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-2016-10027 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.igniterealtime.smack:smack-core (Maven): affected all versions; fixed in 4.1.9\n- org.igniterealtime.smack:smack-core (Maven): affected all versions; fixed in 4.1.9\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-2016-10027/ (Markdown: https://insights.sbomify.com/CVE-2016-10027/index.md)","id":"CVE-2016-10027","markdown":"https://insights.sbomify.com/CVE-2016-10027/index.md","name":"CVE-2016-10027","record":{"aliases":["GHSA-66pq-hqv5-228g"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"XMPP Java library","requires_auth":"none","summary":"Man-in-the-middle attackers can bypass TLS protections and force cleartext authentication in Smack XMPP library when SecurityMode.required is set.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"smack","vendor":"igniterealtime"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"Race condition in the XMPP library in Smack before 4.1.9, when the SecurityMode.required TLS setting has been set, allows man-in-the-middle attackers to bypass TLS protections and trigger use of cleartext for client authentication by stripping the \"starttls\" feature from a server response.","ecosystems":["Maven"],"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":"Smack allows the bypass of TLS protections","id":"CVE-2016-10027","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"race_condition","year":"2016"},"n_packages":2,"n_references":7,"next":{"headline":"Denial of service in n/a","id":"CVE-2016-10028"},"packages":[{"ecosystem":"Maven","fixed":["4.1.9"],"introduced":["0"],"last_affected":[],"package":"org.igniterealtime.smack:smack-core","purl":null,"source":"GHSA-66pq-hqv5-228g"},{"ecosystem":"Maven","fixed":["4.1.9"],"introduced":["0"],"last_affected":[],"package":"org.igniterealtime.smack:smack-core","purl":"pkg:maven/org.igniterealtime.smack/smack-core","source":"GHSA-66pq-hqv5-228g"}],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2016-10026"},"products":["n/a"],"published":"2017-01-12","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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 bypass TLS protections and force cleartext authentication in Smack XMPP library when SecurityMode.required is set.","url":"https://insights.sbomify.com/CVE-2016-10027/"}
