Analysis

Technical impact

EasyFlow .NET, a workflow automation product from DigiWin, contains an arbitrary file read flaw. Authenticated remote attackers can exploit the vulnerability to download any system files the application process can access, exposing sensitive data or configuration information.

Affected Systems

The vulnerability affects DigiWin:EasyFlow .NET. Affected product versions are not listed in the available data, so all released versions prior to the patch should be considered at risk.
