CVE-2025-32350 in Android
Summary
by MITRE • 09/04/2025
In maybeShowDialog of ControlsSettingsDialogManager.kt, there is a possible overlay of the ControlsSettingsDialog due to a tapjacking/overlay attack. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

The vulnerability identified as CVE-2025-32350 resides within the ControlsSettingsDialogManager.kt file where the maybeShowDialog function presents a potential security risk through improper handling of overlay windows. This flaw specifically affects the ControlsSettingsDialog component and creates an avenue for malicious actors to exploit the application's user interface elements. The vulnerability is classified as a tapjacking or overlay attack vector that allows unauthorized parties to manipulate the dialog display mechanism. The security implications extend beyond simple user interface manipulation as this weakness can potentially enable local privilege escalation without requiring any additional execution privileges or user interaction for exploitation. This makes the vulnerability particularly dangerous as it can be triggered automatically without any user engagement, representing a significant security risk in mobile or embedded systems where such dialog interfaces are commonly used.
The technical flaw manifests in the ControlsSettingsDialogManager.kt implementation where the maybeShowDialog method fails to properly validate or secure the overlay state of the dialog window. This weakness creates an opportunity for malicious applications or processes to position themselves over the legitimate dialog interface, potentially intercepting user interactions or displaying deceptive content. The vulnerability directly relates to CWE-691 which addresses insufficient control over overlay or popup windows, and aligns with ATT&CK technique T1056.001 focusing on input injection attacks through overlay manipulation. The absence of user interaction requirements for exploitation indicates that the vulnerability operates at a system level where the overlay mechanism can be triggered programmatically without user consent, making it particularly concerning for applications that handle sensitive controls or settings. The flaw essentially allows an attacker to create a false dialog interface that can deceive users into providing information or performing actions they would not normally consent to.
The operational impact of this vulnerability extends to potential privilege escalation scenarios where an attacker could leverage the overlay capability to gain elevated system permissions. Since no additional execution privileges are required for exploitation, the vulnerability can be exploited from a low-privilege context to potentially achieve system-level access. The automatic triggering capability means that this vulnerability can be exploited in the background without user awareness, creating a stealthy attack vector that could remain undetected for extended periods. This type of vulnerability is particularly dangerous in environments where applications handle sensitive data or control critical system functions, as the overlay attack could be used to capture credentials, manipulate settings, or redirect user attention to malicious content. The vulnerability affects the integrity of the user interface layer and can compromise the trust model that users place in legitimate application dialogs, potentially leading to cascading security issues throughout the system.
Mitigation strategies for CVE-2025-32350 should focus on implementing robust overlay protection mechanisms within the ControlsSettingsDialogManager.kt implementation. Security measures must include validation of dialog overlay states, proper permission checks before displaying sensitive interfaces, and implementation of secure dialog presentation protocols that prevent unauthorized applications from positioning overlays over legitimate interfaces. The solution should incorporate defensive programming practices that ensure dialog windows maintain proper z-order positioning and that overlay attempts are properly detected and blocked. Additionally, implementing proper access controls and privilege separation mechanisms can help prevent unauthorized escalation of privileges through this vulnerability. Organizations should conduct thorough code reviews focusing on overlay and dialog management components, and consider implementing runtime monitoring to detect anomalous overlay behavior. The fix should align with security best practices outlined in OWASP mobile security project recommendations for preventing overlay attacks and should be validated through comprehensive security testing to ensure that legitimate overlay functionality remains intact while malicious overlay attempts are properly mitigated.
