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-2012-4643 in the wild and no public exploit code.\n\nAffected product: Cisco 5500 Series Adaptive Security Appliance. 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-2012-4643/ (Markdown: https://insights.sbomify.com/CVE-2012-4643/index.md)","id":"CVE-2012-4643","markdown":"https://insights.sbomify.com/CVE-2012-4643/index.md","name":"CVE-2012-4643","record":{"aliases":["GHSA-q56j-8xm2-393w"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco ASA firewall","requires_auth":"none","summary":"Remote attackers can cause a denial of service and device reload on Cisco ASA devices by sending crafted IPv4 DHCP packets.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"5500_series_adaptive_security_appliance","vendor":"cisco"},{"product":"adaptive_security_appliance_software","vendor":"cisco"},{"product":"catalyst_6500","vendor":"cisco"},{"product":"catalyst_6503-e","vendor":"cisco"},{"product":"catalyst_6504-e","vendor":"cisco"},{"product":"catalyst_6506-e","vendor":"cisco"},{"product":"catalyst_6509-e","vendor":"cisco"},{"product":"catalyst_6509-neb-a","vendor":"cisco"},{"product":"catalyst_6509-v-e","vendor":"cisco"},{"product":"catalyst_6513","vendor":"cisco"},{"product":"catalyst_6513-e","vendor":"cisco"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"The DHCP server on Cisco Adaptive Security Appliances (ASA) 5500 series devices, and the ASA Services Module (ASASM) in Cisco Catalyst 6500 series devices, with software 7.0 before 7.2(5.8), 7.1 before 7.2(5.8), 7.2 before 7.2(5.8), 8.0 before 8.0(5.28), 8.1 before 8.1(2.56), 8.2 before 8.2(5.27), 8.3 before 8.3(2.31), 8.4 before 8.4(3.10), 8.5 before 8.5(1.9), and 8.6 before 8.6(1.5) does not properly allocate memory for DHCP packets, which allows remote attackers to cause a denial of service (device reload) via a series of crafted IPv4 packets, aka Bug ID CSCtw84068.","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":"Denial of service in n/a","id":"CVE-2012-4643","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:5500_series_adaptive_security_appliance","products":["cisco:5500_series_adaptive_security_appliance","cisco:adaptive_security_appliance_software"],"type":"denial_of_service","year":"2012"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2012-4651"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2012-4638"},"products":["n/a"],"published":"2012-10-29","related":[{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2012-0358","kev_date_added":null,"published":"2012-03-15"},{"cvss_score":9,"headline":"Memory corruption in n/a","id":"CVE-2012-4661","kev_date_added":null,"published":"2012-10-29"},{"cvss_score":9,"headline":"Auth bypass in n/a","id":"CVE-2010-4675","kev_date_added":null,"published":"2011-01-07"},{"cvss_score":9,"headline":"Security feature bypass in n/a","id":"CVE-2010-4680","kev_date_added":null,"published":"2011-01-07"},{"cvss_score":7.9,"headline":"Auth bypass in n/a","id":"CVE-2011-3298","kev_date_added":null,"published":"2011-10-06"},{"cvss_score":7.9,"headline":"Memory corruption in n/a","id":"CVE-2011-0379","kev_date_added":null,"published":"2011-02-25"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2013-1149","kev_date_added":null,"published":"2013-04-11"}],"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 cause a denial of service and device reload on Cisco ASA devices by sending crafted IPv4 DHCP packets.","url":"https://insights.sbomify.com/CVE-2012-4643/"}
