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-2021-27933 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-2021-27933/ (Markdown: https://insights.sbomify.com/CVE-2021-27933/index.md)","id":"CVE-2021-27933","markdown":"https://insights.sbomify.com/CVE-2021-27933/index.md","name":"CVE-2021-27933","record":{"aliases":["GHSA-wx6c-2hx8-x9gx"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"pfSense firewall","requires_auth":"none","summary":"Cross-site scripting vulnerability in pfSense allows attackers to inject malicious scripts via the Wake-on-LAN description field.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pfsense","vendor":"pfsense"}],"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":"pfSense 2.5.0 allows XSS via the services_wol_edit.php Description field.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Cross-site scripting in n/a","id":"CVE-2021-27933","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in n/a","id":"CVE-2021-27935"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2021-27932"},"products":["n/a"],"published":"2021-04-28","related":[{"cvss_score":9.9,"headline":"Code injection in n/a","id":"CVE-2025-69691","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":9.8,"headline":"Weak cryptography in n/a","id":"CVE-2023-29974","kev_date_added":null,"published":"2023-11-08"},{"cvss_score":9.1,"headline":"Deserialization in n/a","id":"CVE-2025-69690","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2021-41282","kev_date_added":null,"published":"2022-03-01"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2016-10709","kev_date_added":null,"published":"2018-01-22"},{"cvss_score":8.6,"headline":"Netgate pfSense CE 2.7.0 through 2.9.0 OS Command Injection via interfaces_qinq_edit.php","id":"CVE-2026-111214","kev_date_added":null,"published":"2026-10-15"},{"cvss_score":8.6,"headline":"Netgate pfSense CE through 2.9.0 OS Command Injection via Wireless Parent Interface","id":"CVE-2026-111215","kev_date_added":null,"published":"2026-10-15"}],"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":["n/a"]},"summary":"Cross-site scripting vulnerability in pfSense allows attackers to inject malicious scripts via the Wake-on-LAN description field.","url":"https://insights.sbomify.com/CVE-2021-27933/"}
