Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-33425 in the wild and no public exploit code.\n\nAffected product: Openwrt Openwrt. 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-2021-33425/ (Markdown: https://insights.sbomify.com/CVE-2021-33425/index.md)","id":"CVE-2021-33425","markdown":"https://insights.sbomify.com/CVE-2021-33425/index.md","name":"CVE-2021-33425","record":{"aliases":["GHSA-c35r-9rpc-98gc"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenWRT LuCI","requires_auth":"low_privilege","summary":"Attackers can inject arbitrary JavaScript via the hostname field in OpenWRT LuCI, potentially executing code in the admin interface.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openwrt","vendor":"openwrt"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"A stored cross-site scripting (XSS) vulnerability was discovered in the Web Interface for OpenWRT LuCI version 19.07 which allows attackers to inject arbitrary Javascript in the OpenWRT Hostname via the Hostname Change operation.","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-2021-33425","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openwrt:openwrt","products":["openwrt:openwrt"],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"NumPy Buffer Overflow (Disputed)","id":"CVE-2021-33430"},"packages":[],"prev":{"headline":"replicator vulnerable to Deserialization of Untrusted Data","id":"CVE-2021-33420"},"products":["n/a"],"published":"2021-05-25","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-28951","kev_date_added":null,"published":"2020-11-19"},{"cvss_score":9.6,"headline":"Cross-site scripting in openwrt","id":"CVE-2026-62948","kev_date_added":null,"published":"2026-07-15"},{"cvss_score":9.5,"headline":"OpenWrt Project has Stack-based Buffer Overflow in DNS PTR Query","id":"CVE-2026-30871","kev_date_added":null,"published":"2026-03-19"},{"cvss_score":9.5,"headline":"OpenWrt Project has a Stack-based Buffer Overflow vulnerability via IPv6 reverse DNS lookup","id":"CVE-2026-30872","kev_date_added":null,"published":"2026-03-19"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2021-28961","kev_date_added":null,"published":"2021-03-21"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2019-17367","kev_date_added":null,"published":"2019-10-18"},{"cvss_score":8.8,"headline":"Missing authorization in n/a","id":"CVE-2018-11116","kev_date_added":null,"published":"2018-06-19"}],"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":"2026-07-09","vendors":["n/a"]},"summary":"Attackers can inject arbitrary JavaScript via the hostname field in OpenWRT LuCI, potentially executing code in the admin interface.","url":"https://insights.sbomify.com/CVE-2021-33425/"}
