Rule Category

SERVER-OTHER -- Snort has detected traffic exploiting vulnerabilities in a server in the network.

Alert Message

SERVER-OTHER Progress WhatsUp Gold WriteDataFile directory traversal attempt

Rule Explanation

This rule looks for a .NET Message Framing Protocol sized envelope record that includes the "WriteDataFile" operation together with a parent directory traversal pattern in the request payload. Successful exploitation allows an attacker to write arbitrary files to arbitrary locations on the target system, potentially achieving remote code execution.

What To Look For

This rule fires on attempts to exploit a directory traversal vulnerability in Progress WhatsUp Gold servers.

Adversaries may attempt to take advantage of a weakness in an Internet-facing computer or program using software, data, or commands in order to cause unintended or unanticipated behavior. The weakness in the system can be a bug, a glitch, or a design vulnerability. These applications are often websites, but can include databases (like SQL), standard services (like SMB or SSH), network device administration and management protocols (like SNMP and Smart Install), and any other applications with Internet accessible open sockets, such as web servers and related services.

Rule Vulnerability

Directory Traversal

A Directory Traversal attack targets HTTP traffic and allows the attacker to access directories outside the applications own, potentially exposing sensitive system files to leakage or overwriting. This is also known as Directory Climbing, Path Traversal, or Backtracking. An alert on this kind of attack indicates a vulnerability in security validation of user input that allows a "traverse to parent directory" or "../" command to pass through. Protect your site by filtering all user input, removing any characters but the allowed data.
