An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-34819 and fix it if it is affected.\n\nWhat it is: CVE-2022-34819 is a critical memory corruption vulnerability in Siemens SIMATIC CP 1242-7 V2, published on 12 Jul 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-2022-34819 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-2022-34819/ (Markdown: https://insights.sbomify.com/CVE-2022-34819/index.md)","id":"CVE-2022-34819","markdown":"https://insights.sbomify.com/CVE-2022-34819/index.md","name":"CVE-2022-34819","record":{"aliases":["GHSA-x7cp-9x6c-2mm8"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SIMATIC CP","requires_auth":"none","summary":"Heap-based buffer overflow in Siemens SIMATIC CP devices allows remote attackers to execute arbitrary code via crafted messages.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_cp_1242-7_v2_firmware","vendor":"siemens"},{"product":"simatic_cp_1243-1_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_irc_firmware","vendor":"siemens"},{"product":"simatic_cp_1543-1_firmware","vendor":"siemens"},{"product":"simatic_cp_1543sp-1_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_1543-1_firmware","vendor":"siemens"},{"product":"siplus_s7-1200_cp_1243-1_firmware","vendor":"siemens"},{"product":"siplus_s7-1200_cp_1243-1_rail_firmware","vendor":"siemens"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A vulnerability has been identified in SIMATIC CP 1242-7 V2 (All versions \u003c V3.3.46), SIMATIC CP 1243-1 (All versions \u003c V3.3.46), SIMATIC CP 1243-7 LTE EU (All versions \u003c V3.3.46), SIMATIC CP 1243-7 LTE US (All versions \u003c V3.3.46), SIMATIC CP 1243-8 IRC (All versions \u003c V3.3.46), SIMATIC CP 1542SP-1 IRC (All versions \u003e= V2.0 \u003c V2.2.28), SIMATIC CP 1543-1 (All versions \u003c V3.0.22), SIMATIC CP 1543SP-1 (All versions \u003e= V2.0 \u003c V2.2.28), SIPLUS ET 200SP CP 1542SP-1 IRC TX RAIL (All versions \u003e= V2.0 \u003c V2.2.28), SIPLUS ET 200SP CP 1543SP-1 ISEC (All versions \u003e= V2.0 \u003c V2.2.28), SIPLUS ET 200SP CP 1543SP-1 ISEC TX RAIL (All versions \u003e= V2.0 \u003c V2.2.28), SIPLUS NET CP 1242-7 V2 (All versions \u003c V3.3.46), SIPLUS NET CP 1543-1 (All versions \u003c V3.0.22), SIPLUS S7-1200 CP 1243-1 (All versions \u003c V3.3.46), SIPLUS S7-1200 CP 1243-1 RAIL (All versions \u003c V3.3.46).
