This vulnerability resides within the device firmware (fastboot) and requires local physical access or a wired connection to a device for exploitation. It is not reachable over the public internet in normal deployments.

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability impacts Google Android devices, specifically related to the fastboot firmware. The core issue involves uninitialized data that can be exploited to disclose information. This could lead to unauthorized access to sensitive data on the device.

  • Vulnerable: Google Android fastboot firmware
  • Weakness: Uninitialized data allows information disclosure
  • Impact: Local information disclosure

Attack Path

How an attacker could exploit the issue

This vulnerability allows for the disclosure of local information without requiring additional execution privileges. Exploitation does not necessitate user interaction and can occur through uninitialized data. The attack vector is local, meaning an attacker must have direct access to the affected system.

  • Local exposure required.
  • Attacker gains local access.
  • Uninitialized data triggers information disclosure.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability allows for the disclosure of local information due to uninitialized data. Exploitation does not require additional execution privileges and occurs without user interaction. Attackers with local access to a device could potentially leverage this to gain unauthorized information.

  • Likely attacker skill level: Basic
  • Required access or conditions: Local access
  • Business risk or urgency: Medium

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

The organization should address a potential information disclosure vulnerability in its Android Pixel devices. This vulnerability could allow unauthorized access to sensitive data on the device without requiring additional privileges or user interaction. As this issue is listed in the Known Exploited Vulnerabilities Catalog, immediate action is recommended to manage the associated business risk.

  • Find all affected Android Pixel devices.

Frequently asked questions

What is the Google Android fastboot firmware and what is it used for?

The Google Android fastboot firmware is a mode that allows for unlocking, flashing, and locking affected devices. It's a crucial component for developers and advanced users who need to modify or update the device's software at a low level.

What type of vulnerability is CVE-2024-29745 and how does it work?

CVE-2024-29745 is an Information Disclosure vulnerability stemming from uninitialized data. This means that improperly handled data can be exposed, leading to sensitive information being revealed on the device without the need for special permissions or user action.

What conditions are needed for CVE-2024-29745 to be exploited?

Exploitation requires an attacker to have local access to the affected device. User interaction is not necessary for the vulnerability to be triggered, and no additional execution privileges are needed by the attacker to access the disclosed information.

Who should be concerned about this vulnerability based on its access requirements?

Organizations with Android devices that have local access points or wired connections should be concerned. Since exploitation requires local access, it is classified as an internal threat, meaning it's not reachable over the public internet in normal scenarios.

What is the first step to respond to this Android vulnerability?

The first step is to identify all affected Android devices within your organization. After identification, isolating these devices can help reduce potential exposure while you prepare to apply vendor fixes and confirm their successful implementation.
