CVE-2024-51913

Vulnerability

Overview

The Mapme plugin for WordPress, versions up to and including 1.3.2, contains a stored cross-site scripting (XSS) vulnerability due to improper neutralization of user-supplied input during web page generation [1]. This flaw allows an attacker to inject arbitrary HTML and JavaScript code that is stored on the server and executed when other users view the affected page.

Exploitation

Details

Exploitation requires a privileged user (e.g., an editor or administrator) to perform an action such as clicking a malicious link, visiting a crafted page, or submitting a specially crafted form [1]. The attacker does not need direct access to the site but must convince a user with the necessary privileges to trigger the payload. The vulnerability is classified as stored XSS, meaning the injected script persists and affects all visitors to the compromised page.

Impact

Successful exploitation allows an attacker to execute arbitrary scripts in the context of the victim's browser. This can be used to redirect users to malicious sites, display advertisements, steal session cookies, or perform other actions that compromise the integrity and confidentiality of the website and its visitors [1]. The CVSS v3 base score is 6.5 (Medium), reflecting the need for user interaction and the potential for widespread impact.

Mitigation

The vendor has not released a patched version as of the publication date. Users are strongly advised to update the plugin immediately if a fix becomes available. If updating is not possible, website administrators should consider disabling the plugin or implementing a web application firewall (WAF) to block malicious payloads [1]. Given that such vulnerabilities are often targeted in mass-exploit campaigns, prompt action is recommended.
