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-2015-6321 in the wild and no public exploit code.\n\nAffected product: Cisco Email 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-2015-6321/ (Markdown: https://insights.sbomify.com/CVE-2015-6321/index.md)","id":"CVE-2015-6321","markdown":"https://insights.sbomify.com/CVE-2015-6321/index.md","name":"CVE-2015-6321","record":{"aliases":["GHSA-rmcx-cqh3-x8cj"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Security Appliance","requires_auth":"none","summary":"Remote attackers can cause denial of service via TCP packet floods on Cisco Email, Content, and Web Security Appliances.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"content_security_management_appliance","vendor":"cisco"},{"product":"email_security_appliance","vendor":"cisco"},{"product":"web_security_appliance","vendor":"cisco"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"Cisco AsyncOS before 8.5.7-042, 9.x before 9.1.0-032, 9.1.x before 9.1.1-023, and 9.5.x and 9.6.x before 9.6.0-042 on Email Security Appliance (ESA) devices; before 9.1.0-032, 9.1.1 before 9.1.1-005, and 9.5.x before 9.5.0-025 on Content Security Management Appliance (SMA) devices; and before 7.7.0-725 and 8.x before 8.0.8-113 on Web Security Appliance (WSA) devices allows remote attackers to cause a denial of service (memory consumption) via a flood of TCP packets, aka Bug IDs CSCus79774, CSCus79777, and CSCzv95795.","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-2015-6321","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:email_security_appliance","products":["cisco:email_security_appliance","cisco:web_security_appliance"],"type":"denial_of_service","year":"2015"},"n_packages":0,"n_references":3,"next":{"headline":"Path traversal in n/a","id":"CVE-2015-6322"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2015-6320"},"products":["n/a"],"published":"2015-11-06","related":[{"cvss_score":8.5,"headline":"File upload in n/a","id":"CVE-2014-2119","kev_date_added":null,"published":"2014-03-20"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2013-5537","kev_date_added":null,"published":"2013-10-24"},{"cvss_score":7.5,"headline":"Weak cryptography in n/a","id":"CVE-2016-2183","kev_date_added":null,"published":"2016-09-01"},{"cvss_score":6.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2013-3395","kev_date_added":null,"published":"2013-07-02"},{"cvss_score":6.7,"headline":"Cisco Content Security Management Appliance Privilege Escalation Vulnerability","id":"CVE-2021-1447","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":6.5,"headline":"Missing authorization in Cisco Email Security Appliance and Cisco Content Security Management Appliance","id":"CVE-2018-0140","kev_date_added":null,"published":"2018-02-08"}],"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 denial of service via TCP packet floods on Cisco Email, Content, and Web Security Appliances.","url":"https://insights.sbomify.com/CVE-2015-6321/"}
