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-2019-6527 in the wild and no public exploit code.\n\nAffected product: ICS-CERT PR100088 Modbus gateway. 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-2019-6527/ (Markdown: https://insights.sbomify.com/CVE-2019-6527/index.md)","id":"CVE-2019-6527","markdown":"https://insights.sbomify.com/CVE-2019-6527/index.md","name":"CVE-2019-6527","record":{"aliases":["GHSA-xmgj-jp3c-9mp3"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Modbus gateway","requires_auth":"none","summary":"An attacker can change the admin password of a logged-in user on the Modbus gateway, leading to unauthorized administrative access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"pr100088_modbus_gateway_firmware","vendor":"kunbus"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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"}],"description":"PR100088 Modbus gateway versions prior to Release R02 (or Software Version 1.1.13166) may allow an attacker to be able to change the password for an admin user who is currently or previously logged in, provided the device has not been restarted.","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 PR100088 Modbus gateway","id":"CVE-2019-6527","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in PSI GridConnect GmbH (formerly known as PSI Nentec GmbH) Telecontrol Gateway and Smart Telecontrol Unit family, IEC104 Security Proxy.","id":"CVE-2019-6528"},"packages":[],"prev":{"headline":"Information disclosure in IKS, EDS","id":"CVE-2019-6526"},"products":["PR100088 Modbus gateway"],"published":"2019-02-12","related":[{"cvss_score":9.1,"headline":"Missing authorization in PR100088 Modbus gateway","id":"CVE-2019-6533","kev_date_added":null,"published":"2019-02-12"},{"cvss_score":8.1,"headline":"Information disclosure in PR100088 Modbus gateway","id":"CVE-2019-6531","kev_date_added":null,"published":"2019-04-02"},{"cvss_score":7.2,"headline":"Information disclosure in PR100088 Modbus gateway","id":"CVE-2019-6549","kev_date_added":null,"published":"2019-02-12"},{"cvss_score":4.9,"headline":"Denial of service in PR100088 Modbus gateway","id":"CVE-2019-6529","kev_date_added":null,"published":"2020-01-07"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["ICS-CERT"]},"summary":"An attacker can change the admin password of a logged-in user on the Modbus gateway, leading to unauthorized administrative access.","url":"https://insights.sbomify.com/CVE-2019-6527/"}
