{"id":"GHSA-xvch-r4wf-h8w9","summary":"Improper Certificate Validation in proton-j","details":"The Apache Qpid Proton-J transport includes an optional wrapper layer to perform TLS, enabled by use of the 'transport.ssl(...)' methods. Unless a verification mode was explicitly configured, client and server modes previously defaulted as documented to not verifying a peer certificate, with options to configure this explicitly or select a certificate verification mode with or without hostname verification being performed. The latter hostname verifying mode was not implemented in Apache Qpid Proton-J versions 0.3 to 0.29.0, with attempts to use it resulting in an exception. This left only the option to verify the certificate is trusted, leaving such a client vulnerable to Man In The Middle (MITM) attack. Uses of the Proton-J protocol engine which do not utilise the optional transport TLS wrapper are not impacted, e.g. usage within Qpid JMS. Uses of Proton-J utilising the optional transport TLS wrapper layer that wish to enable hostname verification must be upgraded to version 0.30.0 or later and utilise the VerifyMode#VERIFY_PEER_NAME configuration, which is now the default for client mode usage unless configured otherwise.","aliases":["CVE-2018-17187"],"modified":"2024-03-04T21:49:22.732748Z","published":"2018-11-21T22:22:21Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2020-06-16T22:04:36Z","nvd_published_at":null,"cwe_ids":["CWE-295"],"severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-17187"},{"type":"WEB","url":"https://github.com/apache/qpid-proton-j/commit/0cb8ca03cec42120dcfc434561592d89a89a805e"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-xvch-r4wf-h8w9"},{"type":"WEB","url":"https://issues.apache.org/jira/browse/PROTON-1962"},{"type":"WEB","url":"https://mail-archives.apache.org/mod_mbox/qpid-users/201811.mbox/%3CCAFitrpQSV73Vz7rJYfLJK7gvEymZSCR5ooWUeU8j4jzRydk-eg%40mail.gmail.com%3E"},{"type":"WEB","url":"https://qpid.apache.org/cves/CVE-2018-17187.html"},{"type":"WEB","url":"http://www.securityfocus.com/bid/105935"}],"affected":[{"package":{"name":"org.apache.qpid:proton-j","ecosystem":"Maven","purl":"pkg:maven/org.apache.qpid/proton-j"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.3"},{"fixed":"0.30.0"}]}],"versions":["0.10","0.11.0","0.11.1","0.12.0","0.12.1","0.12.2","0.13.0","0.13.1","0.14.0","0.15.0","0.16.0","0.17.0","0.18.0","0.19.0","0.20.0","0.21.0","0.22.0","0.23.0","0.24.0","0.25.0","0.26.0","0.27.0","0.27.1","0.27.2","0.27.3","0.28.0","0.28.1","0.29.0","0.4","0.5","0.6","0.7","0.8","0.9","0.9.1"],"database_specific":{"last_known_affected_version_range":"\u003c= 0.29.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2018/11/GHSA-xvch-r4wf-h8w9/GHSA-xvch-r4wf-h8w9.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
