# Title: Elektronischer Leitz-Ordner 10 - SQL Injection
# Author: Jens Regel, Schneider & Wulf EDV-Beratung GmbH & Co. KG
# Software: https://www.elo.com/en-de/
# CVE: N/A
# Affected Products:
# ELOenterprise 10 (ELO Access Manager <= 10.17.120)
# ELOenterprise 9 (ELO Access Manager <= 9.17.120)
# ELOprofessional 10 (ELO Access Manager <= 10.17.120)
# ELOprofessional 9 (ELO Access Manager <= 9.17.120)



# Description: 
# ELO is a commercial software product for managing documents and
# electronic content. Storage and organization is similar to classic
# paper-based document management. ELO belongs to the category of document
# management (DMS) and enterprise content management systems (ECM). DMS
# and ECM systems enable audit-proof archiving of documents and
# information requiring storage.

# We have discovered a time-based blind SQL injection vulnerability in the
# ELO Access Manager (<= 9.17.120 and <= 10.17.120) component that makes
# it possible to read all database content. The vulnerability exists in
# the HTTP GET parameter "ticket". For example, we succeeded in reading
# the password hash of the administrator user in the "userdata" table from
# the "eloam" database.

# Proof of Concept:
