An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-30937 and fix it if it is affected.\n\nWhat it is: CVE-2022-30937 is a high-severity memory corruption vulnerability in Siemens EN100 Ethernet module DNP3 IP variant, published on 14 Jun 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-2022-30937 in the wild and no public exploit code.\n\nAffected product: Siemens EN100 Ethernet module DNP3 IP variant. 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-2022-30937/ (Markdown: https://insights.sbomify.com/CVE-2022-30937/index.md)","id":"CVE-2022-30937","markdown":"https://insights.sbomify.com/CVE-2022-30937/index.md","name":"CVE-2022-30937","record":{"aliases":["GHSA-963r-c9px-2q9j"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens EN100 Ethernet module","requires_auth":"none","summary":"An attacker can crash the Siemens EN100 Ethernet module by sending specially crafted HTTP packets to the /txtrace endpoint, causing a denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"en100_ethernet_module_dnp3_firmware","vendor":"siemens"},{"product":"en100_ethernet_module_iec_104_firmware","vendor":"siemens"},{"product":"en100_ethernet_module_iec_61850_firmware","vendor":"siemens"},{"product":"en100_ethernet_module_modbus_tcp_firmware","vendor":"siemens"},{"product":"en100_ethernet_module_profinet_io_firmware","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-787","name":"Out-of-bounds Write"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability has been identified in EN100 Ethernet module DNP3 IP variant (All versions), EN100 Ethernet module IEC 104 variant (All versions), EN100 Ethernet module IEC 61850 variant (All versions \u003c V4.37), EN100 Ethernet module Modbus TCP variant (All versions), EN100 Ethernet module PROFINET IO variant (All versions).
