It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-22744 in the wild and no public exploit code.\n\nAffected product: Triconex Model 3009 MP installed on Tricon V11.3.x systems. 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-2021-22744/ (Markdown: https://insights.sbomify.com/CVE-2021-22744/index.md)","id":"CVE-2021-22744","markdown":"https://insights.sbomify.com/CVE-2021-22744/index.md","name":"CVE-2021-22744","record":{"aliases":["GHSA-p3vv-3hv7-rgx3"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Triconex safety controller","requires_auth":"high_privilege","summary":"Malformed packets can reset the Triconex module when the write-protect keyswitch is in program mode, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"tcm_4351b_firmware","vendor":"schneider-electric"},{"product":"triconex_model_3009_mp_firmware","vendor":"schneider-electric"}],"cvss":{"score":3.9,"severity":"low","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"Improper Check for Unusual or Exceptional Conditions vulnerability exists in Triconex Model 3009 MP installed on Tricon V11.3.x systems that could cause module reset when TCM receives malformed TriStation packets while the write-protect keyswitch is in the program position.
