CVE-2025-32328 in Android
Summary
by MITRE • 12/08/2025
In multiple functions of Session.java, there is a possible way to view images belonging to a different user of the device due to a logic error in the code. 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-2025-32328 resides within the Session.java file where multiple functions contain a logic error that allows unauthorized access to user images. This flaw represents a critical security issue that undermines the integrity of user data isolation mechanisms. The vulnerability stems from improper access control implementation where the code fails to adequately verify user permissions when accessing image resources, creating a path for privilege escalation without requiring additional execution privileges or user interaction.
This security flaw operates at the application level and specifically targets the session management component of the system. The logic error manifests when multiple functions within Session.java fail to properly validate whether the requesting user has legitimate access rights to the requested image resources. The vulnerability is classified under CWE-284 which addresses improper access control issues, where the system fails to properly enforce access restrictions. The absence of proper authentication checks during image retrieval operations allows any authenticated user to potentially access image data belonging to other users on the same device.
The operational impact of this vulnerability extends beyond simple data exposure, as it enables local privilege escalation without additional execution privileges. This means that an attacker who has already gained basic system access can leverage this flaw to escalate their privileges and gain access to sensitive user data. The vulnerability does not require user interaction for exploitation, making it particularly dangerous as it can be automatically triggered by malicious processes running with the same user privileges. The flaw essentially creates a backdoor within the session management system that bypasses normal access control mechanisms.
The implications of this vulnerability align with ATT&CK technique T1078 which covers valid accounts and T1068 which addresses additional privileges. The system's failure to properly enforce access control creates an environment where unauthorized data access becomes possible through legitimate session management pathways. This vulnerability represents a fundamental breakdown in the principle of least privilege, where users can access resources beyond their intended scope. The lack of user interaction requirements makes this particularly concerning for automated exploitation scenarios.
Mitigation strategies should focus on implementing robust access control checks within all functions of Session.java that handle image resources. The primary fix involves adding proper user authentication verification before any image access operations, ensuring that each function validates the requesting user's identity against the target resource's ownership. Security patches should enforce strict session validation mechanisms and implement proper access control lists that prevent cross-user resource access. Organizations should also consider implementing additional monitoring and logging of session management activities to detect unauthorized access attempts. Regular security audits of session management components should be conducted to identify similar logic errors that could create similar privilege escalation paths.
