• ZTE Patents: "Method and device for online upgrade" (CN patents often detail the specific architecture).
• Technologies: ZTE often brands its update technologies under names like "ZTE Share" or specific marketing terms for their UI updates (e.g., MyOS updates).
• ZTE FOTA (Firmware Over The Air): This is the technical standard term used in their engineering documentation.

• Description: The framework has been found to lack proper integrity verification for software update packages. In specific versions, the mechanism responsible for verifying the digital signature of an OTA package is either insufficient or can be bypassed.
• Impact: An attacker with local access or Man-in-the-Middle (MitM) capabilities on the network could replace a legitimate update package with a malicious one. The device would then install the malicious payload, leading to Privilege Escalation and Arbitrary Code Execution.
• Root Cause: Failure to cryptographically validate the certificate chain or allowing the installation of packages with broken signatures.
