A vulnerability in the web-based GUI of Cisco Prime Home could allow an unauthenticated, remote attacker to bypass authentication and execute actions with administrator privileges. The vulnerability is due to a processing error in the role-based access control (RBAC) of URLs. An attacker could exploit this vulnerability by sending API commands via HTTP to a particular URL without prior authentication. An exploit could allow the attacker to perform any actions in Cisco Prime Home with administrator privileges. This vulnerability affects Cisco Prime Home versions from 6.3.0.0 to the first fixed release 6.5.0.1. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Cisco Bug IDs: CSCvb49837.Show less

An issue was discovered in ABOOT in OnePlus 3 and 3T OxygenOS before 4.0.2. The attacker can reboot the device into the fastboot mode, which could be done without any authentication. A physical attacker can press the "Volume Up" button during device boot, where an attacker with ADB access can issue the adb reboot bootloader command. Then, the attacker can put the platform's SELinux in permissive mode, which severely weakens it, by issuing: fastboot oem selinux permissive.Show less
