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-2019-5079 in the wild and no public exploit code.\n\nAffected product: WAGO PFC100. 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-2019-5079/ (Markdown: https://insights.sbomify.com/CVE-2019-5079/index.md)","id":"CVE-2019-5079","markdown":"https://insights.sbomify.com/CVE-2019-5079/index.md","name":"CVE-2019-5079","record":{"aliases":["GHSA-69j7-ff29-gmc8"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WAGO PFC controller","requires_auth":"none","summary":"An attacker can send unauthenticated packets to trigger a heap buffer overflow in WAGO PFC controllers, potentially leading to remote code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"pfc_100_firmware","vendor":"wago"},{"product":"pfc_200_firmware","vendor":"wago"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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-787","name":"Out-of-bounds Write"}],"description":"An exploitable heap buffer overflow vulnerability exists in the iocheckd service \"I/O-Check\" functionality of WAGO PFC200 Firmware versions 03.01.07(13) and 03.00.39(12), and WAGO PFC100 Firmware version 03.00.39(12).
