CVE-2022-30993
📋 TL;DR
CVE-2022-30993 allows attackers to intercept sensitive information transmitted in cleartext between Acronis Cyber Protect components. This affects Acronis Cyber Protect 15 installations on Linux and Windows systems before build 29240, potentially exposing credentials, backup data, or configuration details.
💻 Affected Systems
- Acronis Cyber Protect 15
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers intercept administrative credentials, backup encryption keys, or sensitive customer data, leading to full system compromise, data theft, or ransomware deployment.
Likely Case
Attackers on the same network segment capture authentication tokens or configuration data, enabling unauthorized access to backup systems or privilege escalation.
If Mitigated
With proper network segmentation and encryption controls, impact is limited to internal network reconnaissance with no sensitive data exposure.
🎯 Exploit Status
Exploitation requires network access to sniff traffic between Acronis components. No authentication needed to intercept cleartext transmissions.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Build 29240 or later
Vendor Advisory: https://security-advisory.acronis.com/advisories/SEC-2441
Restart Required: Yes
Instructions:
1. Download Acronis Cyber Protect 15 build 29240 or later from official Acronis portal. 2. Backup current configuration. 3. Install update on all affected systems (agents and management servers). 4. Restart Acronis services. 5. Verify all components are communicating properly.
🔧 Temporary Workarounds
Network Segmentation
allIsolate Acronis Cyber Protect traffic to dedicated VLANs or network segments
VPN/Encryption Tunnel
allForce all Acronis component communication through encrypted VPN tunnels
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Acronis traffic from untrusted networks
- Deploy network monitoring and IDS/IPS to detect cleartext credential transmission
🔍 How to Verify
Check if Vulnerable:
Check Acronis Cyber Protect version: On Windows - Check Control Panel > Programs > Acronis Cyber Protect. On Linux - Run 'rpm -qa | grep acronis' or 'dpkg -l | grep acronis'. If version is earlier than build 29240, system is vulnerable.
Check Version:
Windows: Check installed programs list. Linux: 'acronis_cyber_protect_console --version' or check package manager.
Verify Fix Applied:
Verify version is 29240 or later and test component communication to ensure encrypted transmission is functioning.
📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts from unexpected IPs
- Unusual connection patterns between Acronis components
Network Indicators:
- Cleartext HTTP traffic between Acronis components on non-standard ports
- Unencrypted authentication strings in packet captures
SIEM Query:
source="acronis*" AND (event_type="authentication" OR event_type="connection") AND dest_ip!=expected_ip
