WordPress vulnerability analysis and mitigation

The Ibtana – WordPress Website Builder plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2023-6684) in versions up to and including 1.2.2. The vulnerability was discovered and reported by István Márton, with the initial disclosure made on December 7, 2023. The issue affects the plugin's 'ive' shortcode functionality (Wordfence Advisory).

The vulnerability stems from insufficient input sanitization and output escaping of the 'width' and 'height' user-supplied attributes in the 'ive' shortcode. The issue has been assigned a CVSS v3.1 base score of 5.4 (Medium) by NIST with a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, while Wordfence assessed it at 6.4 (Medium) with a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N. The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) (NVD).

When exploited, this vulnerability allows authenticated attackers with contributor level permissions or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever any user accesses the compromised page, potentially leading to session hijacking, credential theft, or other client-side attacks (WPScan).

The vulnerability has been patched in version 1.2.2.1 of the Ibtana – WordPress Website Builder plugin. Site administrators are strongly advised to update to this version or later to mitigate the security risk (WPScan).
