CONPROSYS HMI System (CHS), published on 20 Jan 2023. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-22334 in the wild and no public exploit code.\n\nAffected product: Contec Co., Ltd. CONPROSYS HMI System (CHS). 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-2023-22334/ (Markdown: https://insights.sbomify.com/CVE-2023-22334/index.md)","id":"CVE-2023-22334","markdown":"https://insights.sbomify.com/CVE-2023-22334/index.md","name":"CVE-2023-22334","record":{"aliases":["GHSA-4h9q-9r2g-27j5"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"HMI system","requires_auth":"low_privilege","summary":"Remote attackers can intercept credentials via man-in-the-middle attacks due to improper authentication handling in CONPROSYS HMI systems.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"conprosys_hmi_system","vendor":"contec"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Use of password hash instead of password for authentication vulnerability in CONPROSYS HMI System (CHS) Ver.3.4.5 and earlier allows a remote authenticated attacker to obtain user credentials information via a man-in-the-middle attack.","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":"Auth bypass in CONPROSYS HMI System (CHS)","id":"CVE-2023-22334","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"Missing authorization in SS1 and Rakuraku PC Cloud","id":"CVE-2023-22335"},"packages":[],"prev":{"headline":"Cross-site scripting in EasyMail","id":"CVE-2023-22333"},"products":["CONPROSYS HMI System (CHS)"],"published":"2023-01-20","related":[{"cvss_score":9.8,"headline":"Command injection in CONPROSYS HMI System (CHS)","id":"CVE-2022-44456","kev_date_added":null,"published":"2022-12-19"},{"cvss_score":8.8,"headline":"Privilege escalation in CONPROSYS HMI System (CHS)","id":"CVE-2023-28657","kev_date_added":null,"published":"2023-06-01"},{"cvss_score":8.1,"headline":"Information disclosure in CONPROSYS HMI System (CHS)","id":"CVE-2023-28713","kev_date_added":null,"published":"2023-06-01"},{"cvss_score":7.8,"headline":"Missing authorization in CONPROSYS HMI System (CHS)","id":"CVE-2023-28399","kev_date_added":null,"published":"2023-06-01"},{"cvss_score":7.5,"headline":"Hardcoded credentials in CONPROSYS HMI System (CHS)","id":"CVE-2023-22331","kev_date_added":null,"published":"2023-01-20"},{"cvss_score":7.5,"headline":"Missing authorization in CONPROSYS HMI System (CHS)","id":"CVE-2023-22339","kev_date_added":null,"published":"2023-01-20"},{"cvss_score":7.2,"headline":"SQL injection in CONPROSYS HMI System (CHS)","id":"CVE-2023-29154","kev_date_added":null,"published":"2023-06-01"}],"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":"2025-04-03","vendors":["Contec Co., Ltd."]},"summary":"Remote attackers can intercept credentials via man-in-the-middle attacks due to improper authentication handling in CONPROSYS HMI systems.","url":"https://insights.sbomify.com/CVE-2023-22334/"}
