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-2021-31643 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-2021-31643/ (Markdown: https://insights.sbomify.com/CVE-2021-31643/index.md)","id":"CVE-2021-31643","markdown":"https://insights.sbomify.com/CVE-2021-31643/index.md","name":"CVE-2021-31643","record":{"aliases":["GHSA-hxrr-8f87-qrgp"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"IoT device firmware","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary scripts via the username parameter in if.cgi on CHIYU Technology IoT devices, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"bf-630_firmware","vendor":"chiyu-tech"},{"product":"bf-631_firmware","vendor":"chiyu-tech"},{"product":"biosense_firmware","vendor":"chiyu-tech"},{"product":"semac_d1_firmware","vendor":"chiyu-tech"},{"product":"semac_d2_firmware","vendor":"chiyu-tech"},{"product":"semac_d2_n300_firmware","vendor":"chiyu-tech"},{"product":"semac_d4_firmware","vendor":"chiyu-tech"},{"product":"semac_s1_osdp_firmware","vendor":"chiyu-tech"},{"product":"semac_s2_firmware","vendor":"chiyu-tech"},{"product":"semac_s3v3_firmware","vendor":"chiyu-tech"},{"product":"webpass_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":"An XSS vulnerability exists in several IoT devices from CHIYU Technology, including SEMAC, Biosense, BF-630, BF-631, and Webpass due to a lack of sanitization on the component if.cgi - username parameter.","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-2021-31643","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":4,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-31645"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2021-31642"},"products":["n/a"],"published":"2021-06-01","related":[{"cvss_score":6.5,"headline":"Integer overflow in n/a","id":"CVE-2021-31642","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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can execute arbitrary scripts via the username parameter in if.cgi on CHIYU Technology IoT devices, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2021-31643/"}
