CVE-2025-48632 in Android
Summary
by MITRE • 12/08/2025
In setDisplayName of AssociationRequest.java, there is a possible way to cause CDM associations to persist after the user has disassociated them due to improper input validation. 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-2025-48632 resides within the AssociationRequest.java file, specifically in the setDisplayName method implementation. This flaw represents a critical security weakness that allows for improper input validation during the handling of CDM (Content Delivery Manager) associations. The vulnerability stems from insufficient validation of user-provided display names when establishing or modifying association states, creating a pathway for malicious input to bypass intended security controls. The issue manifests when users attempt to disassociate CDM elements, yet the system fails to properly terminate these associations due to the flawed validation mechanism. This represents a classic case of inadequate input sanitization that can be exploited to maintain unauthorized access to system resources. The vulnerability operates at the application level and specifically affects the association management functionality within the CDM framework, where display name parameters are processed without proper validation checks.
The technical exploitation of this vulnerability enables local privilege escalation without requiring any additional execution privileges or user interaction. This means that an attacker who can manipulate the setDisplayName method input parameters can potentially maintain persistent associations even after attempting to disassociate them. The flaw creates a persistent state where unauthorized access to CDM resources remains possible, effectively allowing attackers to maintain elevated privileges within the system. The vulnerability's classification as local privilege escalation indicates that while it doesn't require network access or user interaction, it can be leveraged by any local user with access to the affected application. This type of vulnerability aligns with CWE-20, which describes improper input validation, and demonstrates how inadequate parameter checking can lead to serious security implications. The lack of user interaction requirement makes this vulnerability particularly concerning as it can be exploited automatically without any human intervention.
The operational impact of CVE-2025-48632 extends beyond simple privilege escalation to encompass potential data exposure and system compromise. When CDM associations persist after disassociation attempts, attackers can maintain access to sensitive system resources, potentially enabling them to read, modify, or delete critical data. This persistent access can facilitate further exploitation attempts and may allow attackers to escalate their privileges beyond what was initially possible. The vulnerability affects the core association management functionality and can potentially impact multiple system components that rely on proper association handling. Organizations may experience unauthorized data access, system integrity compromises, and potential audit trail manipulation. The vulnerability's presence in a core system component means that the impact could be widespread across the affected platform. From an ATT&CK perspective, this vulnerability maps to privilege escalation techniques and can be leveraged as part of broader attack chains targeting system access control mechanisms.
Mitigation strategies for CVE-2025-48632 should focus on implementing robust input validation and sanitization measures within the setDisplayName method. The most effective approach involves adding comprehensive parameter validation that checks for malicious input patterns and ensures proper association state management. Organizations should implement proper input sanitization techniques that filter or reject potentially harmful display name values before processing them. Additionally, the system should enforce strict association state transitions and ensure that disassociation requests are properly enforced regardless of input values. Security patches should include enhanced validation logic that prevents the persistence of associations when users explicitly attempt to disassociate resources. System administrators should also consider implementing monitoring and alerting mechanisms to detect unusual association patterns that may indicate exploitation attempts. The fix should align with security best practices and incorporate proper error handling to prevent the propagation of invalid input values through the system. Regular security assessments and code reviews should be conducted to identify similar validation weaknesses in other system components that may be susceptible to analogous attacks.
