CVE-2025-56223 Details
Description
A lack of rate limiting in the component /Home/UploadStreamDocument of SigningHub v8.6.8 allows attackers to cause a Denial of Service (DoS) via uploading an excessive number of files.
A denial-of-service vulnerability has been identified in Ascertia SigningHub version 8.6.8 and prior. The issue arises in the Upload Document API component, where a lack of rate limiting allows attackers to upload an excessive number of files. This unrestricted file upload capability can lead to resource exhaustion, such as depleting disk space, increasing server load, or degrading overall performance.
It is recommended to implement rate limiting for the Upload Document API to prevent excessive file uploads. Users can update to SigningHub versions after 8.6.8, where this vulnerability has been addressed.
