{"id":"GHSA-27vf-3g4f-6jp7","aliases":["CVE-2025-23199"],"title":"LibreNMS Ports Stored Cross-site Scripting vulnerability","titleSource":"OSV","descriptionSource":"OSV","declaredSeverity":"MODERATE","description":"# StoredXSS-LibreNMS-Ports\n\n\n**Description:**\n\n\nStored XSS on the parameter:\n`/ajax_form.php` -> param: descr\n\nRequest:\n```http\nPOST /ajax_form.php HTTP/1.1\nHost: <your_host>\nX-Requested-With: XMLHttpRequest\nX-CSRF-TOKEN: <your_XSRF_token>\nContent-Type: application/x-www-form-urlencoded; charset=UTF-8\nCookie: <your_cookie>\n\ntype=update-ifalias&descr=%22%3E%3Cimg+src+onerror%3D%22alert(1)%22%3E&ifName=lo&port_id=1&device_id=1\n```\n\n\nof Librenms version 24.10.1 ([https://github.com/librenms/librenms](https://github.com/librenms/librenms)) allows remote attackers to inject malicious scripts. When a user views or interacts with the page displaying the data, the malicious script executes immediately, leading to potential unauthorized actions or data exposure.\n\n\n\n**Proof of Concept:**\n1. Add a new device through the LibreNMS interface.\n2. Edit the newly created device and select the \"ports\" section.\n3. In the \"Description\" field, enter the following payload: `\"><img src onerror=\"alert(1)\">`.\n4. Save the changes.\n5. The XSS vulnerability is triggered when accessing the \"ports\" tab, and the payload is executed again when hovering over the modified value in the \"Port\" field.\n\nPayload:\n![payload](https://github.com/user-attachments/assets/2f38b985-6684-403f-9d1f-e405f09a75bb)\n\nExecutes:\n![image](https://github.com/user-attachments/assets/b70a6e34-d52c-4113-b769-4e271e33de88)\nThe script execution vulnerability in the description field, as shown in the image, occurs at [Line 63 of functions.inc.php](https://github.com/librenms/librenms/blob/master/includes/html/functions.inc.php#L63)\n```php\n$overlib_content = '<div class=overlib><span class=overlib-text>' . $text .
