{"id":"CVE-2023-41081","summary":"Apache Tomcat Connectors: Unexpected use of first declared worker in mod_jk for unmapped request","details":"Important: Authentication Bypass CVE-2023-41081\n\nThe mod_jk component of Apache Tomcat Connectors in some circumstances, such as when a configuration included \"JkOptions +ForwardDirectories\" but the configuration did not       provide explicit mounts for all possible proxied requests, mod_jk would       use an implicit mapping and map the request to the first defined worker. Such an implicit mapping could result in the unintended exposure of the status worker and/or bypass security constraints configured in httpd. As of JK 1.2.49, the implicit mapping functionality has been removed and all mappings must now be via explicit configuration. Only mod_jk is affected by this issue. The ISAPI redirector is not affected.\n\nThis issue affects Apache Tomcat Connectors (mod_jk only): from 1.2.0 through 1.2.48.\n\nUsers are recommended to upgrade to version 1.2.49, which fixes the issue.\n\nHistory\n2023-09-13 Original advisory\n\n2023-09-28 Updated summary\n\n","modified":"2026-05-01T04:20:33.794940Z","published":"2023-09-13T09:30:05.584Z","related":["ALSA-2024:2387","SUSE-SU-2024:1198-1","SUSE-SU-2025:0102-1"],"database_specific":{"unresolved_ranges":[{"extracted_events":[{"introduced":"1.2.0"},{"last_affected":"1.2.48"}],"source":"AFFECTED_FIELD"},{"extracted_events":[{"introduced":"1.2.0"},{"fixed":"1.2.48"}],"source":"DESCRIPTION"}],"cna_assigner":"apache","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/41xxx/CVE-2023-41081.json"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2023/09/28/7"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/09/msg00027.html"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2023/09/13/2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/41xxx/CVE-2023-41081.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/rd1r26w7271jyqgzr4492tooyt583d8b"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-41081"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/tomcat-connectors","events":[{"introduced":"57f0a5b2de30a4000314a8e7b20a778ff7f1190e"},{"fixed":"3ad622409ae3335df9f353bef8ebc4d72a70fd6d"}],"database_specific":{"cpe":"cpe:2.3:a:apache:tomcat_connectors:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"1.2.0"},{"fixed":"1.2.49"}],"source":"CPE_FIELD"}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-41081.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
