CVE-2022-20512 is a high-severity elevation of privilege vulnerability affecting Android 13. The flaw exists in the navigateUpTo method of the Task.java component, where improper input validation allows an attacker to launch an intent handler with a mismatched intent. This mismatch can be exploited locally to escalate privileges without requiring any additional execution privileges or user interaction. The vulnerability stems from CWE-20, which relates to improper input validation, indicating that the system fails to correctly verify or sanitize input parameters before processing them. Because the vulnerability is local and requires no user interaction, an attacker with limited privileges on an affected Android 13 device could exploit this flaw to gain higher privileges, potentially compromising confidentiality, integrity, and availability of the device. The CVSS v3.1 base score is 7.8, reflecting a high severity with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, meaning the attack requires local access, low attack complexity, low privileges, no user interaction, unchanged scope, and impacts confidentiality, integrity, and availability to a high degree. No known exploits are currently reported in the wild, and no patches or vendor project details are provided in the data, though the vulnerability was reserved as of October 2021 and published in December 2022. This vulnerability is significant because Android 13 is the latest major Android release, and many devices in use across Europe run this version or will upgrade to it, making the potential attack surface substantial. The flaw could be leveraged by malicious apps or local attackers to gain unauthorized access to sensitive data or system functions, undermining device security and user privacy.

For European organizations, especially those with employees using Android 13 devices for work or managing Android-based IoT and mobile endpoints, this vulnerability poses a serious risk. An attacker exploiting this flaw could escalate privileges on affected devices, potentially bypassing security controls and accessing sensitive corporate data, credentials, or internal resources. This could lead to data breaches, unauthorized access to enterprise applications, or disruption of mobile device management (MDM) policies. The impact extends to sectors with high mobile device usage such as finance, healthcare, government, and critical infrastructure, where compromised devices could serve as entry points for broader network intrusions. Since no user interaction is required, the attack could be automated or triggered silently, increasing the risk of stealthy compromise. Additionally, the vulnerability could be exploited by malicious insiders or through compromised apps installed on devices, making endpoint security monitoring and app vetting critical. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks, especially as threat actors develop proof-of-concept or weaponized exploits. Overall, the vulnerability threatens confidentiality, integrity, and availability of devices and data, potentially impacting business continuity and regulatory compliance under GDPR and other European data protection laws.

Apply official Android security updates as soon as they become available from device manufacturers or Google, prioritizing devices running Android 13. Implement strict application vetting policies to prevent installation of untrusted or suspicious apps that could exploit local vulnerabilities. Enforce least privilege principles on Android devices, limiting app permissions and restricting installation of apps from unknown sources. Use Mobile Device Management (MDM) solutions to monitor device compliance, detect unusual privilege escalations, and enforce security policies. Educate users about the risks of installing apps outside official app stores and the importance of timely updates. For organizations managing Android devices, consider deploying endpoint detection and response (EDR) tools capable of detecting anomalous local privilege escalation behaviors. Perform regular security audits and penetration testing on mobile device fleets to identify potential exploitation vectors related to this vulnerability. If possible, restrict physical or local access to devices to reduce the risk of local exploitation. Monitor threat intelligence feeds for any emerging exploits targeting CVE-2022-20512 to enable rapid response.
