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-2018-14840 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- intelliants/subrion (Packagist): affected all versions; fixed in 4.2.2\n- intelliants/subrion (Packagist): affected all versions; fixed in 4.2.2\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-2018-14840/ (Markdown: https://insights.sbomify.com/CVE-2018-14840/index.md)","id":"CVE-2018-14840","markdown":"https://insights.sbomify.com/CVE-2018-14840/index.md","name":"CVE-2018-14840","record":{"aliases":["GHSA-vhqr-3gr2-7px9"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Subrion CMS","requires_auth":"none","summary":"Attackers can upload malicious HTML files to execute scripts in the context of other users, potentially leading to session hijacking or site defacement.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"subrion","vendor":"intelliants"}],"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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"uploads/.htaccess in Subrion CMS 4.2.1 allows XSS because it does not block .html file uploads (but does block, for example, .htm file uploads).","ecosystems":["Packagist"],"exploits":{"exploitdb":1,"first_seen":"2018-08-06","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2018-08-06","kind":"exploitdb","ref":"45150","stars":null,"title":"Subrion CMS 4.2.1 - Cross-Site Scripting"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Subrion CMS Cross-site Scripting","id":"CVE-2018-14840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2018"},"n_packages":2,"n_references":3,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-14846"},"packages":[{"ecosystem":"Packagist","fixed":["4.2.2"],"introduced":["0"],"last_affected":[],"package":"intelliants/subrion","purl":null,"source":"GHSA-vhqr-3gr2-7px9"},{"ecosystem":"Packagist","fixed":["4.2.2"],"introduced":["0"],"last_affected":[],"package":"intelliants/subrion","purl":"pkg:composer/intelliants/subrion","source":"GHSA-vhqr-3gr2-7px9"}],"prev":{"headline":"LG N1A1 NAS Remote Command Execution","id":"CVE-2018-14839"},"products":["n/a"],"published":"2018-08-02","related":[{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2024-25400","kev_date_added":null,"published":"2024-02-27"},{"cvss_score":9.8,"headline":"SQL Injection in Subrion CMS","id":"CVE-2020-18155","kev_date_added":null,"published":"2021-07-14"},{"cvss_score":9.8,"headline":"Subrion CMS PHP Object Injection","id":"CVE-2017-5543","kev_date_added":null,"published":"2017-01-20"},{"cvss_score":8.8,"headline":"Subrion remote command execution vulnerability","id":"CVE-2023-46947","kev_date_added":null,"published":"2023-11-03"},{"cvss_score":8.8,"headline":"Subrion CMS CSRF Vulnerability","id":"CVE-2018-21037","kev_date_added":null,"published":"2020-03-17"},{"cvss_score":8.8,"headline":"Subrion CMS CSRF Vulnerability","id":"CVE-2017-15063","kev_date_added":null,"published":"2017-10-06"},{"cvss_score":8.1,"headline":"Subrion CMS Cross-Site Request Forgery (CSRF) vulnerability","id":"CVE-2019-20390","kev_date_added":null,"published":"2020-05-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can upload malicious HTML files to execute scripts in the context of other users, potentially leading to session hijacking or site defacement.","url":"https://insights.sbomify.com/CVE-2018-14840/"}
