Lifecycle Timeline
2DescriptionCVE.org
Lyrion Music Server 9.2.0 contains an unauthenticated reflected cross-site scripting vulnerability in the server.log endpoint that allows attackers to inject arbitrary HTML and JavaScript code through the search parameter. Attackers can craft malicious URLs with JavaScript payloads in the search parameter to execute code in users' browsers within the context of the affected application.
AnalysisAI
Reflected cross-site scripting in Lyrion Music Server 9.2.0 allows a remote unauthenticated attacker to inject and execute arbitrary JavaScript in a victim's browser by tricking them into visiting a crafted URL targeting the server.log endpoint's search parameter. The vulnerability carries a changed scope (S:C in CVSS), meaning malicious script executes in the context of the affected application's origin, enabling session theft, credential harvesting, or UI redressing against users of the media server interface. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker requires no authentication (PR:N per CVSS vector) and no special privileges on the target system. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.1 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N accurately characterizes the real-world risk profile: the attack is network-reachable and requires no authentication (PR:N), but mandatory user interaction (UI:R) and limited confidentiality/integrity impact keep it out of High/Critical territory. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker identifies a Lyrion Music Server 9.2.0 instance accessible from the internet or a shared network, then crafts a URL embedding a JavaScript payload in the search parameter of the server.log endpoint (e.g., appending ?search=<script>...</script> or an encoded equivalent). The attacker delivers this URL to an authenticated or unauthenticated user of the Lyrion interface via phishing email, forum post, or social engineering; when the victim's browser loads the URL, the server reflects the unsanitized input and the injected script executes in the Lyrion application's origin context, allowing the attacker to steal session cookies, capture credentials, or perform actions on behalf of the victim. … |
| Remediation | No vendor-released patch or fixed version is identified in the available data - the CPE wildcard and absence of a patch reference in either advisory confirm this. … Detailed patch versions, workarounds, and compensating controls in full report. |
