Critical RCE Vulnerability Discovered in Siklu EtherHaul EH-8010 Devices (CVE Pending)

Critical Remote Command Execution Flaw in Siklu EtherHaul EH-8010

Security researchers have identified a severe unauthenticated remote command execution (RCE) vulnerability in Siklu's EtherHaul EH-8010 series wireless radios, potentially allowing attackers to gain full control of affected devices. The exploit (EDB-ID: 52466) was published on Exploit Database without an assigned CVE identifier at the time of reporting.

Technical Details

The vulnerability exists in the web management interface of EtherHaul EH-8010 devices, which are high-capacity wireless radios used in enterprise and carrier-grade networks. The flaw stems from improper input validation in the device's web interface, enabling attackers to execute arbitrary commands with root privileges through specially crafted HTTP requests.

Key technical characteristics:

• Attack Vector: Remote (network-accessible)
• Authentication: Unauthenticated (no credentials required)
• Privilege Level: Root access
• Exploit Availability: Public proof-of-concept (Exploit-DB 52466)
• Affected Versions: Specific firmware versions not yet disclosed

Impact Analysis

The RCE vulnerability presents significant risks for organizations utilizing Siklu EtherHaul EH-8010 devices in their network infrastructure:

1. Complete System Compromise: Attackers can execute commands with root privileges, enabling full control over the wireless radio device
2. Network Propagation: Compromised devices could serve as pivot points for lateral movement within enterprise networks
3. Data Interception: Ability to intercept or manipulate wireless traffic passing through affected devices
4. Persistence Mechanisms: Potential for installing backdoors or malware on vulnerable devices

Recommendations

Security teams should take immediate action to mitigate risks:

1. Temporary Mitigation: Restrict access to the web management interface via firewall rules, allowing only trusted IP addresses
2. Monitoring: Implement enhanced logging and monitoring for suspicious activity targeting EtherHaul devices
3. Vendor Communication: Contact Siklu support for official patches and firmware updates
4. Network Segmentation: Isolate EtherHaul devices in dedicated network segments with strict access controls
5. Exploit Detection: Deploy IDS/IPS signatures to detect exploitation attempts using the public proof-of-concept

Siklu has not yet issued an official security advisory or patch for this vulnerability. Organizations should treat this as an active threat given the public availability of exploit code.
