This vendor page is titled "ViRobot Unix/Linux Server Security
Vulnerability Patch."

However, it goes on to describe a buffer overflow problem:

  1. Patch for Buffer Over Flow Vulnerability
  - Vulnerability Type
  : Buffer Over Flow

  - Introduction to Patch
  : Vulnerability Patch for BOF(Buffer Over Flow) via HTTP_COOKIE


There is no mention of directory traversal.

This inconsistency makes it unclear whether HAURI has specifically
fixed the directory traversal issue, and in addition it mentions
another potentially more serious issue that has likely been missed by
most advisory readers.
