CVE-2024-34061 Scanner

Changedetection.io is commonly used by individuals and organizations alike who need to track changes on specific web pages. It's popular among e-commerce enthusiasts tracking product restocks, news agencies monitoring for breaking news updates, and businesses overseeing competitor activities. Users rely on Changedetection.io's robust notification system to receive alerts about web changes, aiding in decision-making processes. This software can be deployed both locally and on cloud platforms, making it versatile for different user needs. With easy integration for various notification services, it fits seamlessly into existing workflows. Regular updates and an active community maintain its relevance and security.

Cross-Site Scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages which are then executed in the browsers of unsuspecting users. This particular XSS vulnerability in Changedetection.io involves the 'notification_urls' parameter, where unfiltered user input can lead to script execution in the application's context. Such vulnerabilities compromise user data, allowing attackers to steal sensitive information or impersonate users. Despite being a reflected XSS, the exploit's implications are significant as it can impact the functionality and security of web applications. Remediation measures should be employed swiftly to mitigate potential exploitation.

The vulnerability resides in the 'notification_urls' parameter, which fails to sanitize user inputs properly before rendering them in the browser. The endpoint in the POST request allows crafting a payload that can execute arbitrary JavaScript code. Attackers can exploit this by manipulating URL parameters without storing them, which makes detecting the exploit more challenging. The inadequate validation check in this backend process makes the application susceptible to any script injected through known URL payloads. Immediate action, such as updating to fixed versions, is recommended to protect against these vulnerabilities.

If exploited, this XSS vulnerability could lead to session hijacking, defacement, or redirection to malicious phishing sites. Attackers would have the ability to perform any action the victim user could on the affected site in an unauthorized manner. It can degrade user confidence and damage an organization's reputation if the exploit is realized publicly. Furthermore, this vulnerability might open doors for more complex attacks leveraging injection points recognized by the exploit. Minimizing this risk requires prompt patching and awareness of the potential security impacts.
