CVE-2025-48098 is a Stored Cross-Site Scripting (XSS) vulnerability identified in Ays Pro Survey Maker, a web-based survey creation platform. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows malicious actors to inject and store arbitrary JavaScript code within the application. When other users access the affected survey pages, the injected scripts execute in their browsers under the context of the vulnerable domain. This can lead to session hijacking, theft of sensitive information, unauthorized actions on behalf of users, or defacement of survey content. The vulnerability affects all versions up to and including 5.1.8.8. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), the attack can be performed remotely over the network without privileges, requires low attack complexity, no authentication, but does require user interaction (e.g., visiting a maliciously crafted survey). The scope is changed, indicating that the vulnerability can affect components beyond the initially vulnerable module. The impact includes partial loss of confidentiality, integrity, and availability. No patches or exploit code are currently publicly available, but the vulnerability is published and should be considered a high risk. The lack of CWE specifics suggests the vulnerability is straightforward XSS due to insufficient input sanitization or output encoding in the survey maker's web interface.

For European organizations using Ays Pro Survey Maker, this vulnerability poses a significant risk to the confidentiality and integrity of survey data and user sessions. Attackers exploiting the stored XSS can hijack user sessions, steal credentials or personal data, manipulate survey results, or deliver malware through the victim's browser. This can lead to reputational damage, regulatory non-compliance (e.g., GDPR violations due to data leakage), and operational disruptions. Organizations relying on survey data for decision-making or customer engagement may face data integrity issues. The vulnerability's remote exploitability without authentication increases the attack surface, especially for public-facing surveys. Additionally, the scope change indicates potential impact beyond the survey module, possibly affecting other integrated systems or user roles. Although no active exploits are known, the high CVSS score and ease of exploitation warrant immediate attention to prevent targeted attacks or automated exploitation campaigns.

1. Apply patches or updates from Ays Pro as soon as they become available to address the vulnerability directly. 2. In the absence of patches, implement strict input validation and output encoding on all user-supplied data fields within the survey maker to neutralize malicious scripts. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the survey platform. 4. Conduct regular security audits and penetration testing focusing on web application input handling and output rendering. 5. Educate users and administrators about the risks of clicking on untrusted survey links and recognizing suspicious content. 6. Monitor web server and application logs for unusual activity or injection attempts. 7. Consider isolating the survey maker environment or restricting access to trusted users until the vulnerability is remediated. 8. Use web application firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting the survey maker endpoints.
