{"id":"UBUNTU-CVE-2019-16942","details":"A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the commons-dbcp (1.4) jar in the classpath, and an attacker can find an RMI service endpoint to access, it is possible to make the service execute a malicious payload. This issue exists because of org.apache.commons.dbcp.datasources.SharedPoolDataSource and org.apache.commons.dbcp.datasources.PerUserPoolDataSource mishandling.","modified":"2026-01-30T02:48:26.490756Z","published":"2019-10-01T17:15:00Z","related":["USN-4813-1"],"upstream":["CVE-2019-16942"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-16942"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/issues/2478"},{"type":"REPORT","url":"https://issues.apache.org/jira/browse/GEODE-7255"},{"type":"REPORT","url":"https://medium.com/@cowtowncoder/on-jackson-cves-dont-panic-here-is-what-you-need-to-know-54cd0d6e8062"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4813-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-16942"}],"affected":[{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/jackson-databind@2.2.2-1ubuntu0.1~esm1?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.2-1","2.2.2-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.2.2-1ubuntu0.1~esm1","binary_name":"libjackson2-databind-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-16942.json"}},{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/jackson-databind@2.4.2-3ubuntu0.1~esm2?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.2-3ubuntu0.1~esm2"}]}],"versions":["2.4.2-2","2.4.2-3","2.4.2-3ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.4.2-3ubuntu0.1~esm2","binary_name":"libjackson2-databind-java"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-16942.json"}},{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/jackson-databind@2.9.8-1~18.04?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.8.6-1","2.9.1-1","2.9.4-1","2.9.5-1","2.9.8-1~18.04"],"ecosystem_specific":{"binaries":[{"binary_version":"2.9.8-1~18.04","binary_name":"libjackson2-databind-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-16942.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
