CVE-2024-12438 is a reflected Cross-Site Scripting (XSS) vulnerability identified in the WooCommerce Digital Content Delivery (incl. DRM) – FlickRocket plugin for WordPress, affecting all versions up to and including 4.74. The vulnerability stems from insufficient input sanitization and output escaping of the 'start_date' and 'end_date' URL parameters. This allows unauthenticated attackers to craft malicious URLs containing arbitrary JavaScript code that, when clicked by a victim, executes in the context of the affected website. The attack vector is network-based, requiring no privileges but user interaction (clicking a malicious link). The vulnerability impacts the confidentiality and integrity of user data by potentially enabling theft of session cookies, credentials, or performing actions on behalf of the user. Availability is not impacted. The CVSS 3.1 base score is 6.1, reflecting medium severity. No patches or fixes are currently linked, and no known exploits are reported in the wild. The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation). Given the widespread use of WooCommerce and WordPress globally, this vulnerability poses a risk to many e-commerce sites using the FlickRocket plugin for digital content delivery and DRM. Attackers could leverage this flaw for phishing, session hijacking, or defacement attacks. Mitigation requires prompt updates once patches are available, or applying web application firewall (WAF) rules to sanitize input and block malicious payloads. User education to avoid clicking suspicious links is also important.

The primary impact of CVE-2024-12438 is on the confidentiality and integrity of users interacting with affected WooCommerce sites using the FlickRocket plugin. Successful exploitation can lead to theft of session cookies, user credentials, or execution of arbitrary actions within the victim's session, potentially compromising user accounts and sensitive data. This can facilitate further attacks such as account takeover, unauthorized purchases, or data leakage. Although availability is not directly affected, the reputational damage and loss of customer trust from such attacks can be significant for e-commerce businesses. The vulnerability's exploitation requires user interaction, which may limit large-scale automated attacks but remains a serious risk through phishing campaigns. Organizations worldwide that rely on this plugin for digital content delivery are vulnerable, especially those with high traffic and valuable digital assets. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability is publicly known. Overall, the medium severity rating reflects a moderate but actionable risk that should be addressed promptly.

1. Monitor for official patches or updates from FlickRocket and apply them immediately once available to remediate the vulnerability. 2. In the absence of patches, implement Web Application Firewall (WAF) rules to detect and block malicious payloads targeting the 'start_date' and 'end_date' parameters, focusing on typical XSS attack patterns such as script tags or event handlers. 3. Employ input validation and output encoding at the application level if custom modifications are possible, ensuring that all user-supplied parameters are properly sanitized and escaped before rendering. 4. Use Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected pages, mitigating the impact of reflected XSS. 5. Educate users and staff about the risks of clicking suspicious links, especially those received via email or social media, to reduce the likelihood of successful exploitation. 6. Conduct regular security assessments and penetration testing on e-commerce platforms to detect similar vulnerabilities proactively. 7. Monitor web server and application logs for unusual requests targeting the vulnerable parameters to identify potential exploitation attempts early.
