Screen Creator Advance2, HMI GC-A2 series, and Real time remote monitoring and control tool, published on 18 May 2022. 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-2022-29518 in the wild and no public exploit code.\n\nAffected product: KOYO ELECTRONICS INDUSTRIES CO., LTD. Screen Creator Advance2, HMI GC-A2 series, and Real time remote monitoring and control tool. 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-2022-29518/ (Markdown: https://insights.sbomify.com/CVE-2022-29518/index.md)","id":"CVE-2022-29518","markdown":"https://insights.sbomify.com/CVE-2022-29518/index.md","name":"CVE-2022-29518","record":{"aliases":["GHSA-8865-jmrq-w257"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read","data_modify","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HMI and monitoring tool","requires_auth":"low_privilege","summary":"Local attackers can bypass authentication in Koyo Electronics HMI tools to read, modify, or delete data and illegally operate connected equipment.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"gc-a22w-cw_firmware","vendor":"koyoele"},{"product":"gc-a24-m_firmware","vendor":"koyoele"},{"product":"gc-a24_firmware","vendor":"koyoele"},{"product":"gc-a24w-c\\(w\\)_firmware","vendor":"koyoele"},{"product":"gc-a25_firmware","vendor":"koyoele"},{"product":"gc-a26-j2_firmware","vendor":"koyoele"},{"product":"gc-a26_firmware","vendor":"koyoele"},{"product":"gc-a26w-c\\(w\\)_firmware","vendor":"koyoele"},{"product":"remote_gc","vendor":"koyoele"},{"product":"screen_creator_advance_2","vendor":"koyoele"}],"cvss":{"score":7,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"Screen Creator Advance2, HMI GC-A2 series, and Real time remote monitoring and control tool Screen Creator Advance2 versions prior to Ver.0.1.1.3 Build01, HMI GC-A2 series(GC-A22W-CW, GC-A24W-C(W), GC-A26W-C(W), GC-A24, GC-A24-M, GC-A25, GC-A26, and GC-A26-J2), and Real time remote monitoring and control tool(Remote GC) allows a local attacker to bypass authentication due to the improper check for the Remote control setting's account names.
