CVE-2023-27791
📋 TL;DR
This vulnerability in IXP Data Easy Install 6.6.148840 allows remote attackers to escalate privileges due to insecure pseudo-random number generation (PRNG). Attackers can potentially gain elevated system access by predicting or manipulating random values used in authentication or authorization processes. Organizations using this specific version of IXP Data Easy Install are affected.

📦 What is this software?
Easyinstall by Ixpdata
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise where an attacker gains administrative privileges, accesses sensitive data, installs persistent malware, or pivots to other systems in the network.
Likely Case
Privilege escalation allowing unauthorized access to restricted functionality or data within the Easy Install application, potentially leading to data theft or further exploitation.
If Mitigated
Limited impact with proper network segmentation, least privilege access controls, and monitoring that detects anomalous privilege escalation attempts.
🎯 Exploit Status
Exploitation requires understanding of the PRNG implementation and likely some initial access to the system.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check with IXP Data for an updated version or patch. 2. If available, download and apply the patch following vendor instructions. 3. Verify the fix by testing privilege escalation attempts.
🔧 Temporary Workarounds
Network Segmentation
allIsolate the affected system from critical networks and limit access to trusted IPs only.
Access Control Hardening
allImplement strict least privilege principles and monitor for unusual privilege escalation attempts.
🧯 If You Can't Patch
- Implement network-level controls to restrict access to the vulnerable system only to necessary users and systems.
- Deploy enhanced monitoring and alerting for privilege escalation patterns and unusual authentication events.
🔍 How to Verify
Check if Vulnerable:
Check the installed version of IXP Data Easy Install; if it is version 6.6.148840, the system is vulnerable.
Check Version:
Check application documentation or system logs for version information; specific command depends on installation method.
Verify Fix Applied:
After applying any vendor patch, verify the version has changed from 6.6.148840 and test for privilege escalation vulnerabilities.
