{"id":"CVE-2025-23198","aliases":["GHSA-pm8j-3v64-92cq"],"url":"https://o3.security/vulnerability/CVE-2025-23198","summary":"Stored-XSS-LibreNMS-Display-Name in librenms","details":"**Description:**\n\n\nXSS on the parameters (Replace $DEVICE_ID with your specific $DEVICE_ID value):`/device/$DEVICE_ID/edit` -> 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: `\"><script>alert(1)</script>`.\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: `\"><img src onerror=\"alert(1)\">`.\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","published":"2025-01-16T22:26:25.873Z","modified":"2026-08-12T03:51:39.668574386Z","cvss":{"score":4.6,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"librenms/librenms","fixedVersion":"24.11.0"}],"fix":{"url":"https://github.com/librenms/librenms/commit/afe92dbf4321f107012690d476685603d1ccb013","label":"librenms/librenms@afe92db"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/23xxx/CVE-2025-23198.json"},{"type":"ADVISORY","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:39.668574386Z"}}
