CVE-2025-52782 is a high-severity reflected Cross-site Scripting (XSS) vulnerability affecting the King Rayhan Scroll UP product, versions up to 2.0. The vulnerability arises from improper neutralization of input during web page generation, classified under CWE-79. Specifically, the Scroll UP component fails to adequately sanitize user-supplied input before incorporating it into dynamically generated web pages. This flaw allows an attacker to craft malicious URLs or input parameters that, when processed by the vulnerable application, cause the injection and execution of arbitrary JavaScript code in the context of the victim's browser. The vulnerability is exploitable remotely over the network without requiring any privileges or authentication, but it does require user interaction, such as clicking a malicious link. The CVSS 3.1 base score of 7.1 reflects its high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but user interaction needed (UI:R). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component, impacting confidentiality, integrity, and availability to a limited extent (C:L, I:L, A:L). While no known exploits are currently reported in the wild, the vulnerability presents a significant risk due to the potential for session hijacking, credential theft, or delivery of further malware through browser-based attacks. The lack of available patches at the time of publication increases the urgency for mitigation. Scroll UP is a web interface enhancement tool, often integrated into websites to provide smooth scrolling features, which suggests that affected installations are likely web-facing and accessible to external users.

For European organizations, the reflected XSS vulnerability in King Rayhan Scroll UP poses a risk primarily to web applications that incorporate this product. Exploitation can lead to theft of session cookies, user credentials, or execution of malicious scripts that compromise user data confidentiality and integrity. This can result in unauthorized access to user accounts, data leakage, and potential reputational damage. Additionally, attackers may leverage the vulnerability to conduct phishing campaigns or deliver malware payloads, impacting availability indirectly through user disruption or system compromise. Organizations in sectors with high web presence such as e-commerce, government portals, and financial services are particularly at risk. Given the vulnerability requires user interaction, social engineering tactics could be employed to maximize impact. The reflected nature of the XSS means that attacks are typically delivered via crafted URLs, which can be disseminated through email or other communication channels. The vulnerability’s scope change indicates that exploitation could affect resources beyond the immediate vulnerable component, potentially impacting broader application functionality or user sessions. The absence of known exploits currently provides a window for proactive mitigation, but the high CVSS score underscores the need for urgent attention.

1. Immediate mitigation should include implementing robust input validation and output encoding on all user-supplied data within the Scroll UP integration points, ensuring that any dynamic content is properly sanitized to neutralize script injection attempts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. 3. Use HTTPOnly and Secure flags on cookies to protect session tokens from being accessed via injected scripts. 4. Monitor web server logs and web application firewall (WAF) alerts for suspicious requests containing script payloads or unusual URL parameters targeting Scroll UP endpoints. 5. Educate users and staff about the risks of clicking on untrusted links, especially those purporting to be from internal or trusted sources. 6. If possible, temporarily disable or replace the Scroll UP component with a secure alternative until an official patch or update is released by King Rayhan. 7. Coordinate with web development teams to review and harden all web application components that interact with Scroll UP, ensuring adherence to secure coding practices. 8. Stay informed on vendor advisories for patch releases and apply updates promptly once available.
