Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-0935 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-2011-0935/ (Markdown: https://insights.sbomify.com/CVE-2011-0935/index.md)","id":"CVE-2011-0935","markdown":"https://insights.sbomify.com/CVE-2011-0935/index.md","name":"CVE-2011-0935","record":{"aliases":["GHSA-w87f-j522-95hp"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IOS","requires_auth":"low_privilege","summary":"Remote attackers can bypass authentication in Cisco IOS PKI by exploiting cached revoked public keys during IKE peer relationships.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios","vendor":"cisco"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"AV:N/AC:L/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-310","name":null}],"description":"The PKI functionality in Cisco IOS 15.0 and 15.1 does not prevent permanent caching of certain public keys, which allows remote attackers to bypass authentication and have unspecified other impact by leveraging an IKE peer relationship in which a key was previously valid but later revoked, aka Bug ID CSCth82164, a different vulnerability than CVE-2010-4685.","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":"Auth bypass in n/a","id":"CVE-2011-0935","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios","products":["cisco:ios"],"type":"auth_bypass","year":"2011"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2011-0939"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2011-0926"},"products":["n/a"],"published":"2011-04-14","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 authentication in Cisco IOS PKI by exploiting cached revoked public keys during IKE peer relationships.","url":"https://insights.sbomify.com/CVE-2011-0935/"}
