6.5 MEDIUM

📋 TL;DR

CVE-2024-39967 is an insecure permissions vulnerability in Aginode GigaSwitch v5 that allows attackers to access sensitive information via SCP commands. This affects organizations using vulnerable versions of Aginode GigaSwitch v5 network switching software.

💻 Affected Systems

Products:
  • Aginode GigaSwitch
Versions: v5 (specific subversions not specified in available information)
Operating Systems: Linux-based network appliance OS
Default Config Vulnerable: ⚠️ Yes
Notes: Affects systems where SCP service is enabled with insecure file permissions on sensitive directories.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could exfiltrate sensitive configuration files, credentials, or network topology data, potentially leading to full network compromise.

🟠

Likely Case

Unauthorized access to configuration files containing network settings, passwords, or other sensitive operational data.

🟢

If Mitigated

Limited impact with proper network segmentation and access controls preventing external SCP access.

🌐 Internet-Facing: HIGH if SCP service is exposed to internet without proper authentication and authorization controls.
🏢 Internal Only: MEDIUM as internal attackers could exploit this to gain unauthorized access to sensitive information.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires SCP access but leverages insecure file permissions rather than authentication bypass.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Not specified

Vendor Advisory: Not available

Restart Required: No

Instructions:

1. Check vendor website for security updates. 2. Apply any available patches. 3. Verify file permissions are corrected.

🔧 Temporary Workarounds

Restrict SCP Access

linux

Limit SCP access to trusted IP addresses only using firewall rules.

iptables -A INPUT -p tcp --dport 22 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j DROP

Fix File Permissions

linux

Set proper permissions on sensitive directories to prevent unauthorized SCP access.

chmod 700 /path/to/sensitive/directories
chown root:root /path/to/sensitive/directories

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate GigaSwitch systems from untrusted networks.
  • Disable SCP service if not required for operations and use alternative secure file transfer methods.

🔍 How to Verify

Check if Vulnerable:

Check if SCP service is accessible and test if sensitive files can be accessed via SCP without proper authorization.

Check Version:

Check device web interface or CLI for version information (specific command varies by deployment).

Verify Fix Applied:

Verify that SCP access to sensitive directories is properly restricted and file permissions are corrected.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SCP connections from unauthorized IP addresses
  • Failed SCP authentication attempts followed by successful transfers

Network Indicators:

  • SCP traffic to GigaSwitch systems from unexpected sources
  • Large data transfers via SCP protocol

SIEM Query:

source_port=22 AND (protocol="SCP" OR application="SCP") AND destination_ip=GIGASWITCH_IP AND bytes_transferred>1000000
