CVE-2025-48604 in Android
Summary
by MITRE • 12/08/2025
In multiple locations, there is a possible way to read files from another user due to a missing permission check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

This vulnerability represents a critical access control flaw that exists across multiple system components where proper permission validation has been omitted. The issue manifests as a missing permission check that allows unauthorized users to access files belonging to other users within the same system environment. Such a weakness directly violates fundamental security principles of least privilege and mandatory access control that are essential for maintaining data isolation and confidentiality. The vulnerability is classified under CWE-284 which specifically addresses improper access control mechanisms, making it a significant concern for system integrity and data protection. The absence of proper authorization checks creates an exploitable condition where malicious actors can traverse file system boundaries without requiring additional privileges or execution capabilities.
The technical implementation of this flaw suggests that the affected system components lack proper validation of user permissions before allowing file access operations. This could occur in various contexts including file system operations, database queries, network communications, or application interfaces where access controls should be enforced. The vulnerability's impact extends beyond simple information disclosure as it represents a fundamental breakdown in the system's security architecture. Attackers can exploit this condition to gain unauthorized access to sensitive user data, system configuration files, or application-specific information that should remain protected. The lack of user interaction requirement makes this vulnerability particularly dangerous as it can be exploited automatically without any need for social engineering or complex attack chains. This characteristic aligns with ATT&CK technique T1005 which focuses on data from local system sources, demonstrating how such flaws can enable adversaries to collect information without requiring direct user engagement.
The operational implications of this vulnerability are severe and multifaceted across different security domains. Organizations may experience unauthorized data exposure that could include personal information, proprietary data, system credentials, or confidential business information. The vulnerability's persistence across multiple locations suggests that it may be a systemic design flaw rather than an isolated incident, potentially affecting various applications or system components simultaneously. This widespread nature increases the attack surface and makes comprehensive remediation more complex. The vulnerability's exploitation does not require additional execution privileges, meaning that even users with minimal system access can potentially exploit it to gain broader information access. This characteristic reduces the barrier to exploitation and makes the vulnerability particularly attractive to attackers who may be operating with limited privileges.
Mitigation strategies should focus on implementing comprehensive permission validation mechanisms throughout the affected system components. Security controls must be strengthened to ensure that all file access operations include proper authorization checks before allowing data retrieval. Organizations should implement robust access control lists, mandatory access controls, and privilege separation mechanisms to prevent unauthorized file access. The remediation process should include code reviews to identify and address all locations where similar permission checks are missing, ensuring that proper authentication and authorization procedures are enforced. Regular security assessments and penetration testing should be conducted to identify additional instances of similar vulnerabilities. System administrators should implement monitoring and logging mechanisms to detect unauthorized access attempts, while also applying principle of least privilege configurations to minimize the potential impact of such vulnerabilities. The implementation of automated security scanning tools can help identify and remediate similar permission-related flaws across the entire system infrastructure, preventing similar vulnerabilities from persisting in future system updates or modifications.
