Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-16484 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- m-server (npm): affected all versions; fixed in 1.4.2\n- m-server (npm): affected all versions; fixed in 1.4.2\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-2018-16484/ (Markdown: https://insights.sbomify.com/CVE-2018-16484/index.md)","id":"CVE-2018-16484","markdown":"https://insights.sbomify.com/CVE-2018-16484/index.md","name":"CVE-2018-16484","record":{"aliases":["GHSA-gmxv-xf2q-6j8m"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js server module","requires_auth":"low_privilege","summary":"An attacker can execute malicious JavaScript or HTML via unescaped folder names in the m-server module, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"m-server","vendor":"m-server_project"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/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":"A XSS vulnerability was found in module m-server \u003c1.4.2 that allows malicious Javascript code or HTML to be executed, due to the lack of escaping for special characters in folder names.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Cross-Site Scripting in m-server","id":"CVE-2018-16484","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2018"},"n_packages":2,"n_references":1,"next":{"headline":"m-server Vulnerable to Directory Traversal","id":"CVE-2018-16485"},"packages":[{"ecosystem":"npm","fixed":["1.4.2"],"introduced":["0"],"last_affected":[],"package":"m-server","purl":null,"source":"GHSA-gmxv-xf2q-6j8m"},{"ecosystem":"npm","fixed":["1.4.2"],"introduced":["0"],"last_affected":[],"package":"m-server","purl":"pkg:npm/m-server","source":"GHSA-gmxv-xf2q-6j8m"}],"prev":{"headline":"Authentication Bypass by Spoofing in express-cart","id":"CVE-2018-16483"},"products":["m-server"],"published":"2019-02-01","related":[{"cvss_score":6.5,"headline":"m-server Vulnerable to Directory Traversal","id":"CVE-2018-16485","kev_date_added":null,"published":"2019-02-01"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["HackerOne"]},"summary":"An attacker can execute malicious JavaScript or HTML via unescaped folder names in the m-server module, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2018-16484/"}
