CVE-2024-52470

Vulnerability

Overview CVE-2024-52470 is a reflected Cross-Site Scripting (XSS) vulnerability in the WordPress Dynamic URL SEO plugin, versions 1.0 and earlier. The plugin fails to properly neutralize input during web page generation, allowing malicious scripts to be injected via crafted URLs [1]. This is a classic improper neutralization issue (CWE-79).

Exploitation

Requirements An unauthenticated attacker can craft a malicious link containing the XSS payload. Successful exploitation requires a privileged user (e.g., an admin) to click the link, visit a crafted page, or submit a form [1]. No authentication is needed for the attacker, but the victim must be authenticated and perform an action.

Impact

If exploited, the attacker can inject arbitrary HTML and JavaScript, which may execute in the context of the victim's session. This could lead to redirects, ad injection, theft of cookies, or other malicious actions on the affected WordPress site [1].

Mitigation

The vulnerability has a CVSS score of 7.1 (High). The vendor released version 1.2 as a fix. Users should update immediately. For those unable to update, Patchstack offers a virtual mitigation rule [1]. The vulnerability is considered moderately dangerous and is expected to be used in mass-exploit campaigns targeting thousands of sites.
