CVE-2025-53531 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 fid 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 CVE-2025-53531 vulnerability affects WeGIA, a web management platform designed for charitable institutions, exposing a critical denial of service weakness through improper input validation. This flaw specifically targets the fid parameter within HTTP GET requests to a designated URL endpoint, where the server fails to enforce any reasonable limits on parameter length. The vulnerability stems from inadequate sanitization practices that allow malicious actors to craft extraordinarily long URLs, with tests demonstrating the server's processing capability extending to 8,142 characters. This excessive parameter handling creates substantial computational overhead as the server attempts to parse and process these abnormally long requests, leading to significant resource exhaustion and system performance degradation.
The operational impact of this vulnerability manifests as severe service disruption through elevated latency, connection timeouts, and read errors that ultimately render the affected server unable to properly respond to legitimate requests. This resource consumption pattern aligns with classical denial of service attack vectors where computational resources are consumed in excess of normal operating parameters, effectively preventing legitimate users from accessing the charitable institution's web management services. The vulnerability represents a clear violation of secure coding practices and demonstrates insufficient input validation mechanisms that should have been implemented to prevent such excessive resource allocation scenarios. This weakness creates an ideal attack surface for adversaries seeking to disrupt service availability through resource exhaustion attacks.
From a cybersecurity perspective, this vulnerability maps directly to CWE-770, which addresses allocation of resources without proper limits or with insufficient monitoring, and also aligns with ATT&CK technique T1499.004 for network denial of service attacks. The lack of input length validation creates a pathway for attackers to consume disproportionate system resources, potentially leading to cascading failures within the web infrastructure. The fix implemented in version 3.3.0 addresses this by introducing proper parameter length validation and resource consumption monitoring. Organizations should implement immediate mitigations including URL length restrictions, request rate limiting, and enhanced logging to detect abnormal request patterns. Additionally, regular security assessments should validate that all input parameters are properly bounded to prevent similar issues across the entire application stack. The vulnerability underscores the critical importance of implementing proper resource management and input validation controls as fundamental defensive measures against denial of service threats.
