An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-45790 and fix it if it is affected.\n\nWhat it is: CVE-2022-45790 is a high-severity authentication bypass vulnerability in Omron CJ-series and CS-series CPU modules, published on 22 Jan 2024. 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-2022-45790 in the wild and no public exploit code.\n\nAffected product: Omron CJ-series and CS-series CPU modules. 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-2022-45790/ (Markdown: https://insights.sbomify.com/CVE-2022-45790/index.md)","id":"CVE-2022-45790","markdown":"https://insights.sbomify.com/CVE-2022-45790/index.md","name":"CVE-2022-45790","record":{"aliases":["GHSA-c7q6-prxw-fgx7"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Omron PLC CPU","requires_auth":"none","summary":"Attackers can brute-force Omron FINS authentication to access protected memory and overwrite programmed logic in CJ and CS series PLCs.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Dragos","cpe":[{"product":"cj1g-cpu42p_firmware","vendor":"omron"},{"product":"cj1g-cpu43p_firmware","vendor":"omron"},{"product":"cj1g-cpu44p_firmware","vendor":"omron"},{"product":"cj1g-cpu45p-gtc_firmware","vendor":"omron"},{"product":"cj1g-cpu45p_firmware","vendor":"omron"},{"product":"cj2h-cpu64-eip_firmware","vendor":"omron"},{"product":"cj2h-cpu64_firmware","vendor":"omron"},{"product":"cj2h-cpu65-eip_firmware","vendor":"omron"},{"product":"cj2h-cpu65_firmware","vendor":"omron"},{"product":"cj2h-cpu66-eip_firmware","vendor":"omron"},{"product":"cj2h-cpu66_firmware","vendor":"omron"},{"product":"cj2h-cpu67-eip_firmware","vendor":"omron"},{"product":"cj2h-cpu67_firmware","vendor":"omron"},{"product":"cj2h-cpu68-eip_firmware","vendor":"omron"},{"product":"cj2h-cpu68_firmware","vendor":"omron"},{"product":"cj2m-cpu11_firmware","vendor":"omron"},{"product":"cj2m-cpu12_firmware","vendor":"omron"},{"product":"cj2m-cpu13_firmware","vendor":"omron"},{"product":"cj2m-cpu14_firmware","vendor":"omron"},{"product":"cj2m-cpu15_firmware","vendor":"omron"},{"product":"cj2m-cpu31_firmware","vendor":"omron"},{"product":"cj2m-cpu32_firmware","vendor":"omron"},{"product":"cj2m-cpu33_firmware","vendor":"omron"},{"product":"cj2m-cpu34_firmware","vendor":"omron"},{"product":"cj2m-cpu35_firmware","vendor":"omron"},{"product":"cj2m-md211_firmware","vendor":"omron"},{"product":"cj2m-md212_firmware","vendor":"omron"},{"product":"cp1e-e_firmware","vendor":"omron"},{"product":"cp1e-n_firmware","vendor":"omron"},{"product":"cs1d-cpu42s_firmware","vendor":"omron"},{"product":"cs1d-cpu44s_firmware","vendor":"omron"},{"product":"cs1d-cpu65h_firmware","vendor":"omron"},{"product":"cs1d-cpu65p_firmware","vendor":"omron"},{"product":"cs1d-cpu65s_firmware","vendor":"omron"},{"product":"cs1d-cpu67h_firmware","vendor":"omron"},{"product":"cs1d-cpu67p_firmware","vendor":"omron"},{"product":"cs1d-cpu67s_firmware","vendor":"omron"},{"product":"cs1g-cpu42h_firmware","vendor":"omron"},{"product":"cs1g-cpu43h_firmware","vendor":"omron"},{"product":"cs1g-cpu44h_firmware","vendor":"omron"},{"product":"cs1g-cpu45h_firmware","vendor":"omron"},{"product":"cs1h-cpu63h_firmware","vendor":"omron"},{"product":"cs1h-cpu64h_firmware","vendor":"omron"},{"product":"cs1h-cpu65h_firmware","vendor":"omron"},{"product":"cs1h-cpu66h_firmware","vendor":"omron"},{"product":"cs1h-cpu67h_firmware","vendor":"omron"}],"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:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"The Omron FINS protocol has an authenticated feature to prevent access to memory regions.
