CVE-2025-48780
📋 TL;DR
A critical deserialization vulnerability in Soar Cloud HRD Human Resource Management System allows remote attackers to execute arbitrary system commands by sending crafted serialized objects to the download file function. This affects all organizations using Soar Cloud HRD versions through 7.3.2025.0408, potentially compromising entire HR systems and underlying infrastructure.
💻 Affected Systems
- Soar Cloud HRD Human Resource Management System
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise leading to data exfiltration, ransomware deployment, lateral movement across the network, and persistent backdoor installation.
Likely Case
Attacker gains initial foothold, escalates privileges, accesses sensitive HR data (employee records, payroll information), and potentially moves to other systems.
If Mitigated
Attack contained to isolated HR system segment with minimal data exposure if proper network segmentation and least privilege controls are implemented.
🎯 Exploit Status
The advisory suggests remote exploitation is possible without authentication, making this highly attractive to attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Contact Soar Cloud vendor for patch information. 2. Monitor vendor communications for security updates. 3. Apply patch immediately when available.
🔧 Temporary Workarounds
Network Isolation
allRestrict network access to the HRD system to only trusted internal networks
Configure firewall rules to block external access to HRD system ports
Input Validation Filter
allImplement WAF or application filter to block serialized object patterns
Add WAF rule to block content containing serialized object signatures
🧯 If You Can't Patch
- Implement strict network segmentation to isolate HRD system from critical infrastructure
- Deploy application control/whitelisting to prevent execution of unauthorized processes
🔍 How to Verify
Check if Vulnerable:
Check application version against affected range. If running version 7.3.2025.0408 or earlier, assume vulnerable.Check Version:
Check application interface or configuration files for version informationVerify Fix Applied:
Verify installation of vendor-provided patch for versions after 7.3.2025.0408📡 Detection & Monitoring
