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-2021-42083 in the wild and no public exploit code.\n\nAffected product: OSNEXUS QuantaStor. 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-2021-42083/ (Markdown: https://insights.sbomify.com/CVE-2021-42083/index.md)","id":"CVE-2021-42083","markdown":"https://insights.sbomify.com/CVE-2021-42083/index.md","name":"CVE-2021-42083","record":{"aliases":["GHSA-9c8q-55w7-h67h"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Storage management software","requires_auth":"low_privilege","summary":"Authenticated attackers can inject malicious scripts via webhook URLs in QuantaStor, leading to remote code execution with root privileges.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"DIVD","cpe":[{"product":"quantastor","vendor":"osnexus"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"An authenticated attacker is able to create alerts that trigger a stored XSS attack.\n\nPOC\n\n  *  go to the alert manager\n\n  *  open the ITSM tab\n  *  add a webhook with the URL/service token value \n\n'\t-h\t\u0026\u0026\tid\t|\ttee\t/tmp/ttttttddddssss\t#' (whitespaces are tab characters)\n\n  *  click add\n\n  *  click apply\n\n  *  create a test alert\n\n  *  The test alert will run the command \n\n“id\t|\ttee\t/tmp/ttttttddddssss” as root.\n\n  *  after the test alert inspect \n\n/tmp/ttttttddddssss it'll contain the ids of the root user.","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":"Authenticated Stored XSS in OSNEXUS QuantaStor 6.0.0.335","id":"CVE-2021-42083","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-2021-42084"},"packages":[],"prev":{"headline":"Local Privilege Escalation to root in OSNEXUS QuantaStor before 6.0.0.355","id":"CVE-2021-42082"},"products":["QuantaStor"],"published":"2023-07-10","related":[{"cvss_score":9.1,"headline":"Authenticated Remote Command Execution vulnerability in OSNEXUS QuantaStor before 6.0.0.355","id":"CVE-2021-42081","kev_date_added":null,"published":"2023-07-10"},{"cvss_score":9.1,"headline":"Authenticated Remote COmmand Execution as root in OSNEXUS QuantaStor version 6.0.0.355 and others","id":"CVE-2021-4406","kev_date_added":null,"published":"2023-07-10"},{"cvss_score":7.8,"headline":"Local Privilege Escalation to root in OSNEXUS QuantaStor before 6.0.0.355","id":"CVE-2021-42082","kev_date_added":null,"published":"2023-07-10"},{"cvss_score":7.4,"headline":"Reflected XSS vulnerability in OSNEXUS QuantaStor before 6.0.0.355","id":"CVE-2021-42080","kev_date_added":null,"published":"2023-07-10"},{"cvss_score":6.2,"headline":"SSRF vulnerability in OSNEXUS QuantaStor before 6.0.0.355","id":"CVE-2021-42079","kev_date_added":null,"published":"2023-07-10"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2017-9979","kev_date_added":null,"published":"2017-08-28"}],"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":"2025-09-22","vendors":["OSNEXUS"]},"summary":"Authenticated attackers can inject malicious scripts via webhook URLs in QuantaStor, leading to remote code execution with root privileges.","url":"https://insights.sbomify.com/CVE-2021-42083/"}
