CVE-2023-38301 Vulnerability Analysis & Exploit Intelligence

An issue was discovered in a third-party component related to vendor.gsm.serial, shipped on devices from multiple device manufacturers. Various software builds for the BLU View 2, Boost Mobile Celero 5G, Sharp Rouvo V, Motorola Moto G Pure, Motorola Moto G Power, T-Mobile Revvl 6 Pro 5G, and T-Mobile Revvl V+ 5G devices leak the device serial number to a system property that can be accessed by any local app on the device without any permissions or special privileges. Google restricted third-party apps from directly obtaining non-resettable device identifiers in Android 10 and higher, but in these instances they are leaked by a high-privilege process and can be obtained indirectly. The software build fingerprints for each confirmed vulnerable device are as follows: BLU View 2 (BLU/B131DL/B130DL:11/RP1A.200720.011/1672046950:user/release-keys); Boost Mobile Celero 5G…
