CVE-2025-30902 is a reflected Cross-site Scripting (XSS) vulnerability in ATL Software SRL's AEC Kiosque product, versions up to 1.9.3. The issue stems from improper neutralization of input during web page generation, which allows attackers to inject malicious scripts that execute in users' browsers when they visit crafted URLs or pages. This can lead to partial compromise of confidentiality, integrity, and availability of affected systems or user sessions. The vulnerability has a CVSS 3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability. No patch or official remediation guidance is currently provided by the vendor.

Successful exploitation of this reflected XSS vulnerability can allow attackers to execute arbitrary scripts in the context of a victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. The CVSS score of 7.1 reflects a high severity with partial impact on these security properties. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider applying web application firewall (WAF) rules to detect and block reflected XSS attempts and educate users to avoid clicking suspicious links. Monitor vendor communications for updates and apply patches promptly once released.
