An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-43768 and fix it if it is affected.\n\nWhat it is: CVE-2022-43768 is a high-severity denial of service vulnerability in Siemens SIMATIC CP 1242-7 V2, published on 11 Apr 2023. 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-2022-43768 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC CP 1242-7 V2. 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-2022-43768/ (Markdown: https://insights.sbomify.com/CVE-2022-43768/index.md)","id":"CVE-2022-43768","markdown":"https://insights.sbomify.com/CVE-2022-43768/index.md","name":"CVE-2022-43768","record":{"aliases":["GHSA-wxpj-f564-69x8"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SIMATIC CP","requires_auth":"none","summary":"An attacker can cause a denial of service condition on the webserver of affected Siemens SIMATIC communication processors.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_cp_1242-7_v2_firmware","vendor":"siemens"},{"product":"simatic_cp_1243-1_dnp3_firmware","vendor":"siemens"},{"product":"simatic_cp_1243-1_firmware","vendor":"siemens"},{"product":"simatic_cp_1243-1_iec_firmware","vendor":"siemens"},{"product":"simatic_cp_1243-7_lte_eu_firmware","vendor":"siemens"},{"product":"simatic_cp_1243-7_lte_us_firmware","vendor":"siemens"},{"product":"simatic_cp_1243-8_irc_firmware","vendor":"siemens"},{"product":"simatic_cp_1542sp-1_firmware","vendor":"siemens"},{"product":"simatic_cp_1542sp-1_irc_firmware","vendor":"siemens"},{"product":"simatic_cp_1543sp-1_firmware","vendor":"siemens"},{"product":"simatic_cp_443-1_advanced_firmware","vendor":"siemens"},{"product":"simatic_cp_443-1_firmware","vendor":"siemens"},{"product":"simatic_ipc_diagbase_firmware","vendor":"siemens"},{"product":"simatic_ipc_diagmonitor_firmware","vendor":"siemens"},{"product":"siplus_et_200sp_cp_1542sp-1_irc_tx_rail_firmware","vendor":"siemens"},{"product":"siplus_et_200sp_cp_1543sp-1_isec_firmware","vendor":"siemens"},{"product":"siplus_et_200sp_cp_1543sp-1_isec_tx_rail_firmware","vendor":"siemens"},{"product":"siplus_net_cp_1242-7_v2_firmware","vendor":"siemens"},{"product":"siplus_net_cp_443-1_advanced_firmware","vendor":"siemens"},{"product":"siplus_net_cp_443-1_firmware","vendor":"siemens"},{"product":"siplus_s7-1200_cp_1243-1_firmware","vendor":"siemens"},{"product":"siplus_s7-1200_cp_1243-1_rail_firmware","vendor":"siemens"},{"product":"siplus_tim_1531_irc_firmware","vendor":"siemens"},{"product":"tim_1531_irc_firmware","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A vulnerability has been identified in SIMATIC CP 1242-7 V2 (6GK7242-7KX31-0XE0) (All versions \u003c V3.4.29), SIMATIC CP 1243-1 (6GK7243-1BX30-0XE0) (All versions \u003c V3.4.29), SIMATIC CP 1243-1 DNP3 (incl.
