CVE-2025-53409 in File Station
Summary
by MITRE • 11/07/2025
An allocation of resources without limits or throttling vulnerability has been reported to affect File Station 5. If a remote attacker gains a user account, they can then exploit the vulnerability to prevent other systems, applications, or processes from accessing the same type of resource.
We have already fixed the vulnerability in the following version: File Station 5 5.5.6.5018 and later

This vulnerability represents a critical resource exhaustion issue within File Station 5 that falls under the category of insufficient resource management and lacks proper allocation limits or throttling mechanisms. The flaw enables a remote attacker who has already compromised a user account to systematically consume system resources without constraints, effectively creating a denial of service condition that impacts the availability of critical services and applications. The vulnerability specifically targets resource allocation patterns where the system fails to implement adequate safeguards against uncontrolled consumption of computational resources, making it particularly dangerous in enterprise environments where file sharing and storage services are fundamental to operations.
The technical implementation of this vulnerability stems from the absence of resource throttling mechanisms within the File Station 5 application. When a malicious user with legitimate credentials exploits this weakness, they can trigger unlimited resource allocation requests that overwhelm system capabilities and prevent legitimate users from accessing the same resources. This type of vulnerability aligns with CWE-770, which addresses allocation of resources without limits or throttling, and represents a classic example of how insufficient resource management can lead to system-wide availability issues. The attack vector requires only a valid user account, making it particularly concerning as it can be exploited by insiders or compromised accounts without requiring additional privilege escalation.
The operational impact of this vulnerability extends beyond simple service disruption to encompass broader system stability and business continuity concerns. When exploited, the vulnerability can cause cascading failures where legitimate file access operations become unavailable, potentially affecting critical business processes that depend on file sharing and storage services. The resource exhaustion can manifest as system slowdowns, application crashes, or complete service outages that require manual intervention to resolve. Organizations using File Station 5 in production environments face significant risk of operational disruption, particularly in scenarios where the application serves as a central component of their file management infrastructure. This vulnerability particularly impacts environments with limited computational resources where resource contention can quickly escalate into critical system failures.
The remediation for this vulnerability requires immediate deployment of File Station 5 version 5.5.6.5018 or later, which implements proper resource allocation limits and throttling mechanisms. Organizations should conduct comprehensive testing of the updated version in their environments to ensure compatibility and verify that the resource management improvements function as intended. Additionally, system administrators should implement monitoring solutions to detect unusual resource consumption patterns that might indicate exploitation attempts. The fix addresses the underlying CWE-770 issue by introducing proper resource limits and allocation controls that prevent unbounded resource consumption. Security teams should also consider implementing additional controls such as connection rate limiting and resource usage quotas to provide defense-in-depth protection against similar vulnerabilities in other components of their infrastructure. This vulnerability highlights the importance of following the principle of least privilege and implementing proper resource management controls as outlined in various cybersecurity frameworks including the NIST Cybersecurity Framework and ISO 27001 standards.
