CVE-2024-10150 in Bamazoo Plugin
Summary
by MITRE • 10/25/2024
The Bamazoo – Button Generator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's dgs shortcode in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Bamazoo Button Generator plugin for WordPress presents a critical stored cross-site scripting vulnerability identified as CVE-2024-10150, affecting all versions up to and including 1.0. This vulnerability resides within the plugin's dgs shortcode functionality and represents a significant security flaw that undermines the integrity of WordPress installations. The vulnerability stems from inadequate input sanitization and insufficient output escaping mechanisms that fail to properly validate or encode user-supplied attributes before processing them within the plugin's shortcode implementation.
The technical flaw manifests when authenticated attackers with contributor-level permissions or higher exploit the insufficient input validation controls within the plugin's shortcode processing. These attackers can inject malicious JavaScript code through the dgs shortcode attributes, which are then stored within the WordPress database and subsequently executed whenever any user accesses pages containing the injected content. The vulnerability operates as a stored XSS attack because the malicious scripts are permanently saved in the application's data storage rather than being reflected in HTTP responses, making the attack persistent and potentially affecting multiple users over time.
The operational impact of this vulnerability extends beyond simple script execution, as it creates a persistent threat vector that can be leveraged for various malicious activities. Attackers could potentially steal user session cookies, redirect victims to phishing sites, deface websites, or establish backdoor access to compromised systems. The contributor-level access requirement means that attackers who have gained access to WordPress accounts with at least contributor privileges can exploit this vulnerability, making it particularly dangerous in environments where multiple users have varying permission levels. This threat is further amplified by the fact that the vulnerability affects all versions up to 1.0, indicating a fundamental flaw in the plugin's design that was never properly addressed.
Security practitioners should immediately implement mitigations including updating to the latest plugin version if available, implementing proper input validation and output escaping mechanisms, and considering the deployment of web application firewalls to detect and block malicious payload attempts. The vulnerability aligns with CWE-79 which describes improper neutralization of input during web page generation, and maps to ATT&CK technique T1566.001 for the initial compromise through the exploitation of web application vulnerabilities. Organizations should also conduct thorough security audits of their WordPress installations to identify any other plugins that may be susceptible to similar vulnerabilities, as this represents a common pattern in WordPress plugin development where security considerations are often overlooked in favor of functionality. The affected plugin's design failure highlights the critical importance of implementing robust input validation and output escaping practices as fundamental security controls to prevent such vulnerabilities from being exploited in production environments.
