CVE-2024-33924

Vulnerability

The Realtyna Organic IDX plugin for WordPress (versions n/a through 4.14.4) contains a reflected cross-site scripting (XSS) vulnerability due to improper neutralization of user-supplied input during web page generation. This occurs in the plugin's handling of certain parameters, allowing injection of arbitrary HTML and JavaScript. The vulnerability is present in all versions up to and including 4.14.4. [1]

Exploitation

An attacker can exploit this vulnerability by crafting a malicious URL containing a specially crafted query parameter that is not properly sanitized. The victim must be tricked into clicking the link, which then reflects the injected script in the response. No authentication is required, and the attack can be performed remotely over HTTP. [1]

Impact

Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of the victim's browser session. This can lead to theft of sensitive information such as session cookies, redirection to malicious sites, or defacement of the page. The impact is limited to the victim's browser and does not directly compromise the WordPress server. [1]

Mitigation

The vendor has released an updated version (5.2.0) which likely addresses the issue. Users are advised to update to the latest version. If updating is not possible, consider implementing a web application firewall (WAF) rule to block malicious query strings. No workaround is provided in the available reference. [1]
