An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-42751 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-2021-42751/ (Markdown: https://insights.sbomify.com/CVE-2021-42751/index.md)","id":"CVE-2021-42751","markdown":"https://insights.sbomify.com/CVE-2021-42751/index.md","name":"CVE-2021-42751","record":{"aliases":["GHSA-cm2p-96gm-hwf2"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"ThingsBoard IoT platform","requires_auth":"high_privilege","summary":"Remote attackers with administrative access can inject arbitrary JavaScript into rule node descriptions in ThingsBoard, potentially leading to code execution or account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"thingsboard","vendor":"thingsboard"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/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 cross-site scripting (XSS) vulnerability in Rule Engine in ThingsBoard 3.3.1 allows remote attackers (with administrative access) to inject arbitrary JavaScript within the description of a rule node.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2022-08-09","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2022-08-09","kind":"exploitdb","ref":"51004","stars":null,"title":"ThingsBoard 3.3.1 'description' - Stored Cross-Site Scripting (XSS)"}],"tier":"poc_unverified"},"has_fix":false,"headline":"Cross-site scripting in n/a","id":"CVE-2021-42751","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Fortinet FortiWLM","id":"CVE-2021-42752"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-42750"},"products":["n/a"],"published":"2022-08-12","related":[{"cvss_score":9.6,"headline":"Cross-site scripting in n/a","id":"CVE-2022-40004","kev_date_added":null,"published":"2022-12-15"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2022-45608","kev_date_added":null,"published":"2023-03-01"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2022-48341","kev_date_added":null,"published":"2023-02-23"},{"cvss_score":8.8,"headline":"Open redirect in n/a","id":"CVE-2020-27687","kev_date_added":null,"published":"2020-12-18"},{"cvss_score":8.4,"headline":"ThingsBoard Server-Side Template Injection","id":"CVE-2023-45303","kev_date_added":null,"published":"2023-10-06"},{"cvss_score":8.1,"headline":"Hardcoded credentials in n/a","id":"CVE-2023-26462","kev_date_added":null,"published":"2023-02-23"},{"cvss_score":6.9,"headline":"ThingsBoard \u003c v4.2.1 SVG Image SSRF","id":"CVE-2025-34282","kev_date_added":null,"published":"2025-10-17"}],"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":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers with administrative access can inject arbitrary JavaScript into rule node descriptions in ThingsBoard, potentially leading to code execution or account takeover.","url":"https://insights.sbomify.com/CVE-2021-42751/"}
