A cross-site scripting (xss) vulnerability exists in the LoginWordPress loginForm cancelUri parameter functionality of WWBN AVideo 14
AI Analyst Comment
Remediation
Apply vendor security updates immediately. Monitor for exploitation attempts and review access logs.
Executive Summary:
A high-severity Cross-Site Scripting (XSS) vulnerability has been identified in WWBN AVideo software, affecting the login functionality. An attacker can exploit this flaw by tricking a user into clicking a specially crafted link, which could lead to the theft of session credentials, unauthorized actions on the user's behalf, and potential compromise of sensitive data. Immediate patching is required to mitigate the significant risk to the organization's data and user accounts.
Vulnerability Details
CVE-ID: CVE-2025-36548
Affected Software: WWBN Multiple Products
Affected Versions: AVideo version 14. See vendor advisory for a specific list of all affected products and versions.
Vulnerability: This is a reflected Cross-Site Scripting (XSS) vulnerability. The
cancelUriparameter within theloginFormof the LoginWordPress plugin does not properly sanitize user-supplied input. An attacker can craft a malicious URL containing arbitrary JavaScript code within this parameter and send it to a victim. When the victim clicks the link, the malicious script is "reflected" from the URL and executed within the security context of the victim's browser on the trusted AVideo domain, allowing the attacker to bypass standard browser security controls.Business Impact
This vulnerability is rated as High severity with a CVSS score of 8.3. Successful exploitation could have a significant business impact, including the compromise of user and administrator accounts. An attacker could steal session cookies to hijack active sessions, perform actions on behalf of the compromised user, redirect users to malicious websites for phishing attacks, or deface the web application. The theft of an administrator's session could lead to a full compromise of the AVideo platform, resulting in data breaches, service disruption, and severe reputational damage.
Remediation Plan
Immediate Action: Apply the security updates released by WWBN to all affected AVideo instances immediately. After patching, it is critical to monitor for any post-remediation exploitation attempts and review historical web server and application access logs for indicators of compromise.
Proactive Monitoring: Security teams should actively monitor web server logs for requests to the login form that contain suspicious strings or script tags (e.g.,
<script>,onerror,onload) within thecancelUriparameter. Implement alerts for unusual patterns of requests targeting this specific functionality. Network traffic should be monitored for unexpected outbound connections from clients interacting with the application.Compensating Controls: If patching cannot be performed immediately, implement a Web Application Firewall (WAF) rule to inspect and block requests containing XSS payloads in the
cancelUriparameter. Enforce Content Security Policy (CSP) headers on the web server to restrict the execution of inline scripts, which can help mitigate the impact of an XSS attack.Exploitation Status
Public Exploit Available: False
Analyst Notes: As of July 24, 2025, there are no known public exploits or active exploitation campaigns targeting this vulnerability. However, the details provided in the public disclosure are sufficient for skilled attackers to develop a working exploit. Given the high CVSS score, it is likely that threat actors will begin scanning for and attempting to exploit vulnerable systems. This vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities (KEV) Catalog.
Analyst Recommendation
Due to the high severity (CVSS 8.3) of this vulnerability and its potential for account compromise, we strongly recommend that organizations prioritize the immediate application of the vendor-supplied security patch. The risk of session hijacking and data theft is substantial. While this CVE is not yet on the CISA KEV list, its public nature and high impact make it an attractive target for attackers. Patching should be the primary response, followed by the implementation of proactive monitoring and compensating controls to ensure a robust defense-in-depth security posture.
