CVE-2025-67170 identifies a reflected cross-site scripting (XSS) vulnerability in RiteCMS version 3.1.0. Reflected XSS occurs when untrusted user input is immediately returned by a web application without proper sanitization, allowing an attacker to inject malicious scripts into the victim's browser context. In this case, an attacker crafts a specially designed URL or payload that, when clicked by a user, executes arbitrary JavaScript code within the user's browser session. This can lead to theft of session cookies, defacement, or redirection to malicious sites. The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-20 (Improper Input Validation), indicating that RiteCMS fails to adequately validate or encode user input before reflecting it in the web page. The CVSS vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) indicates that the attack can be launched remotely over the network without privileges, requires low attack complexity, no privileges, but does require user interaction. The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component, potentially impacting the user's browser environment. The impact on confidentiality and integrity is low to moderate, as attackers can steal sensitive information or manipulate content but cannot disrupt service availability. No patches or known exploits are currently available, suggesting the vulnerability is newly disclosed. Organizations using RiteCMS 3.1.0 should prioritize remediation once patches are released and consider interim mitigations.

For European organizations, the reflected XSS vulnerability in RiteCMS 3.1.0 poses a risk primarily to web application users, including employees, customers, and partners. Exploitation could lead to session hijacking, credential theft, or unauthorized actions performed in the context of the victim’s browser session, potentially exposing sensitive corporate or personal data. This can undermine user trust and lead to reputational damage, regulatory non-compliance (e.g., GDPR concerns regarding data protection), and financial losses. Since RiteCMS is a content management system, websites hosting critical business information or customer portals are at risk. The vulnerability does not directly affect system availability but can be leveraged as a stepping stone for further attacks or social engineering campaigns. European organizations with public-facing RiteCMS installations should be particularly vigilant, as attackers may target these to gain footholds or harvest user credentials. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, especially as proof-of-concept exploits may emerge.

1. Implement strict input validation and output encoding on all user-supplied data within RiteCMS to prevent injection of malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3. Educate users and staff about the risks of clicking suspicious links, especially those received via email or social media. 4. Monitor web server logs and application behavior for unusual requests or patterns indicative of attempted XSS exploitation. 5. Isolate critical web applications and limit the scope of user privileges to reduce impact if exploitation occurs. 6. Apply web application firewalls (WAFs) with rules tailored to detect and block reflected XSS payloads targeting RiteCMS. 7. Stay informed about official patches or updates from RiteCMS developers and apply them promptly once available. 8. Conduct regular security assessments and penetration testing focused on web application vulnerabilities. 9. Consider temporary disabling or restricting features that reflect user input until a patch is released. 10. Use multi-factor authentication to reduce the impact of stolen credentials resulting from XSS attacks.
