CVE-2025-32329 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-2025-32329 represents a critical logic flaw within the Session.java file that undermines the security boundaries between user sessions on a device. This issue stems from improper access control mechanisms that fail to adequately validate user permissions when accessing image resources. The flaw exists across multiple functions within the session management code, creating a persistent weakness that allows unauthorized access to sensitive data. The vulnerability is particularly concerning because it enables local privilege escalation without requiring any additional execution privileges or user interaction, making it highly exploitable in targeted attack scenarios.
The technical root cause of this vulnerability can be classified as a logic error that violates fundamental security principles of least privilege and access control. According to CWE standards, this manifests as a weakness in the implementation of access control mechanisms, specifically CWE-284 which addresses improper access control. The flaw occurs when the session management functions fail to properly authenticate and authorize access requests for image resources, allowing one user session to bypass the normal permission checks that should restrict access to another user's data. This logical failure creates a direct pathway for privilege escalation where a malicious actor can leverage the existing session context to access resources outside their designated scope.
The operational impact of CVE-2025-32329 extends beyond simple data exposure to encompass potential system compromise through local privilege escalation. Attackers can exploit this vulnerability to access sensitive image files belonging to other users, potentially obtaining confidential information that could be used for further attacks or reconnaissance. The lack of user interaction requirements means that exploitation can occur automatically without any need for social engineering or additional attack vectors. This vulnerability directly maps to ATT&CK technique T1068 which covers local privilege escalation and T1005 which addresses data from local system. The vulnerability affects all users of the affected system and can be exploited by any process running with the same privileges as the target session.
Mitigation strategies for this vulnerability must address the core logic error within the Session.java functions through comprehensive code review and access control implementation. Organizations should implement proper session isolation mechanisms that enforce strict access control checks before allowing any resource access. The fix requires modifying the session management code to include robust validation of user permissions and authentication contexts for all image access operations. Additionally, implementing proper input validation and access control lists within the session management framework will prevent unauthorized cross-user resource access. Security teams should conduct thorough code audits to identify similar logic errors in other session management functions and establish automated testing procedures to prevent future occurrences. The remediation process should also include implementing proper logging and monitoring of access attempts to detect potential exploitation attempts and ensure compliance with security standards such as those outlined in ISO 27001 and NIST cybersecurity frameworks.
