Service hang via unrestricted recursive crawling
Published Mar 3, 2025 · Updated Mar 4, 2025
Resource exhaustion in WeGIA before 3.2.16 allows remote attackers to make the web server unresponsive through aggressive crawling. Public directory listings and dynamic sort parameters generate recursively distinct URLs, while the server accepts their resulting request volume without rate or crawl limits. No authentication or user interaction is required; sustained spidering causes HTTP 5xx responses or a service hang, without reported data exposure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
