A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation. This flaw is strictly related to CVE-2018-13405. A local guest user can create files in the directories shared by virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of the group. This could allow a malicious unprivileged user inside the guest to gain access to resources accessible to the root group, potentially…
The inode_init_owner function in fs/inode.c in the Linux kernel through 4.17.4 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group.
A broken access control vulnerability found in Advan VD-1 firmware version 230 leads to insecure ADB service. An attacker can send a POST request to cgibin/AdbSetting.cgi to enable ADB without any authentication then take the compromised device as a relay or to install mining software.
userfiles/modules/users/controller/controller.php in Microweber before 1.1.20 allows an unauthenticated user to disclose the users database via a /modules/ POST request.
