Executive brief
The miniOrange OTP Verification plugin for WordPress, which provides one-time password security for user logins and forms, is vulnerable to a security flaw that allows attackers to inject malicious scripts into the website. If a site administrator or visitor interacts with a specially crafted link or page, the attacker could potentially hijack user sessions, redirect visitors to malicious websites, or deface the site. This vulnerability can be exploited by remote attackers without needing any login credentials.
Technical details
A Reflected Cross-Site Scripting (XSS) vulnerability exists in the miniOrange OTP Verification plugin for WordPress due to improper neutralization of user-supplied input during web page generation (CWE-79). The flaw allows an unauthenticated remote attacker to inject malicious JavaScript payloads. Exploitation requires a victim (such as a site administrator) to perform an action, such as clicking a malicious link or visiting a crafted URL. Successful exploitation can lead to session hijacking, unauthorized actions in the context of the victim's browser, or the delivery of further web-based attacks. The issue is resolved in version 5.5.2.
