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-2021-45905 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-2021-45905/ (Markdown: https://insights.sbomify.com/CVE-2021-45905/index.md)","id":"CVE-2021-45905","markdown":"https://insights.sbomify.com/CVE-2021-45905/index.md","name":"CVE-2021-45905","record":{"aliases":["GHSA-8mgx-6xjm-hg5q"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenWrt router OS","requires_auth":"low_privilege","summary":"An attacker can inject malicious scripts via the Traffic Rules Name screen in OpenWrt, potentially leading to session hijacking or code execution.","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":"OpenWrt 21.02.1 allows XSS via the Traffic Rules Name screen.","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-2021-45905","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":"Cross-site scripting in n/a","id":"CVE-2021-45906"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-45904"},"products":["n/a"],"published":"2021-12-27","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":"2024-08-04","vendors":["n/a"]},"summary":"An attacker can inject malicious scripts via the Traffic Rules Name screen in OpenWrt, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2021-45905/"}
