CVE-2025-47613: mojoomla School Management XSS Flaw

CVE-2025-47613 Overview

CVE-2025-47613 is a Reflected Cross-Site Scripting (XSS) vulnerability affecting the mojoomla School Management plugin for WordPress. This vulnerability arises from improper neutralization of user-supplied input during web page generation, allowing attackers to inject malicious scripts that execute in the context of a victim's browser session.

Critical Impact

Attackers can execute arbitrary JavaScript code in victims' browsers, potentially stealing session cookies, credentials, or performing actions on behalf of authenticated users within WordPress administrative interfaces.

Affected Products

• mojoomla School Management plugin versions through 92.0.0
• WordPress installations using the vulnerable School Management plugin
• Any web application utilizing the affected School Management component

Technical Details for CVE-2025-47613

Vulnerability Analysis

This Reflected XSS vulnerability (CWE-79) exists within the mojoomla School Management plugin for WordPress. The vulnerability occurs when user-controlled input is reflected back to the browser without proper sanitization or encoding, allowing an attacker to craft malicious URLs containing JavaScript payloads.

When a victim clicks on a specially crafted link or is redirected to a malicious URL, the injected script executes within the victim's browser session. Since the script runs in the context of the vulnerable WordPress site, it has full access to the page's DOM, cookies, and can perform any action the authenticated user is authorized to perform.

The network-based attack vector requires user interaction (clicking a malicious link), but requires no authentication or special privileges to exploit. The vulnerability can affect resources beyond the vulnerable component's scope, potentially compromising the confidentiality, integrity, and availability of the victim's session and data.

Root Cause

The root cause of this vulnerability is insufficient input validation and output encoding within the School Management plugin. User-supplied data is directly incorporated into the HTML response without proper sanitization, allowing HTML and JavaScript injection. The plugin fails to implement proper security controls such as:

• Input validation to reject or sanitize potentially malicious characters
• Output encoding (HTML entity encoding) when rendering user-supplied data
• Content Security Policy (CSP) headers to mitigate script execution

Attack Vector

This vulnerability is exploitable over the network and requires user interaction. An attacker typically exploits Reflected XSS by:

1. Crafting a malicious URL containing JavaScript payload in a vulnerable parameter
2. Distributing the malicious link via phishing emails, social media, or compromised websites
3. When a victim clicks the link, the malicious script executes in their browser
4. The script can then steal session tokens, capture credentials, or perform unauthorized actions

The attack is particularly dangerous in WordPress environments where administrative users may be targeted, potentially leading to complete site compromise.

Technical details and proof-of-concept information can be found in the Patchstack WordPress Vulnerability Report.

Detection Methods for CVE-2025-47613

Indicators of Compromise

• Unusual URL parameters containing encoded JavaScript or HTML tags in web server access logs
• Requests to the School Management plugin endpoints with suspicious query strings containing <script>, javascript:, onerror=, or similar XSS payloads
• Browser console errors or unexpected script execution on School Management pages
• Reports of phishing emails containing links to your WordPress site with long, encoded URL parameters

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common XSS payload patterns in requests
• Implement log analysis to identify requests containing encoded script tags or event handlers in URL parameters
• Use browser-based XSS detection tools and Content Security Policy (CSP) violation reporting
• Monitor for unusual access patterns to School Management plugin endpoints

Monitoring Recommendations

• Enable detailed access logging for WordPress and specifically monitor requests to /wp-content/plugins/school-management/ paths
• Configure CSP reporting to capture and alert on policy violations that may indicate XSS attempts
• Implement real-time alerting for requests matching known XSS patterns
• Review authentication logs for suspicious session activity following potential XSS exploitation

How to Mitigate CVE-2025-47613

Immediate Actions Required

• Update the mojoomla School Management plugin to a version newer than 92.0.0 once a patch is available
• Implement Content Security Policy (CSP) headers to restrict script execution to trusted sources
• Deploy Web Application Firewall rules to filter malicious input patterns
• Review and audit any user input handling in custom implementations using the plugin
• Consider temporarily disabling the plugin if a patch is not available and the risk is unacceptable

Patch Information

Organizations should monitor the Patchstack WordPress Vulnerability Report and the official mojoomla plugin repository for updated versions that address this vulnerability. Apply the security update as soon as it becomes available.

Workarounds

• Implement a Web Application Firewall (WAF) with XSS protection rules as a compensating control
• Add Content Security Policy headers to your WordPress site to mitigate the impact of XSS attacks
• Restrict access to the School Management plugin to trusted IP addresses if possible
• Educate users about phishing attacks and suspicious links pointing to your WordPress installation

# WordPress .htaccess CSP header configuration example
<IfModule mod_headers.c>
    Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline';"
    Header set X-XSS-Protection "1; mode=block"
    Header set X-Content-Type-Options "nosniff"
</IfModule>
