An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-24495 exists.\n\nAffected product: Unknown Marmoset Viewer. 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-2021-24495/ (Markdown: https://insights.sbomify.com/CVE-2021-24495/index.md)","id":"CVE-2021-24495","markdown":"https://insights.sbomify.com/CVE-2021-24495/index.md","name":"CVE-2021-24495","record":{"aliases":["GHSA-4r3v-6fhp-p4mw"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Reflected Cross-Site Scripting in Marmoset Viewer WordPress plugin allows attackers to inject malicious scripts via the id parameter.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"marmoset_viewer","vendor":"marmoset"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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 Marmoset Viewer WordPress plugin before 1.9.3 does not property sanitize, validate or escape the 'id' parameter before outputting back in the page, leading to a reflected Cross-Site Scripting issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-24495.yaml","stars":null,"title":"Wordpress Marmoset Viewer \u003c1.9.3 - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":null,"headline":"Marmoset Viewer \u003c 1.9.3 - Reflected Cross Site Scripting","id":"CVE-2021-24495","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Community Event \u003c 1.4.8 - Reflected Cross-Site Scripting (XSS)","id":"CVE-2021-24496"},"packages":[],"prev":{"headline":"WP Offload SES Lite \u003c 1.4.5 - Stored Cross-Site Scripting (XSS)","id":"CVE-2021-24494"},"products":["Marmoset Viewer"],"published":"2021-08-09","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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"Reflected Cross-Site Scripting in Marmoset Viewer WordPress plugin allows attackers to inject malicious scripts via the id parameter.","url":"https://insights.sbomify.com/CVE-2021-24495/"}
