Five other CVEs were also disclosed in Backup & Replication, including several that allow users who have been assigned low-privileged roles to alter multi-factor authentication (MFA) settings, achieve remote code execution as a service account, and extract sensitive data (e.g., credentials, passwords). Other vulnerabilities in the bulletin affect additional Ve...
