CVE-2024-45102
📋 TL;DR
This privilege escalation vulnerability allows authenticated Lenovo XClarity Administrator (LXCA) users to gain elevated permissions on connected XClarity Controller (XCC) instances when LXCA is configured as a Single Sign-On provider. It affects organizations using Lenovo's infrastructure management software with SSO enabled between LXCA and XCC. Attackers need valid LXCA credentials to exploit this vulnerability.

⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains administrative control over XCC instances, potentially compromising managed servers, accessing sensitive data, and executing arbitrary commands on infrastructure hardware.
Likely Case
Malicious insider or compromised account escalates privileges to modify XCC configurations, disrupt server management, or access restricted management interfaces.
If Mitigated
Attackers remain limited to their original LXCA permissions without gaining unauthorized XCC access, maintaining proper access segregation.
🎯 Exploit Status
Exploitation requires valid LXCA credentials and SSO configuration. The vulnerability is in the SSO token validation mechanism.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: LXCA 5.5.2
Vendor Advisory: https://support.lenovo.com/us/en/product_security/LEN-154748
Restart Required: Yes
Instructions:
1. Download LXCA 5.5.2 from Lenovo support site. 2. Backup current LXCA configuration. 3. Apply the update through LXCA web interface or CLI. 4. Restart LXCA services. 5. Verify SSO functionality with XCC instances.
🔧 Temporary Workarounds
Disable SSO for XCC
allTemporarily disable Single Sign-On between LXCA and XCC instances, requiring separate authentication for XCC access.
Navigate to LXCA web interface > Settings > Authentication > SSO Configuration > Disable XCC SSO
Restrict LXCA User Permissions
allApply principle of least privilege to LXCA users, limiting who can access XCC management functions.
Use LXCA role-based access control to create minimal privilege roles for standard users
🧯 If You Can't Patch
- Implement network segmentation to isolate LXCA and XCC management interfaces from general user networks
- Enable detailed logging and monitoring of all LXCA authentication and XCC access attempts
🔍 How to Verify
Check if Vulnerable:
Check LXCA version via web interface (Settings > About) or CLI command 'lxca version'. If version is below 5.5.2 and SSO is configured for XCC, system is vulnerable.Check Version:
lxca versionVerify Fix Applied:
After updating to 5.5.2, verify version shows 5.5.2 and test SSO functionality with XCC instances to ensure proper authentication flow.📡 Detection & Monitoring
Log Indicators:
- Unexpected privilege escalation events in LXCA logs
- Multiple failed SSO attempts followed by successful XCC access
- XCC access from non-admin LXCA users
Network Indicators:
- Unusual XCC management traffic patterns
- SSO token requests from unexpected sources
