The vulnerability CVE-2025-23724 in University Quizzes Online (versions up to 1.4) is a reflected Cross-site Scripting (XSS) issue caused by improper input neutralization during web page generation. This allows attackers to inject and execute arbitrary scripts in users' browsers when they interact with crafted URLs or inputs. The CVSS 3.1 score of 7.1 indicates a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts to confidentiality, integrity, and availability at low levels.

Successful exploitation of this vulnerability can lead to execution of arbitrary scripts in the context of the victim's browser, potentially resulting in partial disclosure of sensitive information, modification of data, and disruption of application availability. The reflected nature requires user interaction, such as clicking a malicious link. 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 exercise caution when interacting with untrusted inputs or links related to University Quizzes Online. Implementing web application firewall (WAF) rules to detect and block reflected XSS attempts may provide temporary mitigation.
