Product:

WebLog Expert Web Server Enterprise v9.4
WebLog Expert is a fast and powerful access log analyzer. It will give you information about your site's visitors:
activity statistics, accessed files, paths through the site, information about referring pages, search engines, browsers,
operating systems, and more. The program produces easy-to-read reports that include both text information (tables) and charts.
Security Issue:
================
The "WebServer.cfg" under "ProgramData\WebLog Expert\WebServer\" used by WebLog Expert Web Server Enterprise 9.4
has weak permissions (BUILTIN\Users:(ID)C), which allows local users to set a cleartext password and login as admin.
A standard non Windows Administrator user can edit the 'WebServer.cfg' file under "C:\ProgramData\WebLog Expert\WebServer"
set to a cleartext password and login as admin.
e.g.
C:\ProgramData\WebLog Expert\WebServer>cacls * | more
C:\ProgramData\WebLog Expert\WebServer\WebServer.cfg BUILTIN\Users:(ID)C
BUILTIN\Administrators:(ID)C
NT AUTHORITY\SYSTEM:(ID)F
BUILTIN\Administrators:(ID)F
Exploit/POC:
=============
Login as a 'Standard' Windows user
Comment out the Admin hashed password using ';' then add any cleartext password as follows.
