An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2017-16740 and fix it if it is affected.\n\nWhat it is: CVE-2017-16740 is a critical memory corruption vulnerability in Rockwell Automation Allen-Bradley MicroLogix 1400 Controllers, published on 9 Jan 2018. 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-2017-16740 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation Allen-Bradley MicroLogix 1400 Controllers. 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-2017-16740/ (Markdown: https://insights.sbomify.com/CVE-2017-16740/index.md)","id":"CVE-2017-16740","markdown":"https://insights.sbomify.com/CVE-2017-16740/index.md","name":"CVE-2017-16740","record":{"aliases":["GHSA-f8m9-fwqj-74hf"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PLC controller","requires_auth":"none","summary":"A stack-based buffer overflow in Rockwell Automation MicroLogix 1400 controllers allows remote attackers to execute arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"1766-l32awa_firmware","vendor":"rockwellautomation"},{"product":"1766-l32awaa_firmware","vendor":"rockwellautomation"},{"product":"1766-l32bwa_firmware","vendor":"rockwellautomation"},{"product":"1766-l32bwaa_firmware","vendor":"rockwellautomation"},{"product":"1766-l32bxb_firmware","vendor":"rockwellautomation"},{"product":"1766-l32bxba_firmware","vendor":"rockwellautomation"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A Buffer Overflow issue was discovered in Rockwell Automation Allen-Bradley MicroLogix 1400 Controllers, Series B and C Versions 21.002 and earlier.
