CVE-2019-7177
📋 TL;DR
CVE-2019-7177 is a code injection vulnerability in Pexip Infinity that allows authenticated administrators to execute arbitrary code on nodes. This affects organizations using Pexip Infinity video conferencing solutions before version 20.1. The vulnerability requires admin-level access to exploit.
💻 Affected Systems
- Pexip Infinity
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of Pexip Infinity nodes allowing attackers to execute arbitrary code, potentially leading to data theft, service disruption, or lateral movement within the network.
Likely Case
Privileged attackers with admin access could execute malicious code to disrupt video conferencing services, steal sensitive meeting data, or maintain persistence in the environment.
If Mitigated
With proper access controls and network segmentation, impact is limited to the Pexip Infinity environment itself, though service disruption remains possible.
🎯 Exploit Status
Exploitation requires admin credentials. The vulnerability is in the admin interface allowing code injection.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 20.1 and later
Vendor Advisory: https://docs.pexip.com/admin/security_bulletins.htm
Restart Required: Yes
Instructions:
1. Backup current configuration. 2. Upgrade Pexip Infinity to version 20.1 or later. 3. Restart services as required by the upgrade process. 4. Verify functionality post-upgrade.
🔧 Temporary Workarounds
Restrict Admin Access
allLimit administrative access to only trusted personnel and implement strong authentication controls.
Network Segmentation
allIsolate Pexip Infinity management interfaces from general network access.
🧯 If You Can't Patch
- Implement strict access controls and monitoring for admin accounts
- Segment Pexip Infinity management interfaces and implement network-level restrictions
🔍 How to Verify
Check if Vulnerable:
Check Pexip Infinity version via admin interface or SSH. Versions before 20.1 are vulnerable.Check Version:
pexip --versionVerify Fix Applied:
Verify version is 20.1 or later via admin interface or SSH command 'pexip --version'.📡 Detection & Monitoring
Log Indicators:
- Unusual admin activity patterns
- Unexpected code execution attempts in system logs
- Multiple failed admin login attempts
Network Indicators:
- Unusual outbound connections from Pexip nodes
- Suspicious traffic to/from management interfaces
