Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-39277 in the wild and no public exploit code.\n\nAffected product: Sonicwall Sonicos. 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-2023-39277/ (Markdown: https://insights.sbomify.com/CVE-2023-39277/index.md)","id":"CVE-2023-39277","markdown":"https://insights.sbomify.com/CVE-2023-39277/index.md","name":"CVE-2023-39277","record":{"aliases":["GHSA-537g-m9mx-pvhm"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SonicWall firewall","requires_auth":"low_privilege","summary":"Authenticated attackers can crash SonicWall firewalls via a stack-based buffer overflow in specific CSV export endpoints.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sonicwall","cpe":[{"product":"sonicos","vendor":"sonicwall"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"SonicOS post-authentication stack-based buffer overflow vulnerability in the sonicflow.csv and appflowsessions.csv URL endpoints leads to a firewall crash.","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":"Memory corruption in SonicOS","id":"CVE-2023-39277","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"sonicwall:sonicos","products":["sonicwall:sonicos"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in SonicOS","id":"CVE-2023-39278"},"packages":[],"prev":{"headline":"Memory corruption in SonicOS","id":"CVE-2023-39276"},"products":["SonicOS"],"published":"2023-10-17","related":[{"cvss_score":9.8,"headline":"SonicWall SonicOS Buffer Overflow","id":"CVE-2020-5135","kev_date_added":"2022-03-15","published":"2020-10-12"},{"cvss_score":9.3,"headline":"SonicWall SonicOS Improper Access Control","id":"CVE-2024-40766","kev_date_added":"2024-09-09","published":"2024-08-23"},{"cvss_score":8.2,"headline":"SonicWall SonicOS SSLVPN Improper Authentication","id":"CVE-2024-53704","kev_date_added":"2025-02-18","published":"2025-01-09"},{"cvss_score":9.8,"headline":"Denial of service in SonicOS","id":"CVE-2025-40600","kev_date_added":null,"published":"2025-07-29"},{"cvss_score":9.8,"headline":"Auth bypass in SonicOS","id":"CVE-2024-22394","kev_date_added":null,"published":"2024-02-08"},{"cvss_score":9.8,"headline":"Memory corruption in SonicOS","id":"CVE-2022-22274","kev_date_added":null,"published":"2022-03-25"},{"cvss_score":9.8,"headline":"Missing authorization in SonicOS","id":"CVE-2019-7475","kev_date_added":null,"published":"2019-04-02"}],"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":"2024-09-13","vendors":["SonicWall"]},"summary":"Authenticated attackers can crash SonicWall firewalls via a stack-based buffer overflow in specific CSV export endpoints.","url":"https://insights.sbomify.com/CVE-2023-39277/"}
