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-2023-22357 in the wild and no public exploit code.\n\nAffected product: OMRON Corporation CP1L-EL20DR-D. 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-2023-22357/ (Markdown: https://insights.sbomify.com/CVE-2023-22357/index.md)","id":"CVE-2023-22357","markdown":"https://insights.sbomify.com/CVE-2023-22357/index.md","name":"CVE-2023-22357","record":{"aliases":["GHSA-rjg6-q2fh-x6mj"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OMRON PLC","requires_auth":"none","summary":"Remote attackers can execute arbitrary commands and read/write memory on OMRON CP1L PLCs due to active debug code, leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"cp1l-el20dr-d_firmware","vendor":"omron"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-489","name":"Active Debug Code"}],"description":"Active debug code exists in OMRON CP1L-EL20DR-D all versions, which may lead to a command that is not specified in FINS protocol being executed without authentication.
