An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-19421 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-19421/ (Markdown: https://insights.sbomify.com/CVE-2018-19421/index.md)","id":"CVE-2018-19421","markdown":"https://insights.sbomify.com/CVE-2018-19421/index.md","name":"CVE-2018-19421","record":{"aliases":["GHSA-6p82-h3ww-f963"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"GetSimple CMS","requires_auth":"high_privilege","summary":"Attackers can upload malicious .eml files to execute code via Internet Explorer rendering, bypassing HTML upload restrictions in GetSimple CMS.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"getsimple_cms","vendor":"get-simple"}],"cvss":{"score":3.8,"severity":"low","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"In GetSimpleCMS 3.3.15, admin/upload.php blocks .html uploads but Internet Explorer render HTML elements in a .eml file, because of admin/upload-uploadify.php, and validate_safe_file in admin/inc/security_functions.php.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"File upload in n/a","id":"CVE-2018-19421","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Subrion CMS RCE Vulnerability","id":"CVE-2018-19422"},"packages":[],"prev":{"headline":"File upload in n/a","id":"CVE-2018-19420"},"products":["n/a"],"published":"2018-11-21","related":[{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2019-11231","kev_date_added":null,"published":"2019-05-22"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2022-41544","kev_date_added":null,"published":"2022-10-18"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-17103","kev_date_added":null,"published":"2018-09-16"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2014-8722","kev_date_added":null,"published":"2017-03-17"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2020-23839","kev_date_added":null,"published":"2020-09-01"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2013-1420","kev_date_added":null,"published":"2020-01-02"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2018-16325","kev_date_added":null,"published":"2018-09-01"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["n/a"]},"summary":"Attackers can upload malicious .eml files to execute code via Internet Explorer rendering, bypassing HTML upload restrictions in GetSimple CMS.","url":"https://insights.sbomify.com/CVE-2018-19421/"}
