CVE-2022-24562
📋 TL;DR
CVE-2022-24562 allows unauthenticated attackers to send GET/POST requests to Airserv in IOBit IOTransfer, granting them full file-system read/write access with admin privileges. This can lead to data theft and remote code execution. All users running the vulnerable version of IOTransfer are affected.
💻 Affected Systems
- IOBit IOTransfer
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise: attacker gains full administrative control, steals all data, installs persistent malware, and uses the system as a pivot point for further attacks.
Likely Case
Data exfiltration and remote code execution leading to ransomware deployment, credential theft, or system takeover.
If Mitigated
Limited impact if network segmentation prevents external access and endpoint protection blocks malicious payloads.
🎯 Exploit Status
Public exploit code and detailed write-ups exist, making this easily weaponizable by attackers with minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Update to latest version (check vendor site)
Vendor Advisory: http://iobit.com
Restart Required: Yes
Instructions:
1. Open IOTransfer. 2. Click 'Menu' → 'Check for Updates'. 3. Follow prompts to install latest version. 4. Restart computer.
🔧 Temporary Workarounds
Block Airserv Port
windowsBlock network access to the Airserv component using firewall rules
netsh advfirewall firewall add rule name="Block IOTransfer Airserv" dir=in action=block protocol=TCP localport=8080
Uninstall IOTransfer
windowsRemove vulnerable software entirely
Control Panel → Programs → Uninstall IOTransfer
🧯 If You Can't Patch
- Segment network to isolate systems running IOTransfer from internet and critical internal networks
- Implement strict endpoint detection and response (EDR) rules to monitor for suspicious file system access patterns
🔍 How to Verify
Check if Vulnerable:
Check if IOTransfer version is 4.3.1.1561 or earlier and Airserv service is running on port 8080Check Version:
Open IOTransfer → Menu → AboutVerify Fix Applied:
Confirm IOTransfer version is updated beyond 4.3.1.1561 and Airserv service is no longer accessible📡 Detection & Monitoring
Log Indicators:
- Unusual file access patterns from IOTransfer process
- Network connections to port 8080 from unexpected sources
Network Indicators:
- HTTP GET/POST requests to port 8080 with file system paths
- Unusual outbound traffic following IOTransfer exploitation
SIEM Query:
source_port=8080 AND (http_method=GET OR http_method=POST) AND url_path CONTAINS "/airserv/"🔗 References
