CVE-2004-0315
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 · uneditedBuffer overflow in Avirt Voice 4.0 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long GET request on port 1080.
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 · high confidenceBuffer overflow vulnerability in Avirt Voice 4.0's built-in web server listening on port 1080. Remote attackers can send specially crafted long GET requests to trigger the overflow, causing denial of service (service crash) and potentially executing arbitrary code with elevated privileges.

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.
-
Confirm Avirt Voice 4.0 installationCheck system for presence of Avirt Voice version 4.0 by reviewing installed programs list, program files directory, or product-specific service entriesAffected if Avirt Voice 4.0 is installed on the system
-
Verify web server is running on port 1080Run command to check if any process is listening on port 1080 (for example, netstat -ano | findstr :1080 or equivalent port scanning tool)Affected if A service is actively listening on TCP port 1080
-
Determine if the web server is the Avirt Voice serviceIdentify the process bound to port 1080 and confirm it is associated with Avirt Voice (compare process ID from step 2 against tasklist or process explorer)Affected if The process listening on port 1080 is Avirt Voice or its web server component
-
Assess network exposure of port 1080Check firewall rules or network accessibility to determine if port 1080 accepts external connections (for example, firewall rules, router port forwarding, or scanning the exposed IP address on port 1080)Affected if Port 1080 is accessible from untrusted network locations such as the internet or shared networks
You are affected if Avirt Voice 4.0 is installed with its built-in web server enabled and listening on port 1080, and that port is exposed to network locations where attackers could send malicious GET requests.

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 dataIf the product is still in use, apply any available vendor patches; otherwise, restrict network access to port 1080 via firewall or disable the service entirely. Consider migration to supported alternatives given the software's age.
