CVE-2022-20441 is a high-severity elevation of privilege vulnerability affecting multiple versions of the Android operating system, specifically Android 10 through Android 13, including Android 12L. The flaw exists in the navigateUpTo method within the Task.java component of the Android framework. Due to a logic error, this method can inadvertently launch an unexported intent handler. Normally, unexported intent handlers are protected from external invocation, but this vulnerability allows a local attacker to exploit an intent trampoline mechanism within a targeted app to escalate privileges without requiring additional execution privileges or user interaction. An intent trampoline is a design pattern where an app uses an intermediate component to forward intents internally, often to manage permissions or control flow. The vulnerability is classified under CWE-276 (Incorrect Default Permissions), indicating improper access control logic. The CVSS v3.1 base score is 7.8, reflecting high severity, with attack vector Local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a significant risk for local privilege escalation on affected devices. The flaw could allow malicious apps or local attackers to gain elevated privileges, potentially leading to unauthorized access to sensitive data, modification of system settings, or disruption of device functionality.

For European organizations, the impact of CVE-2022-20441 is primarily on mobile devices running affected Android versions. Enterprises relying on Android devices for business operations, especially those handling sensitive or regulated data, face risks of local privilege escalation that could lead to data breaches or unauthorized access to corporate resources. This is particularly critical for sectors such as finance, healthcare, and government agencies where data confidentiality and integrity are paramount. The vulnerability could be exploited by malicious apps installed on employee devices or by attackers with physical or local access to the device, bypassing standard security controls. Additionally, compromised devices could serve as entry points for lateral movement within corporate networks. Given the widespread use of Android devices across Europe, failure to patch this vulnerability could undermine compliance with data protection regulations like GDPR, exposing organizations to legal and reputational consequences.

To mitigate CVE-2022-20441, European organizations should implement the following specific measures: 1) Ensure all Android devices are updated to the latest security patches provided by device manufacturers or Google, as this vulnerability requires patching at the OS level. 2) Employ Mobile Device Management (MDM) solutions to enforce timely OS updates and restrict installation of untrusted or potentially malicious applications that could exploit local privilege escalation. 3) Limit local access to devices by enforcing strong device lock policies, including biometric or PIN authentication, to reduce the risk of local exploitation. 4) Conduct regular security audits and vulnerability assessments on mobile endpoints to detect signs of compromise or privilege escalation attempts. 5) Educate users about the risks of installing apps from unverified sources and encourage adherence to corporate app usage policies. 6) For high-security environments, consider deploying endpoint detection and response (EDR) tools capable of monitoring suspicious local activity indicative of privilege escalation attempts. 7) Collaborate with device vendors to verify patch deployment status and request expedited updates if necessary.
