CVE-2024-0283: Kashipara Food Management System XSS Flaw

CVE-2024-0283 Overview

A Cross-Site Scripting (XSS) vulnerability has been identified in Kashipara Food Management System up to version 1.0. This vulnerability exists in the party_details.php file where improper sanitization of the party_name parameter allows attackers to inject malicious scripts. The vulnerability can be exploited remotely and requires user interaction, making it a reflected XSS attack that could compromise user sessions and sensitive data.

Critical Impact

Remote attackers can inject malicious scripts through the party_name parameter, potentially stealing user credentials, session tokens, or redirecting users to malicious websites. The exploit has been publicly disclosed, increasing the risk of active exploitation.

Affected Products

• Kashipara Food Management System up to version 1.0
• WordPress installations using Kashipara Food Management System plugin

Technical Details for CVE-2024-0283

Vulnerability Analysis

This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting (XSS). The flaw resides in the party_details.php file where user-supplied input through the party_name parameter is not properly sanitized before being rendered in the web page output.

When a user submits data containing JavaScript code through the party_name field, the application fails to encode or filter the malicious content, allowing the script to execute in the context of the victim's browser session. This can lead to theft of authentication cookies, session hijacking, defacement of the web page, or redirection to phishing sites.

The vulnerability requires user interaction to exploit—typically through social engineering where an attacker tricks a victim into clicking a malicious link containing the XSS payload.

Root Cause

The root cause of this vulnerability is the absence of proper input validation and output encoding in the party_details.php file. The application directly incorporates user-supplied data from the party_name parameter into the HTML response without sanitizing special characters such as <, >, ", and '. This allows attackers to break out of the intended HTML context and inject arbitrary JavaScript code.

Attack Vector

The attack is initiated remotely over the network. An attacker crafts a malicious URL containing JavaScript payload in the party_name parameter and distributes it to potential victims through phishing emails, social media, or other channels. When a victim clicks the link and the page loads, the injected script executes in their browser with the same privileges as the legitimate application, enabling the attacker to perform actions on behalf of the authenticated user.

The vulnerability documentation and proof-of-concept details are available through the GitHub Vulnerability Report and VulDB Entry #249838.

Detection Methods for CVE-2024-0283

Indicators of Compromise

• Unusual HTTP requests to party_details.php containing JavaScript code or HTML tags in the party_name parameter
• Web server access logs showing URL-encoded script tags such as %3Cscript%3E in query strings
• User reports of unexpected browser behavior or pop-ups when accessing party details functionality
• Session anomalies indicating potential cookie theft or unauthorized access

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common XSS payloads in the party_name parameter
• Monitor HTTP request logs for suspicious patterns including <script>, javascript:, onerror=, and other common XSS vectors
• Deploy browser-based Content Security Policy (CSP) violation reporting to identify attempted script injections
• Use automated vulnerability scanners to regularly test the party_details.php endpoint for XSS vulnerabilities

Monitoring Recommendations

• Enable detailed logging for all requests to party_details.php and related endpoints
• Set up alerts for requests containing HTML special characters or JavaScript keywords in form parameters
• Monitor for unusual user session activity that may indicate session hijacking following XSS exploitation
• Review application error logs for encoding or rendering errors that may indicate injection attempts

How to Mitigate CVE-2024-0283

Immediate Actions Required

• Implement input validation to restrict the party_name parameter to alphanumeric characters and safe special characters only
• Apply output encoding (HTML entity encoding) to all user-supplied data before rendering in HTML context
• Deploy Content Security Policy (CSP) headers to prevent inline script execution
• Consider taking the affected functionality offline until a proper patch is available

Patch Information

No official vendor patch has been identified at the time of this analysis. Organizations using Kashipara Food Management System should contact the vendor for security updates or apply the workarounds described below. Monitor the VulDB entry for updates on patch availability.

Workarounds

• Implement server-side input sanitization by stripping or encoding HTML special characters from the party_name parameter
• Add a Web Application Firewall (WAF) rule to block requests containing script tags or JavaScript event handlers
• Implement strict Content Security Policy headers with script-src 'self' to prevent inline script execution
• Restrict access to the party_details.php functionality to authenticated and trusted users only

# Example Apache mod_security rule to block XSS attempts
SecRule ARGS:party_name "@rx (?i)(<script|javascript:|on\w+\s*=)" \
    "id:1001,phase:2,deny,status:403,msg:'XSS attempt blocked in party_name parameter'"

# Example Content Security Policy header configuration
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none';"
