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-2013-3436 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-2013-3436/ (Markdown: https://insights.sbomify.com/CVE-2013-3436/index.md)","id":"CVE-2013-3436","markdown":"https://insights.sbomify.com/CVE-2013-3436/index.md","name":"CVE-2013-3436","record":{"aliases":["GHSA-6c9w-3vp8-m2hh"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IOS GET VPN","requires_auth":"none","summary":"Remote attackers can bypass GET VPN encryption policies on Cisco IOS devices by exploiting improper GDOI traffic flow handling on UDP port 848.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios","vendor":"cisco"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:N/A:N","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"The default configuration of the Group Encrypted Transport VPN (GET VPN) feature on Cisco IOS uses an improper mechanism for enabling Group Domain of Interpretation (GDOI) traffic flow, which allows remote attackers to bypass the encryption policy via certain uses of UDP port 848, aka Bug ID CSCui07698.","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-2013-3436","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios","products":["cisco:ios"],"type":"security_feature_bypass","year":"2013"},"n_packages":0,"n_references":6,"next":{"headline":"SQL injection in n/a","id":"CVE-2013-3437"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2013-3435"},"products":["n/a"],"published":"2013-07-18","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 GET VPN encryption policies on Cisco IOS devices by exploiting improper GDOI traffic flow handling on UDP port 848.","url":"https://insights.sbomify.com/CVE-2013-3436/"}
