An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20034 in the wild and no public exploit code.\n\nAffected product: SonicWall SMA100. 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-2021-20034/ (Markdown: https://insights.sbomify.com/CVE-2021-20034/index.md)","id":"CVE-2021-20034","markdown":"https://insights.sbomify.com/CVE-2021-20034/index.md","name":"CVE-2021-20034","record":{"aliases":["GHSA-vfqg-fwg4-f3vx"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SonicWall SMA100","requires_auth":"none","summary":"Remote unauthenticated attackers can bypass path traversal checks to delete arbitrary files, potentially forcing a factory reset on SonicWall SMA100 devices.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sonicwall","cpe":[{"product":"sma_200_firmware","vendor":"sonicwall"},{"product":"sma_210_firmware","vendor":"sonicwall"},{"product":"sma_400_firmware","vendor":"sonicwall"},{"product":"sma_410_firmware","vendor":"sonicwall"},{"product":"sma_500v","vendor":"sonicwall"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"An improper access control vulnerability in SMA100 allows a remote unauthenticated attacker to bypass the path traversal checks and delete an arbitrary file potentially resulting in a reboot to factory default settings.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2021-10-20","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-10-20","kind":"exploitdb","ref":"50430","stars":null,"title":"SonicWall SMA 10.2.1.0-17sv - Password Reset"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Path traversal in SMA100","id":"CVE-2021-20034","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"SonicWall SMA100 Appliances OS Command Injection","id":"CVE-2021-20035"},"packages":[],"prev":{"headline":"Misconfiguration in SonicWall Analytics On-Prem","id":"CVE-2021-20032"},"products":["SMA100"],"published":"2021-09-27","related":[{"cvss_score":9.8,"headline":"SonicWall SMA 100 Appliances Stack-Based Buffer Overflow","id":"CVE-2021-20038","kev_date_added":"2022-01-28","published":"2021-12-08"},{"cvss_score":7.2,"headline":"SonicWall SMA100 Appliances OS Command Injection","id":"CVE-2023-44221","kev_date_added":"2025-05-01","published":"2023-12-05"},{"cvss_score":6.5,"headline":"SonicWall SMA100 Appliances OS Command Injection","id":"CVE-2021-20035","kev_date_added":"2025-04-16","published":"2021-09-27"},{"cvss_score":9.8,"headline":"Command injection in SonicWall SRA/SMA100","id":"CVE-2022-22273","kev_date_added":null,"published":"2022-03-17"},{"cvss_score":9.8,"headline":"Server-side request forgery in SonicWall SMA100","id":"CVE-2021-20042","kev_date_added":null,"published":"2021-12-08"},{"cvss_score":9.8,"headline":"Memory corruption in SonicWall SMA100","id":"CVE-2021-20045","kev_date_added":null,"published":"2021-12-08"}],"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":"2024-08-03","vendors":["SonicWall"]},"summary":"Remote unauthenticated attackers can bypass path traversal checks to delete arbitrary files, potentially forcing a factory reset on SonicWall SMA100 devices.","url":"https://insights.sbomify.com/CVE-2021-20034/"}
