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-2015-6291 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-2015-6291/ (Markdown: https://insights.sbomify.com/CVE-2015-6291/index.md)","id":"CVE-2015-6291","markdown":"https://insights.sbomify.com/CVE-2015-6291/index.md","name":"CVE-2015-6291","record":{"aliases":["GHSA-xmvm-48fw-3ghc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Email Security Appliance","requires_auth":"none","summary":"Remote attackers can cause denial of service via memory consumption by sending crafted email attachments to Cisco Email Security Appliances.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"email_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-20","name":"Improper Input Validation"}],"description":"Cisco AsyncOS before 8.5.7-043, 9.x before 9.1.1-023, and 9.5.x and 9.6.x before 9.6.0-046 on Email Security Appliance (ESA) devices mishandles malformed fields during body-contains, attachment-contains, every-attachment-contains, attachment-binary-contains, dictionary-match, and attachment-dictionary-match filtering, which allows remote attackers to cause a denial of service (memory consumption) via a crafted attachment in an e-mail message, aka Bug ID CSCuv47151.","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-2015-6291","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:email_security_appliance","products":["cisco:email_security_appliance"],"type":"denial_of_service","year":"2015"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2015-6292"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2015-6290"},"products":["n/a"],"published":"2015-11-06","related":[{"cvss_score":9.8,"headline":"Cisco Email Security Appliance and Cisco Secure Email and Web Manager External Authentication Bypass Vulnerability","id":"CVE-2022-20798","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":7.7,"headline":"Cisco Email Security Appliance and Cisco Secure Email and Web Manager Information Disclosure Vulnerability","id":"CVE-2022-20664","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":7.5,"headline":"Denial of service in Cisco Secure Email","id":"CVE-2022-20960","kev_date_added":null,"published":"2022-11-03"},{"cvss_score":7.5,"headline":"Security feature bypass in Email Security Appliance (ESA)","id":"CVE-2018-0419","kev_date_added":null,"published":"2018-08-15"},{"cvss_score":7.5,"headline":"Security feature bypass in Cisco AsyncOS through WSA10.0.0-000","id":"CVE-2016-1480","kev_date_added":null,"published":"2016-10-28"},{"cvss_score":7.5,"headline":"Denial of service in Cisco AsyncOS through 9.7.0-125","id":"CVE-2016-1481","kev_date_added":null,"published":"2016-10-28"}],"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 memory consumption by sending crafted email attachments to Cisco Email Security Appliances.","url":"https://insights.sbomify.com/CVE-2015-6291/"}
