CVE-2025-41101
📋 TL;DR
This CVE describes an HTML injection vulnerability in Fairsketch's RISE CRM Framework that allows attackers to inject malicious HTML code through the 'title' parameter in POST requests to '/projects/save'. This affects all users of RISE CRM Framework v3.8.1 who have projects functionality enabled, potentially allowing attackers to deface pages or conduct phishing attacks.
💻 Affected Systems
- Fairsketch RISE CRM Framework
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject malicious scripts that steal session cookies, redirect users to phishing sites, or deface the CRM interface, potentially leading to account compromise and data theft.
Likely Case
Most attackers would use this for defacement or phishing by injecting HTML that displays misleading content or redirects users to malicious sites.
If Mitigated
With proper input validation and output encoding, the injected HTML would be displayed as plain text rather than executed as code.
🎯 Exploit Status
Exploitation requires sending a POST request with malicious HTML in the 'title' parameter. Authentication status is unclear from available information.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-fairsketchs-rise-crm-framework
Restart Required: No
Instructions:
1. Monitor vendor for patch release. 2. Apply patch when available. 3. Test in development environment before production deployment.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize HTML tags in the 'title' parameter
Implement input sanitization in the save_project() function to strip or encode HTML tags
WAF Rule
allConfigure web application firewall to block HTML injection attempts in POST parameters
Configure WAF to detect and block patterns like <script>, <iframe>, javascript: in POST parameters
🧯 If You Can't Patch
- Disable or restrict access to the projects module if not essential for business operations
- Implement strict Content Security Policy (CSP) headers to mitigate impact of successful injections
🔍 How to Verify
Check if Vulnerable:
Test by sending a POST request to '/projects/save' with HTML tags in the 'title' parameter and check if they render in the applicationCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
After applying fixes, test that HTML tags in the 'title' parameter are properly encoded and displayed as plain text📡 Detection & Monitoring
Log Indicators:
- POST requests to '/projects/save' with HTML tags in parameters
- Unusual length or content in 'title' parameter values
Network Indicators:
- HTTP POST requests containing HTML tags in body parameters
- Unusual spikes in requests to projects endpoint
SIEM Query:
source="web_server" AND method="POST" AND uri="/projects/save" AND (body CONTAINS "<script>" OR body CONTAINS "<iframe>" OR body CONTAINS "javascript:")
