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-2021-40909 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-2021-40909/ (Markdown: https://insights.sbomify.com/CVE-2021-40909/index.md)","id":"CVE-2021-40909","markdown":"https://insights.sbomify.com/CVE-2021-40909/index.md","name":"CVE-2021-40909","record":{"aliases":["GHSA-vqxh-g4gf-cp2w"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP CRUD tutorial","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via XSS in the first_name, last_name, and email parameters of this PHP CRUD application.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"php_crud_without_refresh\\/reload_using_ajax_and_datatables_tutorial","vendor":"php_crud_without_refresh\\/reload_using_ajax_and_datatables_tutorial_project"}],"cvss":{"score":9.6,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross site scripting (XSS) vulnerability in sourcecodester PHP CRUD without Refresh/Reload using Ajax and DataTables Tutorial v1 by oretnom23, allows remote attackers to execute arbitrary code via the first_name, last_name, and email parameters to /ajax_crud.","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":"Cross-site scripting in n/a","id":"CVE-2021-40909","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-40910"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2021-40908"},"products":["n/a"],"published":"2022-01-24","related":[],"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":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via XSS in the first_name, last_name, and email parameters of this PHP CRUD application.","url":"https://insights.sbomify.com/CVE-2021-40909/"}
