CVE-2025-53531: CWE-770: Allocation of Resources Without Limits or Throttling in LabRedesCefetRJ WeGIA
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.
AI Analysis
Technical Summary
CVE-2025-53531 is a high-severity vulnerability affecting versions of the WeGIA web management platform prior to 3.3.0. WeGIA is a web-based management system designed for charitable institutions, developed by LabRedesCefetRJ. The vulnerability arises from improper handling of the 'fid' parameter in HTTP GET requests, where the server fails to enforce limits on the length of this parameter. Testing has demonstrated that the server accepts URLs with 'fid' parameters up to 8,142 characters long, which leads to excessive resource consumption. This lack of input validation and throttling causes the server to experience elevated latency, timeouts, and read errors, effectively making it vulnerable to Denial of Service (DoS) attacks. The vulnerability is categorized under CWE-770, which concerns allocation of resources without limits or throttling, a common cause of DoS conditions. The CVSS 4.0 base score is 8.7, indicating a high severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges or user interaction required (PR:N/UI:N), and a high impact on availability (VA:H). No known exploits are currently reported in the wild, and the issue has been addressed in WeGIA version 3.3.0. The vulnerability does not impact confidentiality or integrity but significantly affects availability by enabling attackers to overwhelm the server with oversized requests, leading to service disruption.
Potential Impact
For European organizations using WeGIA to manage charitable or non-profit institutions, this vulnerability poses a significant risk of service disruption. A successful exploitation could render the web management platform unavailable, interrupting critical administrative and operational functions. This could affect donation processing, volunteer coordination, and beneficiary management, potentially damaging organizational reputation and trust. Given that the vulnerability requires no authentication or user interaction, attackers can remotely launch DoS attacks with relative ease. The impact is particularly severe for organizations with limited IT resources or those relying heavily on WeGIA for daily operations. Additionally, prolonged downtime could lead to regulatory compliance issues, especially under EU data protection and service availability mandates. Although no data breach is indicated, the unavailability of services can indirectly affect stakeholders and beneficiaries dependent on these platforms.
Mitigation Recommendations
Organizations should prioritize upgrading WeGIA installations to version 3.3.0 or later, where the vulnerability is fixed. Until patching is possible, implementing web application firewall (WAF) rules to detect and block excessively long HTTP GET requests targeting the 'fid' parameter can mitigate exploitation attempts. Rate limiting and request size restrictions at the network perimeter or reverse proxy level should be enforced to prevent resource exhaustion. Monitoring server logs for abnormal request patterns and latency spikes can provide early warning signs of attempted DoS attacks. Additionally, deploying DoS protection services or solutions that can absorb or filter malicious traffic will enhance resilience. It is also advisable to conduct regular security assessments and update incident response plans to include scenarios involving application-layer DoS attacks. Finally, organizations should engage with the vendor for timely updates and security advisories.
