CVE-2023-27791

8.1 HIGH

📋 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.

💻 Affected Systems

Products:
  • IXP Data Easy Install
Versions: 6.6.148840
Operating Systems: Not specified in CVE
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the specific build 6.6.148840; other versions may also be affected but this is the confirmed version.

📦 What is this software?

⚠️ 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.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

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

all

Isolate the affected system from critical networks and limit access to trusted IPs only.

Access Control Hardening

all

Implement 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.

📡 Detection & Monitoring

Log Indicators:

  • Unusual privilege escalation events
  • Failed authentication attempts followed by successful elevated access
  • Log entries indicating PRNG-related errors or anomalies

Network Indicators:

  • Unexpected network connections from the Easy Install system to sensitive internal resources
  • Traffic patterns suggesting lateral movement post-exploitation

SIEM Query:

source="easy_install_logs" AND (event_type="privilege_escalation" OR user_change="elevated")
