CVE-2024-49714 is a vulnerability identified in Google Android operating system versions 13 and 14, specifically within the Bluetooth AVRCP (Audio/Video Remote Control Profile) implementation. The flaw exists in the avrc_vendor_msg function of the avrc_opt.cc source file, where a heap buffer overflow occurs due to an out-of-bounds write. This vulnerability is categorized as CWE-122, indicating a heap-based buffer overflow that can corrupt memory. The overflow can be triggered by a paired device communicating with the vulnerable Android device, enabling an attacker to escalate privileges on the device without needing additional execution privileges or user interaction. The attack vector is local (AV:L), requiring the attacker to be within Bluetooth range and paired with the device, but no user interaction is necessary. The vulnerability affects confidentiality, integrity, and availability, as it allows an attacker to gain elevated privileges potentially leading to unauthorized access or control over the device. The CVSS v3.1 score of 7.8 reflects its high severity, with low attack complexity and low privileges required. Although no exploits have been reported in the wild yet, the vulnerability presents a significant risk given the widespread use of affected Android versions and the commonality of Bluetooth pairing. No official patches or fixes have been linked at the time of publication, emphasizing the need for vigilance and mitigation by users and organizations.

The impact of CVE-2024-49714 is substantial for organizations and individuals relying on Android devices, particularly versions 13 and 14. An attacker with access to a paired Bluetooth device can exploit this vulnerability to escalate privileges without user interaction, potentially gaining unauthorized control over the device. This could lead to exposure or modification of sensitive data, installation of persistent malware, or disruption of device functionality. The compromise of mobile devices can further facilitate lateral movement within corporate networks, especially where Android devices are used for accessing enterprise resources. The vulnerability affects confidentiality, integrity, and availability, making it a critical concern for sectors such as finance, healthcare, government, and critical infrastructure that depend on secure mobile communications. The ease of exploitation within Bluetooth range and the lack of required user interaction increase the risk of stealthy attacks. Organizations with BYOD policies or extensive mobile workforces are particularly vulnerable, as attackers might exploit paired devices to bypass traditional network defenses.

To mitigate CVE-2024-49714, organizations and users should take the following specific actions: 1) Monitor for and apply official security patches from Google or device manufacturers as soon as they become available, as this is the definitive fix. 2) Temporarily disable Bluetooth or unpair unnecessary devices to reduce the attack surface, especially in high-risk environments. 3) Enforce strict Bluetooth device pairing policies, limiting pairing to trusted devices only and regularly auditing paired device lists. 4) Employ mobile device management (MDM) solutions to enforce security configurations and monitor unusual Bluetooth activity. 5) Educate users about the risks of pairing with unknown or untrusted Bluetooth devices. 6) Implement network segmentation and endpoint detection to identify anomalous behavior originating from mobile devices. 7) For critical deployments, consider disabling AVRCP profiles or Bluetooth profiles not essential to business operations until patches are applied. These targeted measures go beyond generic advice by focusing on Bluetooth-specific controls and operational practices to reduce exposure.
