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-2018-1067 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jboss.eap:wildfly-undertow (Maven): affected all versions; fixed in 7.1.2.GA\n- org.jboss.eap:wildfly-undertow (Maven): affected all versions; fixed in 7.1.2.GA\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-2018-1067/ (Markdown: https://insights.sbomify.com/CVE-2018-1067/index.md)","id":"CVE-2018-1067","markdown":"https://insights.sbomify.com/CVE-2018-1067/index.md","name":"CVE-2018-1067","record":{"aliases":["DEBIAN-CVE-2018-1067","GHSA-47mp-rq2x-wjf2","UBUNTU-CVE-2018-1067"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Undertow web server","requires_auth":"none","summary":"Attackers can inject arbitrary HTTP headers or split responses in Undertow due to insufficient input sanitization, potentially bypassing security controls.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"jboss_enterprise_application_platform","vendor":"redhat"},{"product":"undertow","vendor":"redhat"},{"product":"virtualization_host","vendor":"redhat"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-113","name":"Improper Neutralization of CRLF Sequences in HTTP Headers"}],"description":"In Undertow before versions 7.1.2.CR1, 7.1.2.GA it was found that the fix for CVE-2016-4993 was incomplete and Undertow web server is vulnerable to the injection of arbitrary HTTP headers, and also response splitting, due to insufficient sanitization and validation of user input before the input is used as part of an HTTP header value.","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 HTTP Headers in Undertow","id":"CVE-2018-1067","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"redhat:jboss_enterprise_application_platform","products":["redhat:jboss_enterprise_application_platform","redhat:virtualization_host"],"type":"other","year":"2018"},"n_packages":2,"n_references":7,"next":{"headline":"Memory corruption in Linux Kernel","id":"CVE-2018-1068"},"packages":[{"ecosystem":"Maven","fixed":["7.1.2.GA"],"introduced":["0"],"last_affected":[],"package":"org.jboss.eap:wildfly-undertow","purl":null,"source":"GHSA-47mp-rq2x-wjf2"},{"ecosystem":"Maven","fixed":["7.1.2.GA"],"introduced":["0"],"last_affected":[],"package":"org.jboss.eap:wildfly-undertow","purl":"pkg:maven/org.jboss.eap/wildfly-undertow","source":"GHSA-47mp-rq2x-wjf2"}],"prev":{"headline":"Null dereference in Linux kernel 4.11","id":"CVE-2018-1066"},"products":["undertow"],"published":"2018-05-21","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":"2024-08-05","vendors":["[UNKNOWN]"]},"summary":"Attackers can inject arbitrary HTTP headers or split responses in Undertow due to insufficient input sanitization, potentially bypassing security controls.","url":"https://insights.sbomify.com/CVE-2018-1067/"}
