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-2021-32984 in the wild and no public exploit code.\n\nAffected product: Automation Direct CLICK PLC CPU Modules: C0-1x CPUs. 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-2021-32984/ (Markdown: https://insights.sbomify.com/CVE-2021-32984/index.md)","id":"CVE-2021-32984","markdown":"https://insights.sbomify.com/CVE-2021-32984/index.md","name":"CVE-2021-32984","record":{"aliases":["GHSA-w93w-26gf-h3c5"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"PLC CPU Module","requires_auth":"none","summary":"Attackers can bypass authentication to read PLC projects when the device is unlocked by an authorized user, requiring firmware updates to mitigate.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"c0-10are-d_firmware","vendor":"automationdirect"},{"product":"c0-10dd1e-d_firmware","vendor":"automationdirect"},{"product":"c0-10dd2e-d_firmware","vendor":"automationdirect"},{"product":"c0-10dre-d_firmware","vendor":"automationdirect"},{"product":"c0-11are-d_firmware","vendor":"automationdirect"},{"product":"c0-11dd1e-d_firmware","vendor":"automationdirect"},{"product":"c0-11dd2e-d_firmware","vendor":"automationdirect"},{"product":"c0-11dre-d_firmware","vendor":"automationdirect"},{"product":"c0-12are-1-d_firmware","vendor":"automationdirect"},{"product":"c0-12are-2-d_firmware","vendor":"automationdirect"},{"product":"c0-12are-d_firmware","vendor":"automationdirect"},{"product":"c0-12dd1e-1-d_firmware","vendor":"automationdirect"},{"product":"c0-12dd1e-2-d_firmware","vendor":"automationdirect"},{"product":"c0-12dd1e-d_firmware","vendor":"automationdirect"},{"product":"c0-12dd2e-1-d_firmware","vendor":"automationdirect"},{"product":"c0-12dd2e-2-d_firmware","vendor":"automationdirect"},{"product":"c0-12dd2e-d_firmware","vendor":"automationdirect"},{"product":"c0-12dre-1-d_firmware","vendor":"automationdirect"},{"product":"c0-12dre-2-d_firmware","vendor":"automationdirect"},{"product":"c0-12dre-d_firmware","vendor":"automationdirect"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-287","name":"Improper Authentication"},{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"All programming connections receive the same unlocked privileges, which can result in a privilege escalation.
