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-2021-24856 in the wild and no public exploit code.\n\nAffected product: Unknown Shared Files – Easy Download Manager and File Sharing Plugin with Frontend File Upload. 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-2021-24856/ (Markdown: https://insights.sbomify.com/CVE-2021-24856/index.md)","id":"CVE-2021-24856","markdown":"https://insights.sbomify.com/CVE-2021-24856/index.md","name":"CVE-2021-24856","record":{"aliases":["GHSA-533w-p83m-xgjp"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"High-privilege users can inject malicious scripts via Download Counter Text settings in the Shared Files WordPress plugin, potentially leading to code execution or account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"shared_files","vendor":"tammersoft"}],"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 Shared Files WordPress plugin before 1.6.61 does not sanitise and escape the Download Counter Text settings, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed","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":"Shared Files \u003c 1.6.61 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24856","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"ToTop Link \u003c= 1.7.1 - Unauthenticated PHP Object Injection","id":"CVE-2021-24857"},"packages":[],"prev":{"headline":"Display Post Metadata \u003c 1.5.0 - Contributor+ Stored Cross-Site Scripting","id":"CVE-2021-24855"},"products":["Shared Files – Easy Download Manager and File Sharing Plugin with Frontend File Upload"],"published":"2021-11-17","related":[{"cvss_score":6.1,"headline":"Shared Files \u003c 1.7.6 - Unauthenticated Stored Cross-Site Scripting","id":"CVE-2023-4819","kev_date_added":null,"published":"2023-10-16"},{"cvss_score":4.8,"headline":"Shared Files \u003c 1.6.57 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24736","kev_date_added":null,"published":"2021-10-18"}],"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 scripts via Download Counter Text settings in the Shared Files WordPress plugin, potentially leading to code execution or account takeover.","url":"https://insights.sbomify.com/CVE-2021-24856/"}
