CVE-2020-13128

Name of the Vulnerable Software and Affected Versions Manolo GWTUpload version 1.0.3

Description An issue was discovered in the server/UploadServlet.java, which is the servlet for handling file upload. It accepts a delay parameter that causes a thread to sleep. This can be abused to cause all of a server's threads to sleep, leading to denial of service.

Recommendations For Manolo GWTUpload version 1.0.3, consider disabling the delay parameter in the UploadServlet.java to prevent abuse. As a temporary workaround, restrict access to the UploadServlet.java to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
