WordPress vulnerability analysis and mitigation

A Reflected Cross-Site Scripting (XSS) vulnerability was discovered in the Easy Social Share Buttons WordPress plugin, identified as CVE-2024-30196. The vulnerability affects all versions up to and including 9.4 of the plugin. The issue was discovered by Rafie Muhammad and was publicly disclosed on March 25, 2024. The vulnerability stems from insufficient input sanitization and output escaping in the plugin (WPScan).

The vulnerability is classified as a Cross-Site Scripting (CWE-79) issue, specifically an Improper Neutralization of Input During Web Page Generation vulnerability. It has received a CVSS v3.1 base score of 7.1 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L. The vulnerability allows unauthenticated attackers to inject arbitrary web scripts that execute when users perform certain actions (Patchstack).

The vulnerability could allow malicious actors to inject malicious scripts, including redirects, advertisements, and other HTML payloads into the website. These injected scripts would be executed when guests visit the affected site, potentially compromising user security and website integrity (Patchstack).

The vulnerability requires no authentication to exploit and has a low attack complexity. However, it does require user interaction to be successful, as victims need to be tricked into performing specific actions such as clicking on a malicious link (WPScan).

The vulnerability has been fixed in version 9.5 of the Easy Social Share Buttons plugin. Users are advised to update to version 9.5 or later immediately to resolve the vulnerability. Additionally, Patchstack has issued a virtual patch to mitigate this issue by blocking potential attacks until users can update to the fixed version (Patchstack).
