Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-26096 in the wild and no public exploit code.\n\nAffected product: Fortinet Fortisandbox. 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-2021-26096/ (Markdown: https://insights.sbomify.com/CVE-2021-26096/index.md)","id":"CVE-2021-26096","markdown":"https://insights.sbomify.com/CVE-2021-26096/index.md","name":"CVE-2021-26096","record":{"aliases":["GHSA-w667-46wg-c64r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Fortinet FortiSandbox","requires_auth":"low_privilege","summary":"An authenticated attacker can exploit heap-based buffer overflows in FortiSandbox to manipulate memory and potentially execute arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortisandbox","vendor":"fortinet"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:L/E:X/RL:X/RC:X","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Multiple instances of heap-based buffer overflow in the command shell of FortiSandbox before 4.0.0 may allow an authenticated attacker to manipulate memory and alter its content by means of specifically crafted command line arguments.","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 Fortinet FortiSandbox","id":"CVE-2021-26096","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fortinet:fortisandbox","products":["fortinet:fortisandbox"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in Fortinet FortiSandbox","id":"CVE-2021-26097"},"packages":[],"prev":{"headline":"Weak cryptography in Fortinet FortiMail","id":"CVE-2021-26095"},"products":["Fortinet FortiSandbox"],"published":"2021-08-04","related":[{"cvss_score":9.1,"headline":"Fortinet FortiSandbox OS Command Injection","id":"CVE-2026-25089","kev_date_added":"2026-07-16","published":"2026-06-09"},{"cvss_score":9.1,"headline":"Fortinet FortiSandbox OS Command Injection","id":"CVE-2026-39808","kev_date_added":"2026-07-16","published":"2026-04-14"},{"cvss_score":9.1,"headline":"Missing authorization in FortiSandbox","id":"CVE-2026-26083","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":9.1,"headline":"Path traversal in FortiSandbox","id":"CVE-2026-39813","kev_date_added":null,"published":"2026-04-14"},{"cvss_score":8.8,"headline":"SQL injection in Fortinet FortiSandbox","id":"CVE-2020-29011","kev_date_added":null,"published":"2021-08-04"},{"cvss_score":8.8,"headline":"Command injection in Fortinet FortiSandbox","id":"CVE-2021-26097","kev_date_added":null,"published":"2021-08-04"},{"cvss_score":8.6,"headline":"Command injection in FortiSandbox","id":"CVE-2024-52961","kev_date_added":null,"published":"2025-03-11"}],"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":"2024-10-25","vendors":["Fortinet"]},"summary":"An authenticated attacker can exploit heap-based buffer overflows in FortiSandbox to manipulate memory and potentially execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2021-26096/"}
