CVE-2022-20511 is a medium-severity information disclosure vulnerability affecting Android 13 devices. The flaw exists in the getNearbyAppStreamingPolicy method within the DevicePolicyManagerService.java component. Specifically, the vulnerability arises due to a missing permission check, which allows a local attacker with limited privileges to access sensitive information without requiring additional execution privileges or user interaction. The vulnerability is classified under CWE-862 (Missing Authorization), indicating that the affected method fails to properly enforce authorization controls before disclosing information. Exploitation requires local access to the device, but no elevated privileges or user interaction is necessary, making it easier for malicious apps or local adversaries to leverage this flaw. The vulnerability impacts confidentiality (high impact) but does not affect integrity or availability. The CVSS v3.1 base score is 5.5, reflecting a medium severity level, with an attack vector of local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and unchanged scope (S:U). No known public exploits have been reported in the wild, and no patches or vendor advisories are linked in the provided data. The vulnerability is specific to Android 13, which is the latest major Android release, implying that devices running this version are susceptible if unpatched.

For European organizations, the impact of CVE-2022-20511 primarily concerns confidentiality breaches on Android 13 devices used within corporate environments. Since Android devices are widely used for mobile communications, enterprise applications, and BYOD (Bring Your Own Device) policies, unauthorized local information disclosure could expose sensitive corporate data or user information. Although exploitation requires local access, this could be achieved through malicious apps installed on employee devices or physical access by insiders. The lack of user interaction requirement increases the risk of stealthy data leaks. While the vulnerability does not affect system integrity or availability, the confidentiality compromise could lead to privacy violations, intellectual property exposure, or leakage of sensitive operational details. This is particularly critical for sectors handling sensitive data such as finance, healthcare, government, and critical infrastructure. Additionally, given the widespread adoption of Android devices in Europe, the vulnerability could be leveraged in targeted attacks or espionage campaigns against high-value targets. However, the medium severity and local attack vector limit the scale of impact compared to remote or privilege-escalation vulnerabilities.

To mitigate CVE-2022-20511, European organizations should implement the following specific measures: 1) Ensure all Android 13 devices are updated with the latest security patches as soon as they become available from device manufacturers or carriers, as Google or OEMs are expected to release fixes addressing this missing permission check. 2) Enforce strict application vetting policies to prevent installation of untrusted or potentially malicious apps that could exploit local vulnerabilities. 3) Utilize Mobile Device Management (MDM) solutions to restrict app permissions and monitor device behavior, limiting the ability of apps to access sensitive APIs or system services like DevicePolicyManagerService. 4) Educate employees on the risks of installing apps from unofficial sources and the importance of device security hygiene. 5) Implement physical security controls to prevent unauthorized physical access to devices, as local access is required for exploitation. 6) Monitor device logs and network traffic for unusual activity that could indicate attempts to exploit local vulnerabilities. 7) Consider deploying endpoint detection and response (EDR) tools capable of detecting suspicious local privilege usage or API calls related to device policy management. These targeted actions go beyond generic advice by focusing on controlling local access vectors, application permissions, and patch management specific to Android 13 environments.
