CVE-2023-50350
📋 TL;DR
HCL DRYiCE MyXalytics uses a broken cryptographic algorithm for encryption, potentially allowing attackers to decrypt sensitive information. This affects organizations using vulnerable versions of the software, exposing encrypted data to unauthorized access.
💻 Affected Systems
- HCL DRYiCE MyXalytics
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers decrypt all encrypted sensitive data, leading to data breaches, compliance violations, and reputational damage.
Likely Case
Attackers decrypt specific encrypted data, such as credentials or personal information, for exploitation or sale.
If Mitigated
With proper controls like network segmentation and monitoring, impact is limited to isolated systems with minimal data exposure.
🎯 Exploit Status
Exploitation requires knowledge of the broken algorithm and access to encrypted data; no public exploits confirmed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to vendor advisory for specific patched versions.
Vendor Advisory: https://support.hcltechsw.com/csm?id=kb_article&sysparm_article=KB0109608
Restart Required: Yes
Instructions:
1. Review vendor advisory for patch details. 2. Download and apply the patch from HCL support. 3. Restart the MyXalytics service to implement changes.
🔧 Temporary Workarounds
Disable vulnerable encryption features
allTemporarily disable or reconfigure encryption to use secure algorithms if supported.
Specific commands not provided; consult product documentation for configuration changes.
🧯 If You Can't Patch
- Isolate affected systems from untrusted networks to limit access.
- Implement strict access controls and monitoring for unusual decryption activities.
🔍 How to Verify
Check if Vulnerable:
Check the software version against the vendor advisory; if using a vulnerable version, assume vulnerability.Check Version:
Consult HCL DRYiCE MyXalytics documentation for version check commands; typically via admin interface or configuration files.Verify Fix Applied:
Verify the installed version matches the patched version listed in the vendor advisory.📡 Detection & Monitoring
Log Indicators:
- Unusual decryption attempts or errors in encryption logs.
Network Indicators:
- Suspicious traffic patterns to encryption endpoints.
