CVE-2022-36441 is a high-severity vulnerability identified in Zebra Enterprise Home Screen version 4.1.19. The core issue revolves around the misuse of the Gboard keyboard application, which is integrated or used by various applications within the Zebra Enterprise Home Screen environment. Specifically, this vulnerability allows an attacker to leverage Gboard to launch and operate multiple other applications that should be restricted by administrative policies. This bypasses the intended access controls and restrictions set by administrators, effectively breaking the principle of least privilege. The vulnerability is classified under CWE-284, which relates to improper access control. The CVSS 3.1 base score of 7.1 indicates a high impact, with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N highlighting that the attack requires local access with low complexity, minimal privileges, no user interaction, and results in high confidentiality and integrity impact without affecting availability. The vulnerability does not require user interaction, making it more dangerous in environments where an attacker or malicious insider has limited access. Although no known exploits are reported in the wild, the potential for abuse exists, especially in controlled enterprise environments where Zebra devices are deployed. Zebra Enterprise Home Screen is typically used in enterprise and industrial settings to manage device access and application control, so this vulnerability could undermine security policies designed to restrict application usage and data access.

For European organizations, especially those in logistics, manufacturing, retail, and warehousing sectors where Zebra devices are commonly deployed, this vulnerability poses a significant risk. The ability to bypass administrative restrictions and launch unauthorized applications can lead to unauthorized data access, data leakage, or manipulation of sensitive information, compromising confidentiality and integrity. This could facilitate insider threats or lateral movement by attackers who gain limited local access. The breach of access controls may also allow the execution of malicious payloads or unauthorized data exfiltration tools, potentially impacting compliance with GDPR and other data protection regulations. Additionally, the disruption of controlled application environments could affect operational workflows and device management, leading to operational inefficiencies or security policy violations. Given the high confidentiality and integrity impact, organizations could face reputational damage, regulatory penalties, and financial losses if exploited.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Immediately review and update Zebra Enterprise Home Screen to the latest available version or apply any vendor-provided patches once released. 2) Restrict local access to Zebra devices strictly to trusted personnel and enforce strong authentication mechanisms to prevent unauthorized physical or local access. 3) Implement device-level controls to limit or monitor the use of Gboard or other input methods that could be exploited to bypass restrictions. 4) Employ Mobile Device Management (MDM) or Enterprise Mobility Management (EMM) solutions to enforce application whitelisting and monitor application launches and usage patterns for anomalies. 5) Conduct regular audits of device configurations and access logs to detect any unauthorized application launches or policy violations. 6) Educate users and administrators about the risks of local privilege misuse and enforce strict operational procedures for device handling. 7) Consider isolating critical Zebra devices within secure network segments to limit potential lateral movement in case of compromise. These steps go beyond generic advice by focusing on controlling local access vectors, monitoring application behavior, and enforcing strict device management policies tailored to the Zebra device ecosystem.
