An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-2395 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-2011-2395/ (Markdown: https://insights.sbomify.com/CVE-2011-2395/index.md)","id":"CVE-2011-2395","markdown":"https://insights.sbomify.com/CVE-2011-2395/index.md","name":"CVE-2011-2395","record":{"aliases":["GHSA-mg4g-9536-v7mv"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IOS switch","requires_auth":"none","summary":"Remote attackers can bypass Router Advertisement Guarding on Cisco IOS switches by sending fragmented IPv6 packets, allowing unauthorized network configuration changes.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ios","vendor":"cisco"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-16","name":null}],"description":"The Neighbor Discovery (ND) protocol implementation in Cisco IOS on unspecified switches allows remote attackers to bypass the Router Advertisement Guarding functionality via a fragmented IPv6 packet in which the Router Advertisement (RA) message is contained in the second fragment, as demonstrated by (1) a packet in which the first fragment contains a long Destination Options extension header or (2) a packet in which the first fragment contains an ICMPv6 Echo Request message.","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 n/a","id":"CVE-2011-2395","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios","products":["cisco:ios"],"type":"security_feature_bypass","year":"2011"},"n_packages":0,"n_references":3,"next":{"headline":"Command injection in n/a","id":"CVE-2011-2397"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2011-2393"},"products":["n/a"],"published":"2011-06-07","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can bypass Router Advertisement Guarding on Cisco IOS switches by sending fragmented IPv6 packets, allowing unauthorized network configuration changes.","url":"https://insights.sbomify.com/CVE-2011-2395/"}
