CVE-2024-52473

Vulnerability

Overview The HTML5 Lyrics Karaoke Player plugin for WordPress versions 2.4 and below contains a reflected Cross-Site Scripting (XSS) vulnerability due to improper neutralization of user-supplied input during web page generation. This flaw enables an attacker to inject malicious scripts, such as JavaScript payloads, which are then executed in the context of the victim's browser when a specially crafted request is processed [1].

Exploitation

Prerequisites Exploitation requires user interaction: a privileged user (e.g., an administrator) must click a malicious link, visit a crafted page, or submit a specially designed form. The attacker does not need prior authentication but must convince the target to perform the action. The vulnerability is classified as moderate in severity (CVSS 3.1 base score 7.1) and is expected to be targeted in mass-exploit campaigns, as reflected XSS can be used to attack multiple websites at once regardless of their size or popularity [1].

Impact

Successful exploitation allows an attacker to inject arbitrary HTML and scripts into the affected WordPress site's pages. This can be used to redirect visitors to malicious websites, display unwanted advertisements, or steal sensitive information such as session cookies. The injected script executes when any user visits the compromised page, potentially affecting a large number of site visitors [1].

Mitigation

Status No official patch is publicly available as of the advisory date. The recommended immediate action is to update the plugin if a patched version becomes available. In the interim, site administrators should apply a virtual patch or mitigation rule (e.g., those provided by Patchstack) to block attack attempts. If unable to update, hosting providers or web developers should be consulted for further assistance [1].
