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-2021-41823 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-2021-41823/ (Markdown: https://insights.sbomify.com/CVE-2021-41823/index.md)","id":"CVE-2021-41823","markdown":"https://insights.sbomify.com/CVE-2021-41823/index.md","name":"CVE-2021-41823","record":{"aliases":["GHSA-8q3m-vc4w-chfw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"LoadMaster WAF","requires_auth":"none","summary":"An XSS protection bypass in Kemp LoadMaster WAF allows attackers to execute scripts via onmouseover events, requiring a software upgrade.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"web_application_firewall","vendor":"kemptechnologies"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","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 Web Application Firewall (WAF) in Kemp LoadMaster 7.2.54.1 allows certain uses of onmouseover to bypass an XSS protection mechanism.","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-2021-41823","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"CSV Injection Vulnerability","id":"CVE-2021-41824"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2021-41821"},"products":["n/a"],"published":"2023-01-01","related":[{"cvss_score":9.1,"headline":"Security feature bypass in n/a","id":"CVE-2017-15524","kev_date_added":null,"published":"2017-12-18"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-11","vendors":["n/a"]},"summary":"An XSS protection bypass in Kemp LoadMaster WAF allows attackers to execute scripts via onmouseover events, requiring a software upgrade.","url":"https://insights.sbomify.com/CVE-2021-41823/"}
