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-2018-7804 in the wild and no public exploit code.\n\nAffected product: Schneider Electric SE Embedded Web Servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200. 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-2018-7804/ (Markdown: https://insights.sbomify.com/CVE-2018-7804/index.md)","id":"CVE-2018-7804","markdown":"https://insights.sbomify.com/CVE-2018-7804/index.md","name":"CVE-2018-7804","record":{"aliases":["GHSA-prjw-g7wq-rf93"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Modicon PLC web server","requires_auth":"none","summary":"Attackers can redirect users to malicious sites via crafted links in Schneider Electric Modicon PLC embedded web servers.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"modicom_bmxnor0200h_firmware","vendor":"schneider-electric"},{"product":"modicom_m340_firmware","vendor":"schneider-electric"},{"product":"modicom_premium_firmware","vendor":"schneider-electric"},{"product":"modicom_quantum_firmware","vendor":"schneider-electric"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"A URL Redirection to Untrusted Site vulnerability exists in the embedded web servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200 where a user clicking on a specially crafted link can be redirected to a URL of the attacker's choosing.","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":"Open redirect in Embedded Web Servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200","id":"CVE-2018-7804","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Data Center Operation all versions","id":"CVE-2018-7806"},"packages":[],"prev":{"headline":"Denial of service in Triconex TriStation Emulator V1.2.0","id":"CVE-2018-7803"},"products":["Embedded Web Servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200"],"published":"2018-12-17","related":[{"cvss_score":9.8,"headline":"Auth bypass in Embedded Web Servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200","id":"CVE-2018-7809","kev_date_added":null,"published":"2018-11-30"},{"cvss_score":9.8,"headline":"Auth bypass in Embedded Web Servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200","id":"CVE-2018-7811","kev_date_added":null,"published":"2018-11-30"},{"cvss_score":8.8,"headline":"Cross-site scripting in Embedded Web Servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200","id":"CVE-2018-7831","kev_date_added":null,"published":"2018-11-30"},{"cvss_score":7.5,"headline":"Information disclosure in Embedded Web Servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200","id":"CVE-2018-7812","kev_date_added":null,"published":"2018-12-17"},{"cvss_score":7.5,"headline":"Denial of service in Embedded Web Servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200","id":"CVE-2018-7833","kev_date_added":null,"published":"2018-12-17"},{"cvss_score":7.5,"headline":"Other in Embedded Web Servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200","id":"CVE-2018-7830","kev_date_added":null,"published":"2018-11-30"}],"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":"2024-08-05","vendors":["Schneider Electric SE"]},"summary":"Attackers can redirect users to malicious sites via crafted links in Schneider Electric Modicon PLC embedded web servers.","url":"https://insights.sbomify.com/CVE-2018-7804/"}
