An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-3373 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Corporation GOT SIMPLE Series GS21 model. 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-2023-3373/ (Markdown: https://insights.sbomify.com/CVE-2023-3373/index.md)","id":"CVE-2023-3373","markdown":"https://insights.sbomify.com/CVE-2023-3373/index.md","name":"CVE-2023-3373","record":{"aliases":["GHSA-5gwv-ww26-4rhf"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["account_takeover","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"HMI industrial controller","requires_auth":"none","summary":"Remote attackers can hijack data sessions or cause denial of service by predicting FTP listening ports on Mitsubishi Electric HMI devices.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[{"product":"gs21_firmware","vendor":"mitsubishielectric"},{"product":"gt21_firmware","vendor":"mitsubishielectric"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"},{"id":"CWE-342","name":"Predictable Exact Value from Previous Values"}],"description":"Predictable Exact Value from Previous Values vulnerability in Mitsubishi Electric Corporation GOT2000 Series GT21 model versions 01.49.000 and prior and GOT SIMPLE Series GS21 model versions 01.49.000 and prior allows a remote unauthenticated attacker to hijack data connections (session hijacking) or prevent legitimate users from establishing data connections (to cause DoS condition) by guessing the listening port of the data connection on FTP server and connecting to it.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Information disclosure in GOT SIMPLE Series GS21 model","id":"CVE-2023-3373","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Privilege Escalation in Bookreen","id":"CVE-2023-3374"},"packages":[],"prev":{"headline":"Lana Shortcodes \u003c 1.2.0 - Contributor+ Stored XSS","id":"CVE-2023-3372"},"products":["GOT SIMPLE Series GS21 model","GOT2000 Series GT21 model"],"published":"2023-08-03","related":[{"cvss_score":7.5,"headline":"Weak cryptography in GOT SIMPLE Series GS21 model","id":"CVE-2023-0525","kev_date_added":null,"published":"2023-08-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-27","vendors":["Mitsubishi Electric Corporation"]},"summary":"Remote attackers can hijack data sessions or cause denial of service by predicting FTP listening ports on Mitsubishi Electric HMI devices.","url":"https://insights.sbomify.com/CVE-2023-3373/"}
