What is CVE-2013-10034?
A significant vulnerability exists in Kaseya KServer that allows unauthenticated users to upload files to arbitrary directories through the uploadImage.asp endpoint. This flaw arises from inadequate input validation and authentication checks, permitting an attacker to upload a crafted file with an .asp extension. Once successfully uploaded, such files can be executed, potentially leading to arbitrary code execution with the privileges of the IUSR account. The issue was addressed in version 6.3.0.2 by eliminating the vulnerable endpoint.
