CVE-2024-25730
📋 TL;DR
This vulnerability allows attackers to easily guess the default pre-shared keys (PSKs) on Hitron CODA-4582 and CODA-4589 cable modem/router devices due to insufficient entropy in key generation. Attackers who gain access to the PSK can potentially take over the device's administrative functions. All users of affected Hitron devices with default configurations are vulnerable.
💻 Affected Systems
- Hitron CODA-4582
- Hitron CODA-4589
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device takeover allowing attacker to reconfigure network settings, intercept traffic, install malware, or use the device as part of a botnet.
Likely Case
Unauthorized access to device administration leading to network configuration changes, DNS hijacking, or credential theft from connected devices.
If Mitigated
Limited impact if custom PSKs are used and strong authentication controls are implemented.
🎯 Exploit Status
Attack requires network access to the device but can be automated due to small key space (~1M possibilities).
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Users must implement workarounds.
🔧 Temporary Workarounds
Change Default PSK
allReplace the default pre-shared key with a strong, randomly generated key
Access device admin interface > Wireless Settings > Security > Change PSK to random 20+ character string
Disable Remote Administration
allTurn off remote management features to prevent external attacks
Access device admin interface > Management > Remote Management > Disable
🧯 If You Can't Patch
- Isolate affected devices in separate network segment with strict firewall rules
- Implement network monitoring for suspicious authentication attempts to device admin interface
🔍 How to Verify
Check if Vulnerable:
Check if device uses default PSK by accessing admin interface and reviewing wireless security settings. Default PSKs follow pattern: 5-digit hex value + 'Hitron'.Check Version:
Access device admin interface > Status > Device Information to check firmware versionVerify Fix Applied:
Verify PSK has been changed to a strong, random value not following the vulnerable pattern.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts to admin interface
- Successful admin login from unexpected IP addresses
Network Indicators:
- Unusual traffic patterns from modem/router
- DNS configuration changes
- New admin sessions from external IPs
