This connection attempt fails, but it contains in the header the current session of the user. This session could then be stolen by a man-in-the-middle.","modified":"2026-01-20T16:56:04.733026Z","published":"2018-11-22T19:29:00Z","upstream":["CVE-2018-19443"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-19443"},{"type":"REPORT","url":"https://discuss.tryton.org/t/security-release-for-issue7792/830"},{"type":"REPORT","url":"https://bugs.tryton.org/issue7792"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-19443"}],"affected":[{"package":{"name":"tryton-client","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/tryton-client@3.8.4-1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6.2-1","3.6.3-1","3.8.2-1","3.8.3-1","3.8.4-1"],"ecosystem_specific":{"binaries":[{"binary_name":"tryton-client","binary_version":"3.8.4-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-19443.json"}},{"package":{"name":"tryton-client","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/tryton-client@4.6.5-1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.4.1-2","4.4.2-1","4.6.0-1","4.6.1-1","4.6.2-1","4.6.5-1"],"ecosystem_specific":{"binaries":[{"binary_name":"tryton-client","binary_version":"4.6.5-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-19443.json"}},{"package":{"name":"tryton-client","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/tryton-client@5.0.17-1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.12-1","5.0.15-1","5.0.17-1"],"ecosystem_specific":{"binaries":[{"binary_name":"tryton-client","binary_version":"5.0.17-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-19443.json"}},{"package":{"name":"tryton-client","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/tryton-client@6.0.10-1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.33-1","6.0.8-1","6.0.8-2","6.0.10-1"],"ecosystem_specific":{"binaries":[{"binary_name":"tryton-client","binary_version":"6.0.10-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-19443.json"}},{"package":{"name":"tryton-client","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/tryton-client@6.0.34-1?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.0.28-1","6.0.29-1","6.0.34-1"],"ecosystem_specific":{"binaries":[{"binary_name":"tryton-client","binary_version":"6.0.34-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-19443.json"}},{"package":{"name":"tryton-client","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/tryton-client@7.0.24-1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.0.20-1","7.0.24-1"],"ecosystem_specific":{"binaries":[{"binary_name":"tryton-client","binary_version":"7.0.24-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-19443.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
