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-2013-1740 in the wild and no public exploit code.\n\nAffected product: Mozilla Network Security Services. 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-2013-1740/ (Markdown: https://insights.sbomify.com/CVE-2013-1740/index.md)","id":"CVE-2013-1740","markdown":"https://insights.sbomify.com/CVE-2013-1740/index.md","name":"CVE-2013-1740","record":{"aliases":["DEBIAN-CVE-2013-1740","GHSA-26rr-whcg-5f4g","MGASA-2014-0024"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"NSS SSL library","requires_auth":"none","summary":"Man-in-the-middle attackers can spoof SSL servers by exploiting TLS False Start in NSS, bypassing certificate validation.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mozilla","cpe":[{"product":"network_security_services","vendor":"mozilla"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-310","name":null}],"description":"The ssl_Do1stHandshake function in sslsecur.c in libssl in Mozilla Network Security Services (NSS) before 3.15.4, when the TLS False Start feature is enabled, allows man-in-the-middle attackers to spoof SSL servers by using an arbitrary X.509 certificate during certain handshake traffic.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Security feature bypass in n/a","id":"CVE-2013-1740","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mozilla:network_security_services","products":["mozilla:network_security_services"],"type":"security_feature_bypass","year":"2013"},"n_packages":0,"n_references":17,"next":{"headline":"Integer overflow in n/a","id":"CVE-2013-1741"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2013-1739"},"products":["n/a"],"published":"2014-01-18","related":[{"cvss_score":9.8,"headline":"Memory corruption in NSS","id":"CVE-2019-17006","kev_date_added":null,"published":"2020-10-22"},{"cvss_score":9.8,"headline":"Memory corruption in Firefox","id":"CVE-2017-5461","kev_date_added":null,"published":"2017-05-11"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2009-2404","kev_date_added":null,"published":"2009-08-03"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2017-11695","kev_date_added":null,"published":"2017-12-27"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2017-11696","kev_date_added":null,"published":"2017-12-27"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2017-11697","kev_date_added":null,"published":"2017-12-27"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2017-11698","kev_date_added":null,"published":"2017-12-27"}],"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":"Man-in-the-middle attackers can spoof SSL servers by exploiting TLS False Start in NSS, bypassing certificate validation.","url":"https://insights.sbomify.com/CVE-2013-1740/"}
