firmware","vendor":"siemens"},{"product":"scalance_mum853-1_firmware","vendor":"siemens"},{"product":"scalance_mum856-1_firmware","vendor":"siemens"},{"product":"scalance_s615_firmware","vendor":"siemens"},{"product":"scalance_wam763-1_firmware","vendor":"siemens"},{"product":"scalance_wam766-1_firmware","vendor":"siemens"},{"product":"scalance_wum763-1_firmware","vendor":"siemens"},{"product":"scalance_wum766-1_firmware","vendor":"siemens"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/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 RUGGEDCOM RM1224 LTE(4G) EU (6GK6108-4AM00-2BA2) (All versions \u003c V7.1.2), RUGGEDCOM RM1224 LTE(4G) NAM (6GK6108-4AM00-2DA2) (All versions \u003c V7.1.2), SCALANCE M804PB (6GK5804-0AP00-2AA2) (All versions \u003c V7.1.2), SCALANCE M812-1 ADSL-Router (6GK5812-1AA00-2AA2) (All versions \u003c V7.1.2), SCALANCE M812-1 ADSL-Router (6GK5812-1BA00-2AA2) (All versions \u003c V7.1.2), SCALANCE M816-1 ADSL-Router (6GK5816-1AA00-2AA2) (All versions \u003c V7.1.2), SCALANCE M816-1 ADSL-Router (6GK5816-1BA00-2AA2) (All versions \u003c V7.1.2), SCALANCE M826-2 SHDSL-Router (6GK5826-2AB00-2AB2) (All versions \u003c V7.1.2), SCALANCE M874-2 (6GK5874-2AA00-2AA2) (All versions \u003c V7.1.2), SCALANCE M874-3 (6GK5874-3AA00-2AA2) (All versions \u003c V7.1.2), SCALANCE M876-3 (6GK5876-3AA02-2BA2) (All versions \u003c V7.1.2), SCALANCE M876-3 (ROK) (6GK5876-3AA02-2EA2) (All versions \u003c V7.1.2), SCALANCE M876-4 (6GK5876-4AA10-2BA2) (All versions \u003c V7.1.2), SCALANCE M876-4 (EU) (6GK5876-4AA00-2BA2) (All versions \u003c V7.1.2), SCALANCE M876-4 (NAM) (6GK5876-4AA00-2DA2) (All versions \u003c V7.1.2), SCALANCE MUM853-1 (EU) (6GK5853-2EA00-2DA1) (All versions \u003c V7.1.2), SCALANCE MUM856-1 (EU) (6GK5856-2EA00-3DA1) (All versions \u003c V7.1.2), SCALANCE MUM856-1 (RoW) (6GK5856-2EA00-3AA1) (All versions \u003c V7.1.2), SCALANCE S615 EEC LAN-Router (6GK5615-0AA01-2AA2) (All versions \u003c V7.1.2), SCALANCE S615 LAN-Router (6GK5615-0AA00-2AA2) (All versions \u003c V7.1.2), SCALANCE WAM763-1 (6GK5763-1AL00-7DA0) (All versions \u003e= V1.1.0 \u003c V3.0.0), SCALANCE WAM766-1 (6GK5766-1GE00-7DA0) (All versions \u003e= V1.1.0 \u003c V3.0.0), SCALANCE WAM766-1 (US) (6GK5766-1GE00-7DB0) (All versions \u003e= V1.1.0 \u003c V3.0.0), SCALANCE WAM766-1 EEC (6GK5766-1GE00-7TA0) (All versions \u003e= V1.1.0 \u003c V3.0.0), SCALANCE WAM766-1 EEC (US) (6GK5766-1GE00-7TB0) (All versions \u003e= V1.1.0 \u003c V3.0.0), SCALANCE WUM763-1 (6GK5763-1AL00-3AA0) (All versions \u003e= V1.1.0 \u003c V3.0.0), SCALANCE WUM763-1 (6GK5763-1AL00-3DA0) (All versions \u003e= V1.1.0 \u003c V3.0.0), SCALANCE WUM766-1 (6GK5766-1GE00-3DA0) (All versions \u003e= V1.1.0 \u003c V3.0.0), SCALANCE WUM766-1 (USA) (6GK5766-1GE00-3DB0) (All versions \u003e= V1.1.0 \u003c V3.0.0).
