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-2023-20067 in the wild and no public exploit code.\n\nAffected product: Cisco Ios Xe. 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-2023-20067/ (Markdown: https://insights.sbomify.com/CVE-2023-20067/index.md)","id":"CVE-2023-20067","markdown":"https://insights.sbomify.com/CVE-2023-20067/index.md","name":"CVE-2023-20067","record":{"aliases":["GHSA-vxxf-3gj9-xh73"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco IOS XE WLC","requires_auth":"none","summary":"An unauthenticated adjacent attacker can cause a denial of service on Cisco IOS XE Wireless LAN Controllers by sending crafted traffic through a wireless access point.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios_xe","vendor":"cisco"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A vulnerability in the HTTP-based client profiling feature of Cisco IOS XE Software for Wireless LAN Controllers (WLCs) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of received traffic. An attacker could exploit this vulnerability by sending crafted traffic through a wireless access point. A successful exploit could allow the attacker to cause CPU utilization to increase, which could result in a DoS condition on an affected device and could cause new wireless client associations to fail. Once the offending traffic stops, the affected system will return to an operational state and new client associations will succeed.","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":"Cisco IOS XE Software for Wireless LAN Controllers HTTP Client Profiling Denial of Service Vulnerability","id":"CVE-2023-20067","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios_xe","products":["cisco:ios_xe"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Prime Infrastructure Reflected Cross-Site Scripting Vulnerability","id":"CVE-2023-20068"},"packages":[],"prev":{"headline":"Cisco IOS XE Software Web UI Path Traversal Vulnerability","id":"CVE-2023-20066"},"products":["Cisco IOS XE Software"],"published":"2023-03-23","related":[{"cvss_score":10,"headline":"Cisco IOS XE Web UI Privilege Escalation","id":"CVE-2023-20198","kev_date_added":"2023-10-16","published":"2023-10-16"},{"cvss_score":9.8,"headline":"Cisco IOS Software and Cisco IOS XE Software Quality of Service Remote Code Execution","id":"CVE-2018-0151","kev_date_added":"2022-03-03","published":"2018-03-28"},{"cvss_score":7.2,"headline":"Cisco IOS XE Web UI Command Injection","id":"CVE-2023-20273","kev_date_added":"2023-10-23","published":"2023-10-24"},{"cvss_score":10,"headline":"Hardcoded credentials in Cisco IOS XE Software","id":"CVE-2025-20188","kev_date_added":null,"published":"2025-05-07"},{"cvss_score":10,"headline":"Cisco IOS XE Software for Catalyst 9000 Family Wireless Controllers CAPWAP Remote Code Execution Vulnerability","id":"CVE-2021-34770","kev_date_added":null,"published":"2021-09-23"},{"cvss_score":10,"headline":"Cisco REST API Container for IOS XE Software Authentication Bypass Vulnerability","id":"CVE-2019-12643","kev_date_added":null,"published":"2019-08-28"},{"cvss_score":9.8,"headline":"Cisco IOS XE Software Security Hardening Release","id":"CVE-2026-20272","kev_date_added":null,"published":"2026-08-05"}],"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":["Cisco"]},"summary":"An unauthenticated adjacent attacker can cause a denial of service on Cisco IOS XE Wireless LAN Controllers by sending crafted traffic through a wireless access point.","url":"https://insights.sbomify.com/CVE-2023-20067/"}
