Title: Persits AspUpload Default Scripts Exploitable Vulnerability

Severity: HIGH

Description:

AspUpload is an ASP extension which allows remote users to upload files through html forms.

One sample script installed with AspUpload allows a user to upload a file to the directory c:\upload on the web server. This script accepts the file name to be uploaded to as a hidden form value. This file name is vulnerable to a ../ directory traversal attack, allowing the remote user to specify any file on the c: drive.

A second sample script allows a remote user to browse directories, and download any file located on the server.

The sample scripts are located in the directory C:\Program Files\Persits Software\AspUpload\Samples. Vulnerable scripts include:

UploadScript11.asp
DirectoryListing.asp


Version 3.0 of AspUpload may also contain these sample scripts.

Affected Products:

  • Persits AspUpload 2.1.0
