The vulnerability identified as CVE-2015-4582 affects TheCartPress boot-store theme version 1.6.4 for WordPress, representing a cross-site scripting flaw that specifically targets the header.php file within the theme's tcp_register_error implementation. This issue falls under the category of stored cross-site scripting vulnerabilities, where malicious input can be executed in the context of other users' browsers when they view affected pages. The vulnerability stems from insufficient input validation and output encoding within the theme's registration error handling mechanism, creating an avenue for attackers to inject malicious scripts that persist in the system and execute whenever legitimate users access the affected theme components.
The technical exploitation of this vulnerability occurs through the manipulation of user input parameters that are processed by the tcp_register_error function in the header.php file. When users register or encounter registration errors within the WordPress environment utilizing this theme, the error messages are not properly sanitized or encoded before being rendered in the HTML output. This allows attackers to inject malicious JavaScript code that gets executed in the browser context of other users who view the affected pages. The vulnerability is particularly concerning because it operates in a persistent manner, as the stored error messages remain in the system until actively removed, making it a long-term threat to users of the affected WordPress installation.
The operational impact of CVE-2015-4582 extends beyond simple script execution, as it can enable attackers to perform various malicious activities including session hijacking, credential theft, defacement of the affected website, or redirection to malicious sites. The vulnerability affects the core WordPress theme functionality and can compromise the integrity of user sessions, potentially allowing unauthorized access to administrative panels or user accounts. Given that WordPress themes are widely deployed across numerous websites, this vulnerability creates a significant risk for organizations that have not updated to patched versions or have not implemented additional security measures to mitigate such threats.
Security professionals should note that this vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications, and demonstrates how theme-level vulnerabilities can create attack vectors within WordPress ecosystems. The ATT&CK framework categorizes this as a code injection technique, specifically within the application layer, where attackers leverage weaknesses in input validation to execute malicious code. Organizations should implement comprehensive security measures including regular theme updates, input validation enforcement, and output encoding practices to prevent such vulnerabilities from being exploited. The lack of Oracle product association confirms that this is a third-party WordPress theme vulnerability that requires direct attention from WordPress site administrators rather than Oracle security teams, emphasizing the importance of maintaining up-to-date third-party components in web security hygiene practices.
