{"id":"GHSA-2f4w-6mc7-4w78","aliases":["CVE-2024-56144"],"title":"LibreNMS Display Name 2 Stored Cross-site Scripting vulnerability","titleSource":"OSV","descriptionSource":"OSV","declaredSeverity":"MODERATE","description":"# 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Code","severity":"medium","score":4.6,"published":"2025-01-16T17:18:32.000Z","modified":"2025-04-28T18:32:57.000Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"librenms/librenms","sources":[{"name":"OSV · GHSA-2f4w-6mc7-4w78","url":"https://osv.dev/vulnerability/GHSA-2f4w-6mc7-4w78"}],"ranges":[{"events":[{"introduced":"24.11.10"},{"fixed":"24.12.0"}],"type":"ECOSYSTEM"}],"versions":["24.11.10"],"fixed":["24.12.0"]}],"sourceAffected":[],"references":["https://github.com/librenms/librenms/security/advisories/GHSA-2f4w-6mc7-4w78","https://nvd.nist.gov/vuln/detail/CVE-2024-56144","https://github.com/librenms/librenms/pull/16886","https://github.com/librenms/librenms/commit/c63c912d86098bcefd52a28328482b94632eadf8","https://github.com/librenms/librenms"],"sources":[{"name":"OSV","id":"GHSA-2f4w-6mc7-4w78","modified":"2025-04-28T18:32:57Z","url":"https://osv.dev/vulnerability/GHSA-2f4w-6mc7-4w78"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N","score":4.6}],"products":[],"remediation":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T19:15:31.108Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
