CVE-2024-37856
📋 TL;DR
This Cross-Site Scripting (XSS) vulnerability in Lost and Found Information System 1.0 allows attackers to inject malicious scripts into user profile fields (first, middle, last name). When other users view these profiles, the scripts execute in their browsers, potentially enabling privilege escalation. Organizations using this specific software version are affected.
💻 Affected Systems
- Lost and Found Information System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could steal administrator session cookies, take over admin accounts, and gain full control of the system to modify data, create new users, or deploy additional malware.
Likely Case
Attackers steal user session cookies to impersonate legitimate users, access sensitive lost-and-found data, or perform unauthorized actions within the system.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized, preventing execution and limiting impact to data integrity issues.
🎯 Exploit Status
Exploitation requires user-level access to modify profile fields. Public proof-of-concept exists on Packet Storm Security.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: http://lost.com
Restart Required: No
Instructions:
1. Check vendor website for updates. 2. If patch available, download and apply following vendor instructions. 3. Test functionality after patching.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation to reject or sanitize HTML/JavaScript in name fields.
N/A - Requires code changes
Output Encoding
allEncode user-controlled data before rendering in HTML context to prevent script execution.
N/A - Requires code changes
🧯 If You Can't Patch
- Disable user profile editing functionality if not essential
- Implement web application firewall (WAF) rules to block XSS payloads in name parameters
🔍 How to Verify
Check if Vulnerable:
Test by entering <script>alert('XSS')</script> in first/middle/last name fields and check if script executes when viewing profile.Check Version:
Check application version in admin panel or about pageVerify Fix Applied:
Repeat the test with sanitized input - script should not execute and should be displayed as plain text.📡 Detection & Monitoring
Log Indicators:
- Unusual length or special characters in name field submissions
- Multiple profile updates from single user
Network Indicators:
- HTTP requests with script tags in POST parameters to profile update endpoints
SIEM Query:
source="web_logs" AND (uri_path="/profile/update" OR uri_path="/user/edit") AND (param_name="first_name" OR param_name="last_name" OR param_name="middle_name") AND param_value MATCHES "<script>"🔗 References
