CVE-2025-62329
📋 TL;DR
HCL DevOps Deploy/Launch has a race condition in HTTP session IP binding that may allow brief session reuse from a new IP address before invalidation. This could enable unauthorized access under specific timing conditions. Organizations using affected HCL DevOps products are impacted.
💻 Affected Systems
- HCL DevOps Deploy
- HCL Launch

⚠️ Risk & Real-World Impact
Worst Case
An attacker could hijack an active user session and gain unauthorized access to the DevOps platform, potentially compromising deployment pipelines and sensitive configuration data.
Likely Case
Limited session hijacking in controlled timing windows, potentially allowing brief unauthorized access if an attacker can precisely time requests during session transitions.
If Mitigated
Minimal impact with proper network segmentation, session timeouts, and monitoring in place.
🎯 Exploit Status
Exploitation requires precise timing (race condition) and existing session access. No public exploits known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific fixed versions
Vendor Advisory: https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0127332
Restart Required: Yes
Instructions:
1. Review HCL advisory KB0127332. 2. Identify affected version. 3. Apply vendor-provided patch. 4. Restart HCL DevOps services. 5. Verify fix implementation.
🔧 Temporary Workarounds
Reduce Session Timeout
allShorten HTTP session timeout values to minimize window for race condition exploitation
Configure in HCL DevOps application settings: Set session timeout to minimum practical value
Network Segmentation
allRestrict access to HCL DevOps interfaces to trusted networks only
Configure firewall rules to limit source IP addresses
🧯 If You Can't Patch
- Implement strict network access controls to limit which IPs can access HCL DevOps interfaces
- Enable detailed session logging and monitor for unusual session activity patterns
🔍 How to Verify
Check if Vulnerable:
Check HCL DevOps version against vendor advisory KB0127332. Review if session IP binding is enabled in configuration.Check Version:
Check HCL DevOps administration console or consult product documentation for version query commandVerify Fix Applied:
Verify patch installation via version check. Test session behavior with IP changes under controlled conditions.📡 Detection & Monitoring
Log Indicators:
- Rapid session creation/destruction from different IPs
- Session validation errors in application logs
- Multiple login attempts with session reuse patterns
Network Indicators:
- Unusual session persistence across IP changes
- HTTP requests with session cookies from unexpected source IPs
SIEM Query:
source="hcl_devops" AND (event_type="session_validation" OR event_type="authentication") AND src_ip_changed=true
