A number of zero-day vulnerabilities that were addressed last year were exploited by commercial spyware vendors to target Android and iOS devices, Google's Threat Analysis Group (TAG) has revealed. The two distinct campaigns were both limited and highly targeted, taking advantage of the patch gap between the release of a fix and when it was actually deployed on the targeted devices. "These

An issue was discovered in Veritas Backup Exec before 21.2. It supports multiple authentication schemes: SHA authentication is one of these. This authentication scheme is no longer used in current versions of the product, but hadn't yet been disabled. An attacker could remotely exploit this scheme to gain unauthorized access to an Agent and execute privileged commands.

An issue was discovered in Veritas Backup Exec before 21.2. The communication between a client and an Agent requires successful authentication, which is typically completed over a secure TLS communication. However, due to a vulnerability in the SHA Authentication scheme, an attacker is able to gain unauthorized access and complete the authentication process. Subsequently, the client can execute data management protocol commands on the authenticated connection. The attacker could use one of these commands to execute an arbitrary command on the system using system privileges.
