{"id":"CVE-2024-56144","aliases":["GHSA-2f4w-6mc7-4w78"],"url":"https://o3.security/vulnerability/CVE-2024-56144","summary":"Stored XSS-LibreNMS-Display Name 2 in librenms","details":"# StoredXSS-LibreNMS-Display Name 2\n\n\n**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 24.11.0 ([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 by going to the \"Device Settings\" section.\n3. In the \"Display Name\" field, enter the following payload: `\"><img src onerror=\"alert(document.cookie)\">`.\n![image](https://github.com/user-attachments/assets/b1664e15-eba8-4cdd-b730-fb18936f109c)\n4. Save the changes.\n5. The XSS payload is triggered when navigating to the path /device/$DEVICE_ID/logs and hovering over a type containing a tag (such as Core 1 in the image).\n![image](https://github.com/user-attachments/assets/df23cec8-94bb-4155-961b-52ea659654a2)\n\n\n\n**Impact:**\n\nExecution of Malicious Code","published":"2025-01-16T22:28:03.567Z","modified":"2026-08-12T03:51:18.377626298Z","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":"24.12.0"}],"fix":{"url":"https://github.com/librenms/librenms/pull/16886","label":"librenms/librenms#16886"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56144.json"},{"type":"ADVISORY","url":"https://github.com/librenms/librenms/security/advisories/GHSA-2f4w-6mc7-4w78"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-56144"},{"type":"WEB","url":"https://github.com/librenms/librenms/pull/16886"},{"type":"WEB","url":"https://github.com/librenms/librenms/commit/c63c912d86098bcefd52a28328482b94632eadf8"},{"type":"PACKAGE","url":"https://github.com/librenms/librenms"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:18.377626298Z"}}
