CVE-2025-7760: Association Web Package Flora XSS Vulnerability

CVE-2025-7760 Overview

CVE-2025-7760 is a Cross-Site Scripting (XSS) vulnerability affecting the Ofisimo Web-Based Software Technologies Association Web Package Flora. This vulnerability allows attackers to inject malicious scripts through HTTP headers, potentially compromising user sessions and sensitive data within the web application.

Critical Impact

Attackers can exploit HTTP header injection to execute arbitrary JavaScript in the context of victim browsers, enabling session hijacking, credential theft, and unauthorized actions on behalf of authenticated users.

Affected Products

• Ofisimo Association Web Package Flora v3.0
• Ofisimo Association Web Package Flora versions through 03022026

Note: The vendor was contacted early about this disclosure but did not respond in any way.

Technical Details for CVE-2025-7760

Vulnerability Analysis

This vulnerability stems from improper neutralization of input during web page generation (CWE-79). The Association Web Package Flora application fails to adequately sanitize user-controlled data passed through HTTP headers before incorporating it into dynamically generated web pages. This allows attackers with low-level privileges to inject malicious script content that executes in the context of other users' browser sessions.

The attack can be performed remotely over the network without requiring user interaction, though the attacker needs some level of authentication to the system. The vulnerability enables attackers to compromise user confidentiality and integrity while potentially causing high availability impact to the affected system.

Root Cause

The root cause lies in insufficient input validation and output encoding for HTTP header values. When the application processes incoming HTTP requests, header values are directly reflected or stored and subsequently rendered in web pages without proper sanitization. This allows special characters and script tags to be interpreted as executable code rather than being treated as literal text.

Attack Vector

The attack is executed via network access by manipulating HTTP headers in requests to the vulnerable Flora web application. An authenticated attacker can craft malicious HTTP headers containing JavaScript payloads. When these headers are processed and reflected in the application's response or stored for later rendering, the injected script executes in the victim's browser context.

The exploitation flow typically involves:

1. The attacker authenticates to the Flora web application with minimal privileges
2. The attacker crafts HTTP requests with malicious script content embedded in header values
3. The vulnerable application processes the request without proper sanitization
4. The malicious payload is reflected or stored and later rendered in web pages
5. When other users access the affected pages, the JavaScript executes in their browser context

Detection Methods for CVE-2025-7760

Indicators of Compromise

• Unusual HTTP header values containing script tags (<script>) or JavaScript event handlers
• Encoded payloads in HTTP headers such as base64-encoded JavaScript or HTML entity encodings
• Log entries showing abnormal header sizes or suspicious character patterns in header fields

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block XSS patterns in HTTP headers
• Monitor application logs for requests containing script tags or JavaScript event handlers in header values
• Deploy browser-based security controls such as Content Security Policy (CSP) headers to detect script execution attempts

Monitoring Recommendations

• Enable detailed HTTP request logging to capture full header information for security analysis
• Configure alerting on anomalous header patterns including unusual encoding or excessive special characters
• Implement real-time monitoring for client-side JavaScript errors that may indicate XSS exploitation attempts

How to Mitigate CVE-2025-7760

Immediate Actions Required

• Implement strict input validation and output encoding for all HTTP header values processed by the application
• Deploy Content Security Policy (CSP) headers with strict script-src directives to mitigate XSS impact
• Review and audit all code paths where HTTP headers are reflected or stored for display
• Consider implementing HTTP-only and Secure flags on session cookies to limit exploitation impact

Patch Information

No vendor patch is currently available. The vendor (Ofisimo Web-Based Software Technologies) was contacted regarding this vulnerability but did not respond. Organizations should implement defensive measures until an official patch is released. For additional details, refer to the USOM Security Notification.

Workarounds

• Deploy a Web Application Firewall (WAF) with XSS-specific rulesets to filter malicious header content
• Implement server-side output encoding using context-appropriate encoding functions for all dynamic content
• Enable Content Security Policy headers with restrictive policies that prevent inline script execution
• Consider restricting access to the affected Flora application to trusted networks until a patch is available

# Example: Apache configuration for Content Security Policy header
# Add to your Apache configuration or .htaccess file
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; frame-ancestors 'none';"

# Example: Nginx configuration for Content Security Policy header
# Add to your server block configuration
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; frame-ancestors 'none';" always;
