Alpine iLX-F511 prh_sdp_service_search_decode Stack-based Buffer Overflow Remote Code Execution Vulnerability

Impact

Alpine iLX-F511 version 7.0.000 has a stack-based buffer overflow weakness in the prh_sdp_service_search_decode function, allowing network-adjacent attackers with paired Bluetooth device access to potentially execute arbitrary code. The issue is due to a lack of proper validation of user-supplied data length. An attacker must first pair a malicious Bluetooth device with the target system.

Original source description

Alpine iLX-F511 prh_sdp_service_search_decode Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Alpine iLX-F511 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 prh_sdp_service_search_decode 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. Was ZDI-CAN-29069.
