CVE-2024-40653 is a vulnerability identified in Google Android operating system versions 13, 14, and 15, specifically within multiple functions of the ConnectionServiceWrapper.java component. The flaw stems from a logic error that allows a permission to be retained indefinitely in the background, effectively bypassing normal permission revocation mechanisms. This condition enables a local attacker with limited privileges to escalate their privileges without requiring additional execution rights. The vulnerability requires user interaction to be exploited, such as convincing the user to perform an action that triggers the flawed logic. The issue is categorized under CWE-287, indicating improper authentication or authorization controls. The vulnerability impacts confidentiality, integrity, and availability, as an attacker gaining elevated privileges can access sensitive data, modify system settings, or disrupt device operations. The CVSS v3.1 base score is 7.3, with vector AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H, indicating local attack vector, low attack complexity, low privileges required, user interaction needed, unchanged scope, and high impact on confidentiality, integrity, and availability. No patches or known exploits have been reported at the time of publication, but the vulnerability's presence in recent Android versions makes it a significant risk for users and organizations relying on these platforms.

The vulnerability allows a local attacker to escalate privileges on affected Android devices, potentially gaining persistent elevated permissions. This can lead to unauthorized access to sensitive information, modification or deletion of critical data, and disruption of device functionality. For organizations, this could result in compromised mobile endpoints, leading to data breaches, unauthorized access to corporate resources, and lateral movement within networks if devices are used as entry points. The requirement for user interaction limits remote exploitation but does not eliminate risk, especially in environments where users may be targeted with social engineering or malicious applications. The lack of a patch increases exposure time, and the presence in widely used Android versions (13-15) means a large user base is affected. This vulnerability could be leveraged in targeted attacks against high-value individuals or organizations, particularly those with sensitive mobile workflows.

1. Monitor official Google security advisories and apply patches immediately once available. 2. Limit installation of applications from untrusted sources to reduce the risk of malicious apps exploiting this vulnerability. 3. Educate users about the risks of interacting with suspicious prompts or applications to minimize user interaction exploitation vectors. 4. Employ mobile device management (MDM) solutions to enforce strict permission controls and monitor unusual permission retention behaviors. 5. Use runtime application self-protection (RASP) or endpoint detection and response (EDR) tools capable of detecting privilege escalation attempts on Android devices. 6. Temporarily restrict or disable features relying on ConnectionServiceWrapper functionality if feasible until patches are released. 7. Conduct regular security audits and penetration testing on mobile environments to identify potential exploitation attempts.
