CVE-2024-52881
📋 TL;DR
AudioCodes OVOC versions before 8.4.582 use a hard-coded cryptographic key, allowing attackers to decrypt sensitive data like passwords from topology files. This affects organizations using AudioCodes One Voice Operations Center for VoIP management. Attackers with access to topology files can compromise administrative credentials.
💻 Affected Systems
- AudioCodes One Voice Operations Center (OVOC)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise through credential theft leading to unauthorized administrative access, data exfiltration, and potential lateral movement within the network.
Likely Case
Attackers extract and decrypt passwords from accessible topology files, gaining administrative access to OVOC and potentially connected VoIP systems.
If Mitigated
Limited impact if topology files are properly secured with strict access controls and network segmentation.
🎯 Exploit Status
Exploitation requires access to topology files and knowledge of the hard-coded key. No public exploit code available at disclosure.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.4.582
Vendor Advisory: https://www.audiocodes.com/solutions-products/products/management-products-solutions/one-voice-operations-center
Restart Required: No
Instructions:
1. Download OVOC version 8.4.582 or later from AudioCodes support portal. 2. Backup current configuration. 3. Install the update following AudioCodes upgrade documentation. 4. Verify successful installation.
🔧 Temporary Workarounds
Restrict topology file access
allImplement strict file system permissions to limit access to topology files containing encrypted credentials.
Network segmentation
allIsolate OVOC management interface from untrusted networks and implement strict firewall rules.
🧯 If You Can't Patch
- Implement strict access controls to topology files and monitor for unauthorized access attempts.
- Rotate all credentials stored in OVOC and implement multi-factor authentication where possible.
🔍 How to Verify
Check if Vulnerable:
Check OVOC version in web interface or via CLI. Versions below 8.4.582 are vulnerable.Check Version:
Check web interface or use OVOC CLI command: show versionVerify Fix Applied:
Confirm OVOC version is 8.4.582 or higher and verify topology files no longer use hard-coded encryption.📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to topology files
- Multiple failed authentication attempts followed by successful login
Network Indicators:
- Unusual network traffic from OVOC management interface
- Suspicious file transfers involving topology files
