CVE-2024-23963
HIGHCVSS Vector
CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Lifecycle Timeline
2Description
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Alpine Halo9 devices. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability. The specific flaw exists within the PBAP_DecodeVCARD function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root.
Analysis
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Alpine Halo9 devices. Rated high severity (CVSS 8.0), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Technical Context
This vulnerability is classified as Code Injection (CWE-94), which allows attackers to inject and execute arbitrary code within the application.
