An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-33021 in the wild and no public exploit code.\n\nAffected product: xArrow SCADA. 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-2021-33021/ (Markdown: https://insights.sbomify.com/CVE-2021-33021/index.md)","id":"CVE-2021-33021","markdown":"https://insights.sbomify.com/CVE-2021-33021/index.md","name":"CVE-2021-33021","record":{"aliases":["GHSA-8c36-rqcc-rv4q"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SCADA system","requires_auth":"none","summary":"An unauthorized attacker can execute arbitrary code via cross-site scripting in the xArrow SCADA system's alarm resource.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"xarrow","vendor":"xarrow"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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":"xArrow SCADA versions 7.2 and prior is vulnerable to cross-site scripting due to parameter ‘edate’ of the resource xhisalarm.htm, which may allow an unauthorized attacker to execute arbitrary code.","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":"xArrow SCADA Cross-site Scripting","id":"CVE-2021-33021","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Philips Vue PACS Cleartext Transmission of Sensitive Information","id":"CVE-2021-33022"},"packages":[],"prev":{"headline":"Philips Vue PACS Use of a Key Past its Expiration Date","id":"CVE-2021-33020"},"products":["xArrow SCADA"],"published":"2022-05-16","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-2427","kev_date_added":null,"published":"2012-05-25"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2012-2428","kev_date_added":null,"published":"2012-05-25"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-2429","kev_date_added":null,"published":"2012-05-25"},{"cvss_score":7.8,"headline":"Null dereference in n/a","id":"CVE-2012-2426","kev_date_added":null,"published":"2012-05-25"},{"cvss_score":6.1,"headline":"xArrow SCADA Cross-site Scripting","id":"CVE-2021-33001","kev_date_added":null,"published":"2022-05-16"},{"cvss_score":5.6,"headline":"xArrow SCADA Path Traversal","id":"CVE-2021-33025","kev_date_added":null,"published":"2022-05-16"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-16","vendors":["xArrow"]},"summary":"An unauthorized attacker can execute arbitrary code via cross-site scripting in the xArrow SCADA system's alarm resource.","url":"https://insights.sbomify.com/CVE-2021-33021/"}
