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-2023-1618 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Corporation MELSEC WS Series WS0-GETH00200. 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-2023-1618/ (Markdown: https://insights.sbomify.com/CVE-2023-1618/index.md)","id":"CVE-2023-1618","markdown":"https://insights.sbomify.com/CVE-2023-1618/index.md","name":"CVE-2023-1618","record":{"aliases":["GHSA-37vx-v53j-77pr"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","data_modify","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi Ethernet module","requires_auth":"none","summary":"Remote attackers can bypass authentication via hidden telnet to reset, tamper with, or rewrite firmware on Mitsubishi MELSEC WS modules.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[{"product":"melsec_ws0-geth00200_firmware","vendor":"mitsubishielectric"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"},{"id":"CWE-489","name":"Active Debug Code"}],"description":"Active Debug Code vulnerability in Mitsubishi Electric Corporation MELSEC WS Series WS0-GETH00200 Serial number 2310 **** and prior allows a remote unauthenticated attacker to bypass authentication and illegally log into the affected module by connecting to it via telnet which is hidden function and is enabled by default when shipped from the factory.
