CVE-2024-55925
📋 TL;DR
This vulnerability allows attackers to bypass API host restrictions in Xerox Workplace Suite by forging Host headers. Attackers can access sensitive API endpoints that should be restricted to specific hosts. Organizations using vulnerable versions of Xerox Workplace Suite are affected.
💻 Affected Systems
- Xerox Workplace Suite
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of sensitive API endpoints, unauthorized data access, and potential privilege escalation within the Workplace Suite environment.
Likely Case
Unauthorized access to restricted API functions, potential data exposure, and manipulation of Workplace Suite configurations.
If Mitigated
Limited impact with proper network segmentation, API gateway controls, and strict host validation in place.
🎯 Exploit Status
Requires ability to send crafted HTTP requests to the vulnerable API endpoints.
🛠️ Fix & Mitigation
✅ Official Fix

Vendor Advisory: https://securitydocs.business.xerox.com/wp-content/uploads/2025/01/Xerox-Security-Bulletin-XRX25-002-for-Xerox%C2%AE-WorkplaceSuite%C2%AE.pdf
Restart Required: No
Instructions:
1. Download and apply the latest Xerox Workplace Suite updates from official sources. 2. Verify the update addresses CVE-2024-55925. 3. Test API functionality post-update.
🔧 Temporary Workarounds
Implement API Gateway with Strict Host Validation
allDeploy an API gateway or reverse proxy that enforces strict Host header validation before requests reach the vulnerable server.
Network Segmentation and Access Controls
allRestrict network access to Workplace Suite API endpoints using firewalls, allowing only trusted hosts.
🧯 If You Can't Patch
- Isolate the vulnerable system in a restricted network segment with no internet exposure.
- Implement strict network access controls (ACLs) to limit which hosts can communicate with the API endpoints.
🔍 How to Verify
Check if Vulnerable:
Test by sending HTTP requests to restricted API endpoints with forged Host headers; if access is granted, the system is vulnerable.Check Version:
Check the Xerox Workplace Suite version via the application interface or configuration files (specific command varies by deployment).Verify Fix Applied:
After patching, repeat the test with forged Host headers; access should be denied.📡 Detection & Monitoring
Log Indicators:
- Unusual Host header values in HTTP logs
- Access attempts from unexpected IPs to restricted API endpoints
Network Indicators:
- HTTP requests with manipulated Host headers to API endpoints
- Traffic patterns indicating API access from unauthorized sources
SIEM Query:
