{"id":"GHSA-pm8j-3v64-92cq","summary":"LibreNMS Display Name Stored Cross-site Scripting vulnerability","details":"**Description:**\n\n\nXSS on the parameters (Replace $DEVICE_ID with your specific $DEVICE_ID value):`/device/$DEVICE_ID/edit` -\u003e param: display\n\n\nof Librenms versions 24.9.0, 24.10.0, and 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**Proof of Concept:**\n1. Add a new device through the LibreNMS interface.\n2. Edit the newly created device by going to the \"Device Settings\" section.\n3. In the \"Display Name\" field, enter the following payload: `\"\u003e\u003cscript\u003ealert(1)\u003c/script\u003e`.\n![Screenshot from 2024-11-06 09-41-37](https://github.com/user-attachments/assets/6b44e049-5748-4f70-a667-c681cacec9da)\n\n4. Save the changes.\n5. The XSS payload triggers when accessing the \"/apps\" path (if an application was previously added).\n![Screenshot from 2024-11-06 09-42-05](https://github.com/user-attachments/assets/4bd39e1e-6c60-4cc5-b922-8db7fc8094fc)\n \n**Additional PoC:**\n1. In the \"Display Name\" field, enter the following payload: `\"\u003e\u003cimg src onerror=\"alert(1)\"\u003e`.\n![image](https://github.com/user-attachments/assets/addb1b00-23b1-4c26-8ac7-494cb24ebe8a)\n\n2. The XSS vulnerability is triggered when accessing the \"/ports\" path, and the payload executes when hovering over the modified value in the \"Port\" field.\n![image](https://github.com/user-attachments/assets/446e0d62-2016-4435-a1eb-fe85079498e4)\n-  on `/device/$DEVICE_ID/ports/arp` path:\n![image](https://github.com/user-attachments/assets/72a42b6d-bef0-46d4-a210-5d4888dd5c89)\n\n- on `/device/$DEVICE_ID/logs` path:\n![image](https://github.com/user-attachments/assets/b1322946-7b84-4190-8f77-9854f5b5925c)\n\n- on `/search/search=arp/` path:\n![image](https://github.com/user-attachments/assets/103297b0-5364-4d12-b519-d74777367a2a)\n\n**Impact:**\n\nExecution of Malicious Code","aliases":["CVE-2025-23198"],"modified":"2025-04-28T19:12:38.330360Z","published":"2025-01-16T17:21:20Z","database_specific":{"cwe_ids":["CWE-79"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2025-01-16T17:21:20Z","nvd_published_at":"2025-01-16T23:15:08Z"},"references":[{"type":"WEB","url":"https://github.com/librenms/librenms/security/advisories/GHSA-pm8j-3v64-92cq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-23198"},{"type":"WEB","url":"https://github.com/librenms/librenms/commit/afe92dbf4321f107012690d476685603d1ccb013"},{"type":"PACKAGE","url":"https://github.com/librenms/librenms"}],"affected":[{"package":{"name":"librenms/librenms","ecosystem":"Packagist","purl":"pkg:composer/librenms/librenms"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"24.9.0"},{"fixed":"24.11.0"}]}],"versions":["24.10.0","24.10.1","24.9.0","24.9.1"],"database_specific":{"last_known_affected_version_range":"\u003c 24.10.1","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/01/GHSA-pm8j-3v64-92cq/GHSA-pm8j-3v64-92cq.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N"}]}
