CVE-2025-0692: Low Vulnerability in Maximize Simple Video Management System

The Simple Video Management System WordPress plugin through 1.0.4 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed, for example in a multisite setup. This vulnerability is classified as low in severity, with a CVSS score of 3.5, indicating that while it poses some risk, it may not be immediately exploitable in all scenarios.

Risk to organizations includes potential unauthorized access to sensitive data through stored XSS attacks. Attackers may leverage this vulnerability to inject malicious scripts, affecting the integrity of the application. Organizations should prioritize patching immediately to mitigate these risks.

As of now, there are no known public exploits or active exploitation in the wild. However, given the nature of stored XSS vulnerabilities, it is essential for organizations using this plugin to address the issue promptly.

Organizations should consider applying the necessary patches and implementing additional web application security measures to minimize exposure to similar vulnerabilities in the future.

Vulnerability Details

The Simple Video Management System WordPress plugin through 1.0.4 is affected due to improper sanitization and escaping of settings. This vulnerability allows high privilege users to perform stored Cross-Site Scripting attacks.

The CVSS score of 3.5 classifies this vulnerability as low, indicating that while it has potential impacts on confidentiality and integrity, it does not affect availability. The attack vector is network-based, requiring high privileges and user interaction.

The vulnerability was published on February 13, 2025, and it falls under CWE-79 for improper neutralization of input during web page generation.

Technical Analysis

The root cause of this vulnerability lies in the inadequate sanitization and escaping of user input within the Simple Video Management System plugin. This oversight can lead to stored XSS, where an attacker can inject malicious scripts that are stored and executed in the context of another user's session.

The attack vector is network-based, which means that an attacker can exploit this vulnerability remotely. The attack complexity is considered low due to the straightforward nature of the attack method, while high privileges are required for the attacker to successfully execute the attack.

User interaction is required, as the attack generally involves tricking the victim into executing the injected script. The impacts on confidentiality and integrity are assessed as low, as the attack primarily targets the user’s session without affecting system availability.

Risk & Impact Analysis

Real-world deployment risk exists, especially in environments where high privilege users have access to the plugin. As this vulnerability allows attackers to execute scripts in the context of another user, it can lead to data theft, session hijacking, or further exploitation of the application.

The urgency for organizations to address this vulnerability is moderate. With a CVSS score of 3.5, it is classified as low severity, but organizations should still schedule remediation in their patch cycles to prevent potential exploitation.

Given that this vulnerability is not currently known to be actively exploited, organizations should remain vigilant and monitor for any changes in its status.

Exploitation Status

Affected Versions

The affected version of the Simple Video Management System plugin is all versions prior to vendor patch version 1.0.4. Organizations should ensure they are running the latest version to protect against this vulnerability.

Mitigation & Remediation

To mitigate this vulnerability, organizations should update the Simple Video Management System plugin to the latest version available. If immediate patching is not possible, consider implementing input validation and sanitization measures to prevent XSS attacks.

Organizations can also strengthen their security posture by employing web application firewalls (WAFs) to filter out malicious input and monitoring for unusual activity within their applications. Regular security assessments, such as penetration testing, can help identify and remediate similar vulnerabilities.

Detection Guidance

To detect potential exploitation of this vulnerability, organizations should monitor application logs for unusual script execution or user interactions that seem suspicious. Look for indicators of XSS, such as unexpected HTML or JavaScript code in user input fields.

Behavioral anomalies in user sessions, especially for high privilege users, should be closely monitored. Additionally, tracking network signatures associated with known XSS attacks can provide further detection capabilities.

AppSecure Threat Intelligence Insight

The long-term significance of this vulnerability highlights the importance of proper input validation in web applications. As web applications become increasingly complex, security teams must adopt proactive measures to secure their applications against vulnerabilities like this.

The pattern this vulnerability represents is a common oversight in software development, where the sanitization of user input is often overlooked. Security teams should prioritize secure coding practices and regular code reviews to identify such issues early.

The strategic defensive takeaway is to integrate security into the software development lifecycle (SDLC), ensuring that security measures are in place from the design phase through to deployment. Regularly updating applications and conducting thorough security assessments, such as application security assessments, can significantly reduce the risk of similar vulnerabilities in future releases.

Furthermore, organizations should remain vigilant about emerging threats and continuously improve their security posture to adapt to an evolving threat landscape.
