An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-4993 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.wildfly:wildfly-undertow (Maven): affected from 10.0.0.Final; fixed in 11.0.0.Final\n- org.wildfly:wildfly-undertow (Maven): affected from 10.0.0.Final; fixed in 11.0.0.Final\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-2016-4993/ (Markdown: https://insights.sbomify.com/CVE-2016-4993/index.md)","id":"CVE-2016-4993","markdown":"https://insights.sbomify.com/CVE-2016-4993/index.md","name":"CVE-2016-4993","record":{"aliases":["CVE-2016-6339","DEBIAN-CVE-2016-4993","GHSA-qcqr-hcjq-whfq","UBUNTU-CVE-2016-4993"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WildFly Undertow server","requires_auth":"none","summary":"Remote attackers can inject HTTP headers and split responses in WildFly Undertow, potentially manipulating client interactions.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"jboss_enterprise_application_platform","vendor":"redhat"},{"product":"jboss_wildfly_application_server","vendor":"redhat"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"},{"id":"CWE-113","name":"Improper Neutralization of CRLF Sequences in HTTP Headers"}],"description":"CRLF injection vulnerability in the Undertow web server in WildFly 10.0.0, as used in Red Hat JBoss Enterprise Application Platform (EAP) 7.x before 7.0.2, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.","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":"Improper Neutralization of CRLF Sequences in Wildfly Undertow","id":"CVE-2016-4993","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"redhat:jboss_enterprise_application_platform","products":["redhat:jboss_enterprise_application_platform"],"type":"other","year":"2016"},"n_packages":2,"n_references":11,"next":{"headline":"Use after free in n/a","id":"CVE-2016-4994"},"packages":[{"ecosystem":"Maven","fixed":["11.0.0.Final"],"introduced":["10.0.0.Final"],"last_affected":[],"package":"org.wildfly:wildfly-undertow","purl":null,"source":"GHSA-qcqr-hcjq-whfq"},{"ecosystem":"Maven","fixed":["11.0.0.Final"],"introduced":["10.0.0.Final"],"last_affected":[],"package":"org.wildfly:wildfly-undertow","purl":"pkg:maven/org.wildfly/wildfly-undertow","source":"GHSA-qcqr-hcjq-whfq"}],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2016-4992"},"products":["n/a"],"published":"2016-09-26","related":[{"cvss_score":9.8,"headline":"Red Hat JBoss Application Server Remote Code Execution","id":"CVE-2017-12149","kev_date_added":"2021-12-10","published":"2017-10-04"},{"cvss_score":5.9,"headline":"Red Hat JBoss Information Disclosure","id":"CVE-2010-1428","kev_date_added":"2022-05-25","published":"2010-04-28"},{"cvss_score":3.7,"headline":"Red Hat JBoss Authentication Bypass","id":"CVE-2010-0738","kev_date_added":"2022-05-25","published":"2010-04-28"},{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2016-3690","kev_date_added":null,"published":"2017-06-08"},{"cvss_score":9.8,"headline":"Deserialization in JBoss","id":"CVE-2017-7504","kev_date_added":null,"published":"2017-05-19"},{"cvss_score":9.8,"headline":"XML external entity in JBoss Enterprise Application Platform","id":"CVE-2017-7503","kev_date_added":null,"published":"2017-05-18"},{"cvss_score":9.8,"headline":"Improper Input Validation in JGroups","id":"CVE-2016-2141","kev_date_added":null,"published":"2016-06-30"}],"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":"Remote attackers can inject HTTP headers and split responses in WildFly Undertow, potentially manipulating client interactions.","url":"https://insights.sbomify.com/CVE-2016-4993/"}
