It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-42082 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-2021-42082/ (Markdown: https://insights.sbomify.com/CVE-2021-42082/index.md)","id":"CVE-2021-42082","markdown":"https://insights.sbomify.com/CVE-2021-42082/index.md","name":"CVE-2021-42082","record":{"aliases":["GHSA-3x7w-vvg2-w6r8"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Storage management software","requires_auth":"low_privilege","summary":"Local attackers can execute arbitrary commands as root via command injection in the upgrade script, leading to full system compromise.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"DIVD","cpe":[{"product":"quantastor","vendor":"osnexus"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Local users are able to execute scripts under root privileges.\n\nPOC\n\nOn the local host run the following command:\n\ncurl 'localhost:8154/qstor/qs_upgrade.py?taskId=1\u0026a=;`whoami`'","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":"Local Privilege Escalation to root in OSNEXUS QuantaStor before 6.0.0.355","id":"CVE-2021-42082","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":4,"next":{"headline":"Authenticated Stored XSS in OSNEXUS QuantaStor 6.0.0.335","id":"CVE-2021-42083"},"packages":[],"prev":{"headline":"Authenticated Remote Command Execution vulnerability in OSNEXUS QuantaStor before 6.0.0.355","id":"CVE-2021-42081"},"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":8.7,"headline":"Authenticated Stored XSS in OSNEXUS QuantaStor 6.0.0.335","id":"CVE-2021-42083","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-09-22","vendors":["OSNEXUS"]},"summary":"Local attackers can execute arbitrary commands as root via command injection in the upgrade script, leading to full system compromise.","url":"https://insights.sbomify.com/CVE-2021-42082/"}
