CVE-2024-1935 is a stored cross-site scripting (XSS) vulnerability classified under CWE-80, affecting the WordPress plugin 'Giveaways and Contests by RafflePress – Get More Website Traffic, Email Subscribers, and Social Followers' developed by smub. The vulnerability exists in all plugin versions up to and including 1.12.5 due to insufficient sanitization and escaping of the 'parent_url' parameter. This flaw allows unauthenticated attackers to inject arbitrary JavaScript code into web pages generated by the plugin. When a user accesses a page containing the injected script, the malicious code executes in the context of the victim's browser, potentially leading to session hijacking, credential theft, or unauthorized actions performed with the victim's privileges. The vulnerability has a CVSS 3.1 base score of 7.2, indicating high severity, with an attack vector of network (remote exploitation), low attack complexity, no privileges required, and no user interaction needed. The scope is changed (S:C), meaning the vulnerability affects components beyond the vulnerable plugin itself, impacting confidentiality and integrity but not availability. No patches or exploit code are currently publicly available, but the risk remains significant due to the plugin's popularity and the ease of exploitation. The vulnerability highlights the critical need for proper input validation and output encoding in web applications, especially those handling user-supplied data in dynamic web content.

The impact of CVE-2024-1935 on organizations worldwide can be substantial. Exploitation of this stored XSS vulnerability allows attackers to execute arbitrary scripts in the browsers of users visiting affected sites, leading to theft of sensitive information such as authentication tokens, cookies, and personal data. This can result in account takeover, unauthorized access to user accounts, and potential lateral movement within organizational networks if administrative users are targeted. The integrity of user interactions and data can be compromised, undermining trust in the affected websites and potentially causing reputational damage. While availability is not directly impacted, the indirect consequences of data breaches and compromised user accounts can lead to service disruptions and increased incident response costs. Given that the vulnerability requires no authentication or user interaction, it is highly accessible to attackers, increasing the likelihood of exploitation. Organizations relying on the affected plugin for marketing and user engagement must act swiftly to mitigate risks and protect their users.

To mitigate CVE-2024-1935 effectively, organizations should: 1) Immediately update the 'Giveaways and Contests by RafflePress' plugin to a patched version once available; if no patch exists, consider temporarily disabling the plugin to prevent exploitation. 2) Implement strict input validation on the 'parent_url' parameter to reject or sanitize any suspicious input before processing. 3) Apply context-aware output encoding/escaping to all user-supplied data rendered in web pages to prevent script injection. 4) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 5) Monitor web server and application logs for unusual requests or payloads targeting the vulnerable parameter. 6) Educate site administrators and developers on secure coding practices and the importance of timely updates. 7) Conduct regular security assessments and penetration testing focusing on input handling and output encoding. 8) Use Web Application Firewalls (WAFs) with rules designed to detect and block XSS payloads targeting this plugin. These measures, combined, will reduce the attack surface and protect users from exploitation until a permanent fix is deployed.
