{"id":"UBUNTU-CVE-2023-30801","details":"All versions of the qBittorrent client through 4.5.5 use default credentials when the web user interface is enabled. The administrator is not forced to change the default credentials. As of 4.5.5, this issue has not been fixed. A remote attacker can use the default credentials to authenticate and execute arbitrary operating system commands using the \"external program\" feature in the web user interface. This was reportedly exploited in the wild in March 2023.","modified":"2026-05-20T16:13:35.450066382Z","published":"2023-10-10T14:15:00Z","upstream":["CVE-2023-30801"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-30801"},{"type":"REPORT","url":"https://vulncheck.com/advisories/qbittorrent-default-creds"},{"type":"REPORT","url":"https://github.com/qbittorrent/qBittorrent/issues/18731"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-30801"}],"affected":[{"package":{"name":"qbittorrent","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/qbittorrent?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.3-2","3.2.5-1","3.3.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"qbittorrent","binary_version":"3.3.1-1"},{"binary_name":"qbittorrent-nox","binary_version":"3.3.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30801.json"}},{"package":{"name":"qbittorrent","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/qbittorrent?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.7-3","3.3.15-1","4.0.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"qbittorrent","binary_version":"4.0.3-1"},{"binary_name":"qbittorrent-nox","binary_version":"4.0.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30801.json"}},{"package":{"name":"qbittorrent","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/qbittorrent?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.1.7-1","4.1.7-1ubuntu2","4.1.7-1ubuntu3"],"ecosystem_specific":{"binaries":[{"binary_name":"qbittorrent","binary_version":"4.1.7-1ubuntu3"},{"binary_name":"qbittorrent-nox","binary_version":"4.1.7-1ubuntu3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30801.json"}},{"package":{"name":"qbittorrent","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/qbittorrent?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.2.5-0.1ubuntu1","4.2.5-0.1ubuntu2","4.3.9-1","4.3.9-2","4.4.0-1","4.4.0-2","4.4.1-2"],"ecosystem_specific":{"binaries":[{"binary_name":"qbittorrent","binary_version":"4.4.1-2"},{"binary_name":"qbittorrent-nox","binary_version":"4.4.1-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30801.json"}},{"package":{"name":"qbittorrent","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/qbittorrent?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.5.4-1","4.6.0-1","4.6.1-1","4.6.1-2","4.6.2-1","4.6.2-2","4.6.2-3","4.6.3-1","4.6.3-1build1","4.6.3-1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"qbittorrent","binary_version":"4.6.3-1build2"},{"binary_name":"qbittorrent-nox","binary_version":"4.6.3-1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30801.json"}},{"package":{"name":"qbittorrent","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/qbittorrent?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.4-1","5.0.5-1","5.1.0-1","5.1.0-2","5.1.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"qbittorrent","binary_version":"5.1.2-1"},{"binary_name":"qbittorrent-nox","binary_version":"5.1.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30801.json"}},{"package":{"name":"qbittorrent","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/qbittorrent?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.1.2-1","5.1.3-1","5.1.4-dmo1"],"ecosystem_specific":{"binaries":[{"binary_name":"qbittorrent","binary_version":"5.1.4-dmo1"},{"binary_name":"qbittorrent-nox","binary_version":"5.1.4-dmo1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-30801.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:H/A:H"},{"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"}]}
