CVE-2025-53530: 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 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.
AI Analysis
Technical Summary
CVE-2025-53530 is a high-severity vulnerability affecting the WeGIA web management software developed by LabRedesCefetRJ, which is used primarily by charitable institutions to manage their web services. The vulnerability is classified under CWE-770, indicating an issue with allocation of resources without proper limits or throttling. Specifically, the WeGIA server fails to validate the length of the 'errorstr' parameter in HTTP GET requests. Testing has shown that the server accepts URLs with this parameter up to 8,142 characters in length. This excessive input size leads to significant resource consumption, causing elevated latency, timeouts, and read errors on the server. As a result, an attacker can exploit this flaw to launch Denial of Service (DoS) attacks by sending excessively long HTTP GET requests, overwhelming the server's resources and rendering the service unavailable to legitimate users. The vulnerability does not require any authentication or user interaction and can be exploited remotely over the network. The CVSS 4.0 base score is 8.7, reflecting the high impact on availability and ease of exploitation. The issue is fixed in WeGIA version 3.3.0, but versions prior to this remain vulnerable. No known exploits are currently reported in the wild, but the nature of the vulnerability makes it a critical concern for affected organizations.
Potential Impact
For European organizations using WeGIA, particularly charitable institutions relying on this software for web management, the impact of CVE-2025-53530 can be significant. Successful exploitation can lead to service outages, disrupting critical operations such as donation processing, volunteer coordination, and communication with stakeholders. The DoS condition could damage the organization's reputation and trustworthiness, especially if prolonged downtime affects fundraising campaigns or public-facing services. Additionally, resource exhaustion on the server may cause collateral impacts on other hosted applications or services sharing the same infrastructure. Given that the vulnerability requires no authentication and can be triggered remotely, attackers can easily target these organizations from anywhere, increasing the risk of opportunistic or targeted attacks. The lack of current known exploits does not diminish the threat, as the vulnerability is straightforward to exploit once discovered. European organizations with limited IT security resources or delayed patch management processes are particularly vulnerable to disruption from this issue.
Mitigation Recommendations
To mitigate CVE-2025-53530, affected organizations should prioritize upgrading WeGIA to version 3.3.0 or later, where the vulnerability has been addressed. Until patching is possible, organizations should implement network-level protections such as rate limiting and request size restrictions on web servers or reverse proxies to block excessively long HTTP GET requests, specifically targeting the 'errorstr' parameter. Web Application Firewalls (WAFs) can be configured to detect and block anomalous URL lengths or patterns indicative of exploitation attempts. Monitoring server logs for unusual spikes in request lengths or latency can provide early warning signs of attempted exploitation. Additionally, deploying DoS mitigation services or appliances can help absorb or filter malicious traffic. It is also advisable to conduct regular security assessments and penetration tests to verify that the implemented controls effectively prevent exploitation. Finally, organizations should maintain an incident response plan tailored to DoS scenarios to minimize downtime and coordinate rapid recovery.
