CVE-2024-52349 identifies a DOM-based Cross-site Scripting (XSS) vulnerability in the Awesome Tool Tip plugin authored by Md. Shiddikur Rahman. This vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, specifically within the plugin's JavaScript handling of tooltip content. When a vulnerable version (up to 1.0) of the plugin is installed on a website, an attacker can craft a malicious URL or input that injects executable JavaScript code into the victim's browser environment. Because the vulnerability is DOM-based, the malicious script executes entirely on the client side without server-side sanitization, making traditional server-side protections ineffective. Exploitation does not require authentication, meaning any visitor to a compromised or maliciously crafted page can be affected. The consequences of successful exploitation include theft of session cookies, redirection to malicious sites, or unauthorized actions performed on behalf of the user. No CVSS score has been assigned yet, and no official patches or updates have been released at the time of this report. The vulnerability was published on November 18, 2024, and is currently in a published state with no known active exploits in the wild. The plugin is commonly used in web environments where enhanced tooltip functionality is desired, often integrated into content management systems like WordPress. The lack of input sanitization in the plugin's JavaScript code is the root cause, highlighting the importance of secure coding practices in client-side scripting.

The impact of CVE-2024-52349 is significant for organizations that use the Awesome Tool Tip plugin on their websites. Successful exploitation can lead to the execution of arbitrary JavaScript in the context of the user's browser, compromising confidentiality by exposing session tokens, cookies, and other sensitive information. Integrity can be undermined by allowing attackers to manipulate webpage content or perform unauthorized actions on behalf of users. Availability impact is generally low but could be indirectly affected if attackers deface websites or disrupt user sessions. Because the vulnerability is client-side and requires no authentication, it can be exploited by any attacker who can lure users to a maliciously crafted URL or page. This broadens the attack surface and increases the likelihood of successful attacks, especially in environments with high user traffic. Organizations risk reputational damage, data breaches, and potential regulatory penalties if user data is compromised. The absence of a patch increases exposure time, making proactive mitigation critical. The threat is particularly relevant for websites targeting consumers or users in sectors where trust and data privacy are paramount, such as e-commerce, finance, and healthcare.

To mitigate CVE-2024-52349, organizations should first identify whether they are using the Awesome Tool Tip plugin and determine the version in use. Until an official patch is released, immediate steps include disabling or removing the plugin to eliminate the attack vector. If removal is not feasible, implement Content Security Policy (CSP) headers to restrict the execution of inline scripts and untrusted sources, reducing the risk of script injection. Web application firewalls (WAFs) can be configured to detect and block suspicious input patterns related to XSS attacks targeting this plugin. Developers should review and sanitize all user inputs on the client side, employing secure JavaScript coding practices such as encoding output and avoiding direct insertion of untrusted data into the DOM. Monitoring web traffic and logs for unusual activity or exploitation attempts is also recommended. Once a vendor patch becomes available, prioritize timely updates. Additionally, educating users about the risks of clicking on untrusted links can reduce the likelihood of successful exploitation. For organizations with high security requirements, consider deploying browser isolation or endpoint protection solutions that can mitigate the impact of client-side script execution.
