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-2013-5537 in the wild and no public exploit code.\n\nAffected product: Cisco Web 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-2013-5537/ (Markdown: https://insights.sbomify.com/CVE-2013-5537/index.md)","id":"CVE-2013-5537","markdown":"https://insights.sbomify.com/CVE-2013-5537/index.md","name":"CVE-2013-5537","record":{"aliases":["GHSA-pmxm-xgr9-jvfw"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Security Appliance","requires_auth":"none","summary":"Remote attackers can cause a denial of service on Cisco security appliances by exhausting session resources via multiple TCP connections.","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_firmware","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-20","name":"Improper Input Validation"}],"description":"The web framework on Cisco Web Security Appliance (WSA), Email Security Appliance (ESA), and Content Security Management Appliance (SMA) devices does not properly manage the state of HTTP and HTTPS sessions, which allows remote attackers to cause a denial of service (management GUI outage) via multiple TCP connections, aka Bug IDs CSCuj59411, CSCuf89818, and CSCuh05635.","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-2013-5537","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:web_security_appliance","products":["cisco:web_security_appliance"],"type":"denial_of_service","year":"2013"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in n/a","id":"CVE-2013-5538"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2013-5536"},"products":["n/a"],"published":"2013-10-24","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-2015-6321","kev_date_added":null,"published":"2015-11-06"},{"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":"2024-09-16","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service on Cisco security appliances by exhausting session resources via multiple TCP connections.","url":"https://insights.sbomify.com/CVE-2013-5537/"}
