Likely Case
Session hijacking, credential theft, or unauthorized actions performed in users' names via crafted phishing links.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers blocking script execution.
🎯 Exploit Status
Exploit requires user interaction (clicking a malicious link); proof-of-concept is publicly available in GitHub gists.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v6.11 or later
Vendor Advisory: https://webhelp.evisions.com/releaseguides/maps/default.htm#6.11/6.11%20Release%20Notes.htm?TocPath=MAPS%25206.11%2520Release%2520Guide%257C_____3
Restart Required: Yes
Instructions:
1. Backup current MAPS installation. 2. Download MAPS v6.11 or later from Evisions. 3. Install the update following vendor instructions. 4. Restart MAPS services.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize user inputs in the /mw/ endpoint.
Configure web server (e.g., Apache mod_security) or application filters to block script tags and malicious payloads.
Content Security Policy (CSP)
allSet CSP headers to restrict script execution sources, mitigating XSS impact.
Add header: Content-Security-Policy: default-src 'self'; script-src 'self'
🧯 If You Can't Patch
- Implement strict input validation and output encoding for all user inputs in the /mw/ endpoint.
- Deploy a Web Application Firewall (WAF) with XSS protection rules to block malicious requests.
🔍 How to Verify
Check if Vulnerable:
Test by injecting a simple script payload (e.g., <script>alert('XSS')</script>) into parameters of the /mw/ endpoint and check if it executes in browser.Check Version:
Check MAPS version via admin interface or configuration files; refer to vendor documentation for exact command.Verify Fix Applied:
After patching, repeat the vulnerability test; script execution should be blocked or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual requests to /mw/ endpoint with script tags or encoded payloads in query parameters.
- Multiple failed login attempts or session anomalies following suspicious /mw/ accesses.
Network Indicators:
- HTTP requests containing <script>, javascript:, or encoded characters in /mw/ URL parameters.
- Traffic spikes to /mw/ endpoint from unusual sources.
SIEM Query:
source="web_logs" AND url="/mw/" AND (query CONTAINS "<script>" OR query CONTAINS "javascript:")
