An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-24423 in the wild and no public exploit code.\n\nAffected product: Unknown UpdraftPlus WordPress Backup Plugin. 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-2021-24423/ (Markdown: https://insights.sbomify.com/CVE-2021-24423/index.md)","id":"CVE-2021-24423","markdown":"https://insights.sbomify.com/CVE-2021-24423/index.md","name":"CVE-2021-24423","record":{"aliases":["GHSA-4v9q-rjxq-3952"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress backup plugin","requires_auth":"high_privilege","summary":"High-privilege users can inject malicious JavaScript into UpdraftPlus settings, leading to stored cross-site scripting attacks against other administrators.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"updraftplus","vendor":"updraftplus"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The UpdraftPlus WordPress Backup Plugin WordPress plugin before 1.6.59 does not sanitise its updraft_service settings, allowing high privilege users to set malicious JavaScript payload in it and leading to a Stored Cross-Site Scripting issue","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":"UpdraftPlus \u003c 1.16.59 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24423","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"WP Reset \u003c 1.90 - Authenticated Stored XSS","id":"CVE-2021-24424"},"packages":[],"prev":{"headline":"WP JobSearch \u003c 1.7.4 - Authenticated Stored XSS","id":"CVE-2021-24421"},"products":["UpdraftPlus WordPress Backup Plugin"],"published":"2022-01-24","related":[{"cvss_score":8.1,"headline":"Server-side request forgery in n/a","id":"CVE-2017-16870","kev_date_added":null,"published":"2017-11-17"},{"cvss_score":8.1,"headline":"Race condition in n/a","id":"CVE-2017-16871","kev_date_added":null,"published":"2017-11-17"},{"cvss_score":7.1,"headline":"WordPress UpdraftPlus Plugin \u003c= 1.23.3 is vulnerable to Cross Site Request Forgery (CSRF)","id":"CVE-2023-32960","kev_date_added":null,"published":"2023-06-22"},{"cvss_score":6.5,"headline":"UpdraftPlus Free \u003c 1.22.3 \u0026 Premium \u003c 2.22.3 - Subscriber+ Backup Download","id":"CVE-2022-0633","kev_date_added":null,"published":"2022-02-17"},{"cvss_score":6.1,"headline":"UpdraftPlus \u003c 1.22.9 - Reflected Cross-Site Scripting","id":"CVE-2022-0864","kev_date_added":null,"published":"2022-04-04"},{"cvss_score":6.1,"headline":"UpdraftPlus \u003c 1.16.69 - Reflected Cross-Site Scripting","id":"CVE-2021-25089","kev_date_added":null,"published":"2022-02-01"},{"cvss_score":6.1,"headline":"UpdraftPlus \u003c 1.16.66 - Reflected Cross-Site Scripting","id":"CVE-2021-25022","kev_date_added":null,"published":"2022-01-03"}],"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":"2024-08-03","vendors":["Unknown"]},"summary":"High-privilege users can inject malicious JavaScript into UpdraftPlus settings, leading to stored cross-site scripting attacks against other administrators.","url":"https://insights.sbomify.com/CVE-2021-24423/"}
