OpenSTAManager is an open source management software for technical assistance and invoicing. OpenSTAManager v2.9.8 and earlier contain 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 the id_documenti GET parameter are integers before using them in SQL IN() clauses, allowing attackers to inject arbitrary SQL commands and extract sensitive data through XPATH error messages.

GHSA-4j2x-jh4m-fqv6 — OpenSTAManager has a SQL Injection in the Prima Nota module

Affected: Packagist: devcode-it/openstamanager

### Summary

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)

### Details

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:**

1. **Entry Point:** `/modules/primanota/add.php` (Lines 63-67) ```php $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.

2. **SQL Injection Point:** `/modules/primanota/add.php` (Line 306) ```php $id_anagrafica = $dbo->fetchOne('SELE…
