Missing Firmware Authenticity Checks in Solax Power Pocket WiFi models

The firmware update functionality does not verify the authenticity of the supplied firmware update files. This allows attackers to flash malicious firmware update files on the device. Initial analysis of the firmware update functionality does not show any cryptographic checks (e.g. digital signature checks) on the supplied firmware update files. Furthermore, ESP32 security features such as secure boot are not used.

An issue was discovered in Veritas NetBackup IT Analytics 11 before 11.2.0. The application upgrade process included unsigned files that could be exploited and result in a customer installing unauthentic components. A malicious actor could install rogue Collector executable files (aptare.jar or upgrademanager.zip) on the Portal server, which might then be downloaded and installed on collectors.
