CVE-2024-13630 Scanner

NewsTicker is a WordPress plugin used by web administrators and content managers to create and display news tickers on websites. It is primarily utilized to disseminate timely information or highlight updates across the website's frontend. The plugin is popular among users who require a dynamic method to present news and important notifications attractively. Given its integration capabilities, it is favored in WordPress installations that emphasize content delivery and user engagement. The plugin's versatility makes it a commonly deployed tool in various themes and configurations in the WordPress ecosystem. Recent versions have aimed at enhancing user experience by integrating broader customization options and performance improvements.

The vulnerability identified in the NewsTicker plugin is a Reflected Cross-Site Scripting (XSS) flaw. It arises due to improper sanitization and escaping of input parameters before they are output on the page. This weakness allows attackers to execute arbitrary scripts in the context of a high privilege user's session if the user clicks on a crafted, malicious link. Such execution can facilitate a range of malicious activities including session hijacking and escalating privileges within the affected application. As it affects high privilege users, mitigating this vulnerability is crucial for maintaining the integrity and security of the website.

Technically, the vulnerability is embedded in the 'update_news' endpoint of the plugin's administration section. When certain parameters are not properly sanitized, an attacker can inject scripts through crafted input passed via GET requests. The vulnerability is particularly concerning as it co-opts the WordPress admin area, exploiting lack of input validation and escaping mechanisms. Exploitation involves sending a specially crafted URL to an authenticated user, which, when accessed, executes the injected script. The vulnerable parameter is part of the URL query string, making it susceptible to direct manipulation for malicious purposes.

If exploited, this XSS vulnerability could lead to significant security issues for websites using vulnerable versions of NewsTicker. Attacks exploiting this flaw may result in hijacked user sessions, unauthorized actions performed under high privilege, and exposure of sensitive information. Additionally, it can facilitate further attacks such as installation of malware or clandestine addition of backdoors. The potential impacts emphasize the importance of addressing this vulnerability promptly to prevent unauthorized access and data breaches.
