Loading vulnerability…
CVE-2013-10034 is an unrestricted file upload vulnerability in Kaseya KServer versions prior to 6.3.0.2. The vulnerable component is the uploadImage.asp endpoint, which accepts multipart/form-data POST requests and fails to enforce authentication and proper validation or sanitization of the supplied filename parameter. An unauthenticated attacker can abuse this behavior to upload a file to an arbitrary path, including a web-accessible directory, and use an .asp extension so that the uploaded file is treated as server-executable content. Once placed in a reachable web path, the attacker can request the uploaded ASP file and obtain arbitrary code execution on the target server. The issue was fixed in KServer 6.3.0.2 by removing the vulnerable uploadImage.asp endpoint.

This repository contains a single Metasploit module targeting an arbitrary file upload vulnerability in Kaseya KServer versions below 6.3.0.2 (CVE-2013-10034). The exploit leverages the /SystemTab/uploadImage.asp endpoint, which allows unauthenticated users to upload files to arbitrary locations. The module generates a payload (typically a reverse shell or meterpreter), wraps it in an ASP script, and uploads it to the server. The payload is then executed by sending a GET request to the uploaded ASP file, resulting in remote code execution as the IUSR user. The exploit is fully weaponized, allowing for customizable payloads and automated cleanup. The code is written in Ruby and is structured as a standard Metasploit exploit module, making use of Metasploit's HttpClient, EXE, and FileDropper mixins. The only relevant endpoints are the vulnerable uploadImage.asp and the uploaded ASP payload itself.
