CVE-2025-53530 in WeGIA
Summary
by MITRE • 07/07/2025
WeGIA is a web manager for charitable institutions. The Wegia server has a vulnerability that allows excessively long HTTP GET requests to a specific URL. This issue arises from the lack of validation for the length of the errorstr parameter. Tests confirmed that the server processes URLs up to 8,142 characters, resulting in high resource consumption, elevated latency, timeouts, and read errors. This makes the server susceptible to Denial of Service (DoS) attacks. This vulnerability is fixed in 3.3.0.

The vulnerability identified as CVE-2025-53530 affects WeGIA, a web management platform designed for charitable institutions. This system serves as a critical infrastructure component for organizations managing their online presence and administrative functions. The vulnerability manifests in the server's handling of HTTP GET requests to specific endpoints, where inadequate input validation creates a pathway for malicious exploitation. The flaw specifically targets the errorstr parameter within the URL structure, demonstrating a classic lack of proper boundary checking that has been documented in numerous security frameworks including CWE-20, which categorizes improper input validation as a fundamental weakness in software design.
The technical implementation of this vulnerability stems from the server's failure to enforce reasonable limits on URL length parameters. When processing HTTP GET requests containing excessively long errorstr parameters, the WeGIA server demonstrates resource exhaustion characteristics that directly align with DoS attack vectors. The confirmed maximum URL length of 8,142 characters represents a significant deviation from normal operational parameters and indicates that the system lacks proper request sanitization mechanisms. This vulnerability operates at the application layer and demonstrates how insufficient input validation can create cascading performance issues that degrade system functionality rather than simply failing gracefully.
From an operational impact perspective, this vulnerability creates substantial risk for charitable institutions relying on WeGIA for their digital infrastructure. The resource consumption patterns described include elevated latency, server timeouts, and read errors that can effectively render the service unavailable to legitimate users. The DoS characteristics make this vulnerability particularly dangerous as it can be exploited by attackers with minimal technical expertise to disrupt critical services for charitable organizations. The vulnerability's presence in the server's core request handling mechanism means that any user with access to the affected URLs can potentially trigger resource exhaustion, creating a scalable attack vector that could impact multiple institutional operations simultaneously.
The remediation for CVE-2025-53530 has been implemented in version 3.3.0 of the WeGIA platform, which addresses the root cause through proper input validation and length restriction mechanisms. This fix aligns with established security best practices for preventing resource exhaustion attacks and demonstrates the importance of implementing proper parameter validation at all levels of application processing. Organizations using WeGIA should prioritize immediate deployment of version 3.3.0 or later to mitigate this vulnerability. The solution likely involves implementing maximum length constraints for URL parameters, proper error handling for oversized requests, and potentially rate limiting mechanisms to prevent abuse of the system's request processing capabilities. This vulnerability serves as a reminder of the critical importance of input validation and resource management in web applications, particularly those serving critical infrastructure roles such as charitable institutions that depend on continuous availability for their operations.
