PAX A920Pro/A50 devices with PayDroid_8.1.0_Sagittarius_V11.1.50_20230614 or earlier can allow local code execution via parameter injection by bypassing the input validation when flashing a specific partition. The attacker must have physical USB access to the device in order to exploit this vulnerability.
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
