CVE-2025-0158
📋 TL;DR
This vulnerability in IBM EntireX 11.1 allows a local user to cause a denial of service through an unhandled error condition. The issue stems from improper fault isolation mechanisms that can be triggered by a local attacker. Only systems running IBM EntireX 11.1 with local user access are affected.
💻 Affected Systems
- IBM EntireX
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete service disruption of IBM EntireX components, potentially affecting dependent applications and business processes.
Likely Case
Temporary service interruption requiring manual restart of affected EntireX services.
If Mitigated
Minimal impact with proper access controls and monitoring in place to detect and respond to service disruptions.
🎯 Exploit Status
Exploitation requires local access but appears straightforward based on the CWE-248 description of unhandled exceptions.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply fix as specified in IBM advisory
Vendor Advisory: https://www.ibm.com/support/pages/node/7182693
Restart Required: Yes
Instructions:
1. Review IBM advisory at the provided URL. 2. Download and apply the appropriate fix for your platform. 3. Restart EntireX services. 4. Verify the fix is applied successfully.
🔧 Temporary Workarounds
Restrict Local Access
allLimit local user access to systems running IBM EntireX to only authorized administrators.
# Use OS-specific access controls to restrict user accounts
# Example for Linux: chmod 750 /path/to/entirex
# Example for Windows: Configure local security policies
Implement Service Monitoring
allSet up monitoring and alerting for EntireX service disruptions to enable rapid response.
# Configure monitoring tools to check EntireX service status
# Example: systemctl status entirex
# Set up alerts for service failures
🧯 If You Can't Patch
- Implement strict least-privilege access controls for local users on affected systems
- Deploy additional monitoring and automated restart mechanisms for EntireX services
🔍 How to Verify
Check if Vulnerable:
Check if IBM EntireX version 11.1 is installed and review system logs for unhandled error messages related to EntireX services.Check Version:
# Check EntireX version through its administration interface or installed package info
# Example for Linux: rpm -qa | grep entirex
# Example for Windows: Check Programs and Features or use PowerShell: Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like '*EntireX*'}Verify Fix Applied:
Verify the fix is applied by checking the version/patches installed and monitoring for recurrence of service disruptions from unhandled errors.📡 Detection & Monitoring
