It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-26088 and fix it if it is affected.\n\nWhat it is: CVE-2021-26088 is a high-severity authentication bypass vulnerability in Fortinet FSSO Windows DC Agent, FSSO Windows CA, published on 12 Jul 2021. 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-2021-26088 in the wild and no public exploit code.\n\nAffected product: Fortinet FSSO Windows DC Agent, FSSO Windows CA. 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-2021-26088/ (Markdown: https://insights.sbomify.com/CVE-2021-26088/index.md)","id":"CVE-2021-26088","markdown":"https://insights.sbomify.com/CVE-2021-26088/index.md","name":"CVE-2021-26088","record":{"aliases":["GHSA-pp6p-mhjc-6vgp"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Fortinet FSSO Collector","requires_auth":"none","summary":"Unauthenticated attackers can bypass firewall policies and access protected networks by sending crafted UDP packets to the FSSO Collector.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortinet_single_sign-on","vendor":"fortinet"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"An improper authentication vulnerability in FSSO Collector version 5.0.295 and below may allow an unauthenticated user to bypass a FSSO firewall policy and access the protected network via sending specifically crafted UDP login notification packets.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-05-09","github_poc":1,"max_poc_stars":3,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-05-09T13:13:41Z","kind":"github_poc","ref":"https://github.com/theogobinet/CVE-2021-26088","stars":3,"title":"PoC for CVE-2021-26088 written in PowerShell"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Auth bypass in Fortinet FSSO Windows DC Agent, FSSO Windows CA","id":"CVE-2021-26088","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Fortinet FortiClientMac","id":"CVE-2021-26089"},"packages":[],"prev":{"headline":"Cross-site scripting in FortiWLC","id":"CVE-2021-26087"},"products":["Fortinet FSSO Windows DC Agent, FSSO Windows CA"],"published":"2021-07-12","related":[],"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":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-25","vendors":["Fortinet"]},"summary":"Unauthenticated attackers can bypass firewall policies and access protected networks by sending crafted UDP packets to the FSSO Collector.","url":"https://insights.sbomify.com/CVE-2021-26088/"}
