CVE-2007-6759

9.8 CRITICAL

📋 TL;DR

This vulnerability allows remote attackers to bypass authentication on Dataprobe iBootBar power distribution units by setting a specific cookie value (DCRABBIT). This enables unauthorized power cycling of connected devices, affecting organizations using these devices for remote power management.

💻 Affected Systems

Products:
  • Dataprobe iBootBar
Versions: Firmware released 2007-09-20 and possibly later versions
Operating Systems: Embedded firmware
Default Config Vulnerable: ⚠️ Yes
Notes: All default configurations are vulnerable as the authentication bypass is inherent to the firmware.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could remotely power off critical infrastructure equipment, causing service outages, data loss, or physical damage to connected devices.

🟠

Likely Case

Unauthorized power cycling of servers, network equipment, or other connected devices leading to service disruption and potential data corruption.

🟢

If Mitigated

Limited impact if devices are behind firewalls with strict network segmentation and access controls.

🌐 Internet-Facing: HIGH - The vulnerability allows unauthenticated remote exploitation if devices are exposed to the internet.
🏢 Internal Only: MEDIUM - Internal attackers or compromised internal systems could exploit this to disrupt operations.

🎯 Exploit Status

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

Exploitation requires only setting a specific cookie value, making it trivial for attackers with network access.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown specific version - check with Dataprobe for updated firmware

Vendor Advisory: Not available in provided references

Restart Required: Yes

Instructions:

1. Contact Dataprobe for updated firmware. 2. Backup current configuration. 3. Upload new firmware via web interface. 4. Reboot device. 5. Verify authentication works correctly.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate iBootBar devices on separate VLANs with strict firewall rules

Access Control Lists

all

Implement IP-based restrictions to limit access to management interface

🧯 If You Can't Patch

  • Disconnect iBootBar from internet and place behind strict firewall with only trusted IP access
  • Implement physical security controls to prevent unauthorized access to power connections

🔍 How to Verify

Check if Vulnerable:

Attempt to access iBootBar web interface with DCRABBIT cookie set to any value. If access is granted without authentication, device is vulnerable.

Check Version:

Check firmware version via iBootBar web interface under System Information

Verify Fix Applied:

Test that authentication is required for all management functions and DCRABBIT cookie no longer bypasses authentication.

📡 Detection & Monitoring

Log Indicators:

  • Unauthenticated access to power control functions
  • Multiple failed login attempts followed by successful access

Network Indicators:

  • HTTP requests containing DCRABBIT cookie to iBootBar management interface
  • Unexpected power cycling commands

SIEM Query:

source="iBootBar" AND (cookie="DCRABBIT" OR action="power" AND NOT auth_success="true")
