An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-27388 and fix it if it is affected.\n\nWhat it is: CVE-2023-27388 is a critical authentication bypass vulnerability in T\u0026D Corporation and ESPEC MIC CORP. data logger products, published on 23 May 2023. 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-2023-27388 in the wild and no public exploit code.\n\nAffected product: T\u0026D Corporation and ESPEC MIC CORP. data logger products. 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-2023-27388/ (Markdown: https://insights.sbomify.com/CVE-2023-27388/index.md)","id":"CVE-2023-27388","markdown":"https://insights.sbomify.com/CVE-2023-27388/index.md","name":"CVE-2023-27388","record":{"aliases":["GHSA-h3jh-74f5-29gh"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Data logger firmware","requires_auth":"none","summary":"Remote unauthenticated attackers can bypass authentication to log in as registered users on T\u0026D and ESPEC data logger devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"rs-12n_firmware","vendor":"especmic"},{"product":"rt-12n_firmware","vendor":"especmic"},{"product":"rt-22bn_firmware","vendor":"especmic"},{"product":"teu-12n_firmware","vendor":"especmic"},{"product":"rtr-5w_firmware","vendor":"tandd"},{"product":"tr-71w_firmware","vendor":"tandd"},{"product":"tr-72w_firmware","vendor":"tandd"},{"product":"wdr-3_firmware","vendor":"tandd"},{"product":"wdr-7_firmware","vendor":"tandd"},{"product":"ws-2_firmware","vendor":"tandd"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-863","name":"Incorrect Authorization"}],"description":"Improper authentication vulnerability in T\u0026D Corporation and ESPEC MIC CORP. data logger products allows a remote unauthenticated attacker to login to the product as a registered user.
