CVE-2025-52656
📋 TL;DR
CVE-2025-52656 is a mass assignment vulnerability in HCL MyXalytics 6.6 that allows attackers to modify sensitive application fields without proper authorization. This affects organizations using HCL MyXalytics 6.6 where user input can be bound to internal objects without validation.
💻 Affected Systems
- HCL MyXalytics
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could modify critical configuration settings, escalate privileges, manipulate data integrity, or compromise the entire application.
Likely Case
Unauthorized modification of user profiles, configuration settings, or application data leading to data manipulation or limited privilege escalation.
If Mitigated
With proper input validation and access controls, the vulnerability would be prevented, allowing only authorized modifications to permitted fields.
🎯 Exploit Status
Exploitation requires understanding of the application's object structure and typically requires authenticated access to the application.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched version
Vendor Advisory: https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0124411
Restart Required: Yes
Instructions:
1. Review the HCL advisory for patch availability. 2. Download and apply the official patch from HCL. 3. Restart the MyXalytics application. 4. Verify the fix is applied.
🔧 Temporary Workarounds
Implement Input Validation
allAdd server-side validation to ensure only permitted fields can be modified through mass assignment.
Use Allow/Deny Lists
allImplement explicit allow or deny lists for mass assignment parameters to restrict which fields can be modified.
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all user-controlled parameters
- Apply network segmentation and restrict access to the MyXalytics application to authorized users only
🔍 How to Verify
Check if Vulnerable:
Check if running HCL MyXalytics version 6.6 and review application logs for unexpected parameter modifications.Check Version:
Check MyXalytics administration console or configuration files for version informationVerify Fix Applied:
Verify the application version has been updated beyond 6.6 and test that mass assignment attempts with unauthorized fields are rejected.📡 Detection & Monitoring
Log Indicators:
- Unusual parameter modifications in application logs
- Multiple field updates in single requests
