Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-42753 in the wild and no public exploit code.\n\nAffected product: Fortinet Fortiweb. 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-2021-42753/ (Markdown: https://insights.sbomify.com/CVE-2021-42753/index.md)","id":"CVE-2021-42753","markdown":"https://insights.sbomify.com/CVE-2021-42753/index.md","name":"CVE-2021-42753","record":{"aliases":["GHSA-4h43-2654-6c5f"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"FortiWeb WAF","requires_auth":"low_privilege","summary":"An authenticated attacker can delete arbitrary files and directories on FortiWeb devices via a path traversal vulnerability in the management interface.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortiweb","vendor":"fortinet"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H/E:P/RL:U/RC:C","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"An improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability [CWE-22] in FortiWeb management interface 6.4.1 and below, 6.3.15 and below, 6.2.x, 6.1.x, 6.0.x, 5.9.x and 5.8.x may allow an authenticated attacker to perform an arbitrary file and directory deletion in the device filesystem.","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":"Path traversal in n/a","id":"CVE-2021-42753","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fortinet:fortiweb","products":["fortinet:fortiweb"],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in Fortinet FortiClientMac","id":"CVE-2021-42754"},"packages":[],"prev":{"headline":"Cross-site scripting in Fortinet FortiWLM","id":"CVE-2021-42752"},"products":["n/a"],"published":"2022-02-02","related":[{"cvss_score":9.6,"headline":"Fortinet FortiWeb SQL Injection","id":"CVE-2025-25257","kev_date_added":"2025-07-18","published":"2025-07-17"},{"cvss_score":9.4,"headline":"Fortinet FortiWeb Path Traversal","id":"CVE-2025-64446","kev_date_added":"2025-11-14","published":"2025-11-14"},{"cvss_score":6.7,"headline":"Fortinet FortiWeb OS Command Injection","id":"CVE-2025-58034","kev_date_added":"2025-11-18","published":"2025-11-18"},{"cvss_score":9.8,"headline":"SQL injection in Fortinet FortiWeb","id":"CVE-2020-29015","kev_date_added":null,"published":"2021-01-14"},{"cvss_score":9.8,"headline":"Memory corruption in Fortinet FortiWeb","id":"CVE-2020-29016","kev_date_added":null,"published":"2021-01-14"},{"cvss_score":9.3,"headline":"Memory corruption in FortiWeb","id":"CVE-2021-42756","kev_date_added":null,"published":"2023-02-16"},{"cvss_score":9.1,"headline":"Auth bypass in FortiWeb","id":"CVE-2025-59719","kev_date_added":null,"published":"2025-12-09"}],"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":"2024-10-22","vendors":["n/a"]},"summary":"An authenticated attacker can delete arbitrary files and directories on FortiWeb devices via a path traversal vulnerability in the management interface.","url":"https://insights.sbomify.com/CVE-2021-42753/"}
