DescriptionAttendo (formerly Petpooja Payroll) Admin Android application version 3.0.13 and earlier contains a hard-coded credentials vulnerability that allows attackers to extract production MQTT broker credentials by decompiling the APK's bundled Flutter configuration assets such as production.json and device-command configuration files. Attackers can use the recovered credentials to authenticate to the production MQTT broker over TCP 1883, access messaging topics containing employee attendance records, personal identifiers, Base64-encoded photographs, device telemetry, and authentication material, and publish messages to those topics, resulting in exposure of sensitive data and potential unauthorized message injection.
