CONPROSYS HMI System (CHS), published on 20 Jan 2023. An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-22339 and fix it if it is affected.\n\nWhat it is: CVE-2023-22339 is a high-severity missing authorization vulnerability in Contec Co., Ltd. CONPROSYS HMI System (CHS), published on 20 Jan 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-2023-22339 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-2023-22339/ (Markdown: https://insights.sbomify.com/CVE-2023-22339/index.md)","id":"CVE-2023-22339","markdown":"https://insights.sbomify.com/CVE-2023-22339/index.md","name":"CVE-2023-22339","record":{"aliases":["GHSA-r659-h3gg-4vrp"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"HMI system","requires_auth":"none","summary":"Remote unauthenticated attackers can bypass access controls to steal server certificates and private keys from CONPROSYS HMI systems.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"conprosys_hmi_system","vendor":"contec"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Improper access control vulnerability in CONPROSYS HMI System (CHS) Ver.3.4.5 and earlier allows a remote unauthenticated attacker to bypass access restriction and obtain the server certificate including the private key of the product.","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":"Missing authorization in CONPROSYS HMI System (CHS)","id":"CVE-2023-22339","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"BIG-IP SIP profile vulnerability","id":"CVE-2023-22340"},"packages":[],"prev":{"headline":"Information disclosure in Intel(R) oneVPL GPU software","id":"CVE-2023-22338"},"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":7.2,"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 unauthenticated attackers can bypass access controls to steal server certificates and private keys from CONPROSYS HMI systems.","url":"https://insights.sbomify.com/CVE-2023-22339/"}
