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-2024-20319 in the wild and no public exploit code.\n\nAffected product: Cisco Ios Xr. 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-2024-20319/ (Markdown: https://insights.sbomify.com/CVE-2024-20319/index.md)","id":"CVE-2024-20319","markdown":"https://insights.sbomify.com/CVE-2024-20319/index.md","name":"CVE-2024-20319","record":{"aliases":["GHSA-936v-x9xm-gc22"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Cisco IOS XR","requires_auth":"none","summary":"An unauthenticated adjacent attacker can bypass management plane protection to access the SNMP server on Cisco IOS XR devices.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios_xr","vendor":"cisco"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A vulnerability in the UDP forwarding code of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to bypass configured management plane protection policies and access the Simple Network Management Plane (SNMP) server of an affected device.\r\n\r This vulnerability is due to incorrect UDP forwarding programming when using SNMP with management plane protection. An attacker could exploit this vulnerability by attempting to perform an SNMP operation using broadcast as the destination address that could be processed by an affected device that is configured with an SNMP server. A successful exploit could allow the attacker to communicate to the device on the configured SNMP ports. Although an unauthenticated attacker could send UDP datagrams to the configured SNMP port, only an authenticated user can retrieve or modify data using SNMP requests.","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":"Security feature bypass in Cisco IOS XR Software","id":"CVE-2024-20319","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios_xr","products":["cisco:ios_xr"],"type":"security_feature_bypass","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Cisco IOS XR Software","id":"CVE-2024-20320"},"packages":[],"prev":{"headline":"Denial of service in Cisco IOS XR Software","id":"CVE-2024-20318"},"products":["Cisco IOS XR Software"],"published":"2024-03-13","related":[{"cvss_score":8.8,"headline":"Cisco IOS XR Software Discovery Protocol Format String","id":"CVE-2020-3118","kev_date_added":"2021-11-03","published":"2020-02-05"},{"cvss_score":8.6,"headline":"Cisco IOS XR Software DVMRP Memory Exhaustion","id":"CVE-2020-3569","kev_date_added":"2021-11-03","published":"2020-09-23"},{"cvss_score":8.6,"headline":"Cisco IOS XR Software DVMRP Memory Exhaustion","id":"CVE-2020-3566","kev_date_added":"2021-11-03","published":"2020-08-29"},{"cvss_score":7.5,"headline":"Cisco IOS XR Border Gateway Protocol (BGP) Denial-of-Service","id":"CVE-2010-3035","kev_date_added":"2022-03-25","published":"2010-08-30"},{"cvss_score":6.5,"headline":"Cisco IOS XR Open Port","id":"CVE-2022-20821","kev_date_added":"2022-05-23","published":"2022-05-26"},{"cvss_score":5.9,"headline":"Cisco IOS XR Border Gateway Protocol (BGP) Denial-of-Service","id":"CVE-2009-2055","kev_date_added":"2022-03-25","published":"2009-08-19"},{"cvss_score":9.8,"headline":"Cisco IOS XR Software Security Hardening Release: September 2026","id":"CVE-2026-20274","kev_date_added":null,"published":"2026-09-02"}],"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":"total"},"state":"PUBLISHED","updated":"2024-08-01","vendors":["Cisco"]},"summary":"An unauthenticated adjacent attacker can bypass management plane protection to access the SNMP server on Cisco IOS XR devices.","url":"https://insights.sbomify.com/CVE-2024-20319/"}
