Any signed-in user can exploit it over the network, 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-2021-31250 exists.\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-2021-31250/ (Markdown: https://insights.sbomify.com/CVE-2021-31250/index.md)","id":"CVE-2021-31250","markdown":"https://insights.sbomify.com/CVE-2021-31250/index.md","name":"CVE-2021-31250","record":{"aliases":["GHSA-93wm-fh6p-4cpf"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"TCP/IP Converter","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts into TCP/IP Converter devices via unsanitized input, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"bf-430_firmware","vendor":"chiyu-tech"},{"product":"bf-431_firmware","vendor":"chiyu-tech"},{"product":"bf-450m_firmware","vendor":"chiyu-tech"}],"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":"Multiple storage XSS vulnerabilities were discovered on BF-430, BF-431 and BF-450M TCP/IP Converter devices from CHIYU Technology Inc due to a lack of sanitization of the input on the components man.cgi, if.cgi, dhcpc.cgi, ppp.cgi.","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-2021-31250.yaml","stars":null,"title":"CHIYU TCP/IP Converter - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2021-31250","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Auth bypass in n/a","id":"CVE-2021-31251"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2021-31249"},"products":["n/a"],"published":"2021-06-04","related":[{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2021-31251","kev_date_added":null,"published":"2021-06-04"},{"cvss_score":6.5,"headline":"Other in n/a","id":"CVE-2021-31249","kev_date_added":null,"published":"2021-06-04"},{"cvss_score":6.1,"headline":"Open redirect in n/a","id":"CVE-2021-31252","kev_date_added":null,"published":"2021-06-04"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2021-31641","kev_date_added":null,"published":"2021-06-01"}],"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":["n/a"]},"summary":"Attackers can inject malicious scripts into TCP/IP Converter devices via unsanitized input, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2021-31250/"}
