CVE-2025-7699 in ADM
Summary
by MITRE • 07/16/2025
An improper access control vulnerability was found in the EZ Sync Manager of ADM, which allows authenticated users to copy arbitrary files from the server file system into their own EZSync folder. The vulnerability is due to a lack of authorization checks on the file parameter of the HTTP request. Attackers can exploit this flaw to access files outside their authorized scope, provided the file has readable permissions for other users on the underlying OS. This can lead to unauthorized exposure of sensitive data. Affected products and versions include: from ADM 4.1.0 to ADM 4.3.3.RH61 as well as ADM 5.0.0.RIN1 and earlier.

The CVE-2025-7699 vulnerability represents a critical improper access control flaw within the EZ Sync Manager component of ADM software, demonstrating a fundamental breakdown in authorization mechanisms that directly compromises data security. This vulnerability exists in versions ranging from ADM 4.1.0 through 4.3.3.RH61 and extends to ADM 5.0.0.RIN1 and earlier releases, indicating a widespread issue affecting multiple product lines. The flaw specifically manifests in the lack of proper authorization checks on the file parameter within HTTP requests, creating an exploitable pathway for authenticated users to escalate their privileges beyond intended boundaries. The vulnerability maps directly to CWE-284, which categorizes improper access control as a critical weakness in software security architecture, and aligns with ATT&CK technique T1078.004 for valid accounts and T1566.001 for valid accounts, as attackers leverage legitimate authenticated sessions to gain unauthorized access to restricted resources.
The technical implementation of this vulnerability stems from inadequate input validation and authorization enforcement within the EZ Sync Manager's file handling routines. When authenticated users submit HTTP requests containing file parameters, the system fails to validate whether the requesting user has proper authorization to access the specified file path. This absence of proper access control checks allows malicious actors to manipulate the file parameter to reference files outside their authorized scope, provided those files possess readable permissions for other users within the underlying operating system. The vulnerability essentially creates a directory traversal-like condition within the file synchronization framework, where the boundary checking mechanisms are bypassed through the lack of proper authorization validation. This flaw is particularly dangerous because it operates within the context of authenticated users, meaning attackers do not need to perform initial authentication attacks but can exploit existing legitimate sessions to access unauthorized data.
The operational impact of this vulnerability extends far beyond simple data exposure, potentially leading to significant information disclosure and data breach scenarios within enterprise environments. Attackers can leverage this flaw to access sensitive files such as configuration data, user credentials, system logs, or proprietary business information that should remain restricted to authorized personnel only. The vulnerability's exploitation requires minimal technical skill, as it relies on manipulating existing authenticated sessions rather than complex attack vectors, making it particularly dangerous for organizations with insufficient monitoring and access control measures. Organizations using affected ADM versions face potential compliance violations under data protection regulations such as gdpr, hipaa, and pci dss, as unauthorized data access constitutes a direct breach of information security policies and regulatory requirements. The impact is amplified when considering that the vulnerability affects multiple versions of the software, suggesting that organizations may have extended periods of exposure without proper patching or mitigation measures.
Mitigation strategies for CVE-2025-7699 should focus on immediate implementation of proper authorization controls and input validation mechanisms within the EZ Sync Manager component. Organizations must implement strict validation of file paths and parameters within HTTP requests to prevent unauthorized access to system resources, ensuring that all file operations are properly authenticated and authorized before execution. The most effective immediate solution involves applying vendor-provided patches or updates that address the specific authorization bypass vulnerability, while organizations should also consider implementing network segmentation and monitoring controls to detect anomalous file access patterns. Additional protective measures include restricting file permissions on the underlying operating system to minimize the impact of potential exploitation, implementing comprehensive audit logging for all file access operations, and establishing strict access control policies that enforce the principle of least privilege. Organizations should also conduct thorough security assessments to identify and remediate similar authorization flaws in other components of their software infrastructure, as this vulnerability demonstrates a systemic weakness in access control implementation that may exist elsewhere within the application architecture. The remediation process should align with security frameworks such as nist cybersecurity framework and iso 27001, ensuring that the implemented controls meet established security standards and regulatory compliance requirements.
