An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-27100 exists.\n\nAffected product: n/a. 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-2023-27100/ (Markdown: https://insights.sbomify.com/CVE-2023-27100/index.md)","id":"CVE-2023-27100","markdown":"https://insights.sbomify.com/CVE-2023-27100/index.md","name":"CVE-2023-27100","record":{"aliases":["GHSA-wmh3-5pfq-qpp8"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"pfSense firewall","requires_auth":"none","summary":"Attackers can bypass SSHGuard brute force protection in pfSense via crafted web requests, allowing continued authentication attempts.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pfsense_plus","vendor":"netgate"},{"product":"pfsense","vendor":"pfsense"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"Improper restriction of excessive authentication attempts in the SSHGuard component of Netgate pfSense Plus software v22.05.1 and pfSense CE software v2.6.0 allows attackers to bypass brute force protection mechanisms via crafted web requests.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2023-04-08","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-04-08","kind":"exploitdb","ref":"51352","stars":null,"title":"pfsenseCE v2.6.0 - Anti-brute force protection bypass"},{"date":"2024-05-20T13:35:39Z","kind":"github_poc","ref":"https://github.com/fabdotnet/CVE-2023-27100","stars":0,"title":null}],"tier":"weaponised"},"has_fix":null,"headline":"Security feature bypass in n/a","id":"CVE-2023-27100","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Null dereference in n/a","id":"CVE-2023-27102"},"packages":[],"prev":{"headline":"Hardcoded credentials in n/a","id":"CVE-2023-27098"},"products":["n/a"],"published":"2023-03-22","related":[{"cvss_score":6.1,"headline":"Cross-site scripting in pfSense CE and pfSense Plus","id":"CVE-2021-20729","kev_date_added":null,"published":"2022-03-31"}],"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"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-25","vendors":["n/a"]},"summary":"Attackers can bypass SSHGuard brute force protection in pfSense via crafted web requests, allowing continued authentication attempts.","url":"https://insights.sbomify.com/CVE-2023-27100/"}
