CVE-2007-5789
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Grandstream HT-488 0.1 allows remote attackers to cause a denial of service (device crash) via a flood of fragmented packets to port 5060.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Grandstream HT-488 VoIP adapter has a denial of service vulnerability where processing a flood of fragmented packets on port 5060 (the standard SIP signaling port) causes the device to crash and become unresponsive.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelAccess the device web interface or check the device label/sticker to confirm it is a Grandstream HT-488 VoIP adapterAffected if The device is NOT a Grandstream HT-488 model
-
Check the firmware versionLog into the device administrative interface and navigate to the status or system information page to view the firmware versionAffected if The firmware version is 0.1
-
Verify SIP service is enabledCheck the device configuration for SIP settings and confirm port 5060 is configured as the listening port for SIP signalingAffected if Port 5060 is not configured or SIP is disabled entirely
-
Assess network exposurePerform a port scan or check network configuration to determine if port 5060 is exposed to untrusted networks (such as the public internet)Affected if Port 5060 is directly accessible from untrusted networks without firewall protection
A user is affected if they have a Grandstream HT-488 with firmware version 0.1 that has SIP port 5060 enabled and accessible on the network, making it vulnerable to the fragmented packet DoS attack.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSince this is a legacy device from 2007 likely no longer receiving firmware updates, network-level protections such as rate limiting, firewall rules filtering malformed/fragmented packets at the network edge, or complete device replacement with a supported VoIP gateway should be implemented.
