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-2022-20761 in the wild and no public exploit code.\n\nAffected product: Cisco Ios. 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-2022-20761/ (Markdown: https://insights.sbomify.com/CVE-2022-20761/index.md)","id":"CVE-2022-20761","markdown":"https://insights.sbomify.com/CVE-2022-20761/index.md","name":"CVE-2022-20761","record":{"aliases":["GHSA-7xcx-pr3v-pq9c"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco Connected Grid Router","requires_auth":"none","summary":"An unauthenticated adjacent attacker can cause a denial of service on Cisco CGR1K devices by sending crafted traffic to the integrated wireless access point.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios","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-20","name":"Improper Input Validation"},{"id":"CWE-248","name":"Uncaught Exception"}],"description":"A vulnerability in the integrated wireless access point (AP) packet processing of the Cisco 1000 Series Connected Grid Router (CGR1K) could allow an unauthenticated, adjacent attacker to cause a denial of service 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 to an affected device. A successful exploit could allow the attacker to cause the integrated AP to stop processing traffic, resulting in a DoS condition. It may be necessary to manually reload the CGR1K to restore AP operation.","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 1000 Series Connected Grid Router Integrated Wireless Access Point Denial of Service Vulnerability","id":"CVE-2022-20761","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios","products":["cisco:ios"],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Ultra Cloud Core - Subscriber Microservices Infrastructure Privilege Escalation Vulnerability","id":"CVE-2022-20762"},"packages":[],"prev":{"headline":"Denial of service in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2022-20760"},"products":["Cisco IOS"],"published":"2022-04-15","related":[{"cvss_score":9.8,"headline":"Cisco IOS and IOS XE Software DHCP Remote Code Execution","id":"CVE-2017-12240","kev_date_added":"2022-03-03","published":"2017-09-28"},{"cvss_score":9.8,"headline":"Cisco IOS and IOS XE Remote Code Execution","id":"CVE-2017-3881","kev_date_added":"2022-03-25","published":"2017-03-17"},{"cvss_score":8.8,"headline":"Cisco IOS, XR, and XE Software Buffer Overflow","id":"CVE-2018-0167","kev_date_added":"2022-03-03","published":"2018-03-28"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6736","kev_date_added":"2022-03-03","published":"2017-07-17"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6737","kev_date_added":"2022-03-03","published":"2017-07-17"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6738","kev_date_added":"2022-03-03","published":"2017-07-17"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6739","kev_date_added":"2022-03-03","published":"2017-07-17"}],"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":"2024-11-06","vendors":["Cisco"]},"summary":"An unauthenticated adjacent attacker can cause a denial of service on Cisco CGR1K devices by sending crafted traffic to the integrated wireless access point.","url":"https://insights.sbomify.com/CVE-2022-20761/"}
