CVE-2019-25344 in MobileGo
Summary
by MITRE • 02/12/2026
Wondershare MobileGo 8.5.0 contains an insecure file permissions vulnerability that allows local users to modify executable files in the application directory. Attackers can replace the original MobileGo.exe with a malicious executable to create a new user account and add it to the Administrators group with full system access.

The vulnerability identified as CVE-2019-25344 affects Wondershare MobileGo version 8.5.0 and represents a critical insecure file permissions flaw that undermines the application's security model. This issue stems from improper access control mechanisms within the software installation directory where executable files are stored with insufficient permission restrictions. The vulnerability allows local attackers to escalate their privileges by manipulating the application's executable file, effectively bypassing the normal security boundaries that should protect system integrity.
This security weakness creates a direct path for privilege escalation attacks where an attacker can substitute the legitimate MobileGo.exe file with a malicious executable of their own creation. The malicious replacement file is designed to execute with elevated privileges and can create new user accounts within the system while simultaneously adding these accounts to the Administrators group. This combination of capabilities provides the attacker with complete system control, enabling them to perform any action that an administrator could execute, including installing software, modifying system configurations, accessing sensitive data, and potentially establishing persistent access through backdoor creation.
The technical exploitation of this vulnerability aligns with CWE-732: Incorrect Permission Assignment for Critical Resources, which specifically addresses situations where applications fail to properly enforce access controls on critical system resources. From an operational perspective, this vulnerability represents a significant risk to enterprise environments where Wondershare MobileGo might be deployed across multiple endpoints, as it could allow attackers to gain unauthorized administrative access to systems. The attack vector is particularly concerning because it requires minimal sophistication to execute, relying primarily on local access and basic file manipulation techniques rather than complex exploitation methods.
The impact of this vulnerability extends beyond immediate privilege escalation to encompass broader security implications including potential data exfiltration, system compromise, and lateral movement capabilities within networks. Organizations using this software should consider the vulnerability in the context of ATT&CK framework's privilege escalation techniques, particularly those involving application execution and account manipulation. The vulnerability also highlights the importance of proper application hardening practices, including the implementation of file integrity monitoring, regular security audits, and adherence to principle of least privilege concepts in software deployment.
Mitigation strategies should include immediate software updates from Wondershare to address the insecure file permissions issue, implementation of file access control mechanisms, and regular monitoring for unauthorized file modifications in application directories. System administrators should also consider deploying endpoint protection solutions that can detect and prevent file replacement activities, while maintaining regular security assessments to identify similar permission-related vulnerabilities in other installed applications. Additionally, organizations should implement network segmentation and access controls to limit the potential impact of successful exploitation, ensuring that even if one system is compromised, attackers cannot easily move laterally through the network infrastructure.
