A vulnerability, which was classified as critical, was found in Apple iOS 7/8/9 (Smartphone Operating System). Affected is an unknown function of the component Bluetooth Stack. The manipulation as part of a Audio Command leads to a memory corruption vulnerability (BlueBorne). CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
In Apple iOS 7 through 9, due to a BlueBorne flaw in the implementation of LEAP (Low Energy Audio Protocol), a large audio command can be sent to a targeted device and lead to a heap overflow with attacker-controlled data. Since the audio commands sent via LEAP are not properly validated, an attacker can use this overflow to gain full control of the device through the relatively high privileges of the Bluetooth stack in iOS. The attack bypasses Bluetooth access control; however, the default "Bluetooth On" value must be present in Settings.
The bug was discovered 09/12/2017. The weakness was presented 09/12/2017 (Website). The advisory is shared for download at securityfocus.com. This vulnerability is traded as CVE-2017-14315 since 09/12/2017. The attack needs to approached within the local network. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 01/11/2021). It is expected to see the exploit prices for this product increasing in the near future.
