*Vulnerability Findings*

1. *SQL Injection* [Post Auth]


DocuClass web application contains a SQL injection vulnerability.


CWE-89: Improper Neutralization of Special Elements used in an SQL Command
('SQL Injection')


DocuClass web application contains a SQL injection vulnerability due to the
application failing to validate user input. Multiple parameters are
vulnerable.


*Vulnerable URLs & parameters:*

A. POST request - /dcrpcserver.php [parameter - uid]

B. GET request -

/e-forms/dcformsserver.exe?action=createimagepdf&documentid=1408648&userid=755

[parameter - userid]


*Impact*

database, execute code, and compromise the host system.

3. *Cross-Site Scripting*


DocuClass web application lacks strong input validation, and multiple urls
& parameters are vulnerable to cross-site scripting (CWE-79) attacks.


*Impact*

An attacker may be able to execute arbitrary scripts/code in the context of
the user's browser.


4. *Vulnerable to Cross-Site Request Forgery*


The application does not have a CSRF Token generated per page and / or per
(sensitive) function.


*Impact*

Successful exploitation of this vulnerability can allow silent execution of
unauthorized actions in the application such as configuration changes,
(potentially) deleting stored documents, running reports, changing
passwords, filling disk space via repeated duplicate copying of documents,
etc.
