CVE-2016-2303
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 · uneditedCRLF injection vulnerability in Ecava IntegraXor before 5.0 build 4522 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a crafted URL.
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 confidenceCRLF injection vulnerability in Ecava IntegraXor before version 5.0 build 4522 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via crafted URLs containing CRLF (\r\n) characters.

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 Ecava IntegraXor is installedCheck for the IntegraXor application in the system or look for its web server service (default port 8080). In Windows, check Program Files for Ecava folder or check Services for IntegraXor service.Affected if Ecava IntegraXor software is present on the system
-
Identify installed version numberOpen the IntegraXor application or check the About dialog in the web interface. Alternatively, check the version info of the IntegraXor executable file in the installation directory.Affected if Version displayed is 4.2.4502 or earlier, or if the version cannot be determined but the software is present and predates 2016
-
Verify web interface accessibilityAttempt to access the IntegraXor web server via browser at http://localhost:8080 or the configured port. The vulnerability affects the HTTP handling, so the web server must be running.Affected if Web interface is accessible and responding to HTTP requests
-
Confirm version is within affected rangeCompare the identified version against the affected range: versions <= 4.2.4502. Version 5.0 build 4522 and later are NOT affected.Affected if Installed version is 4.2.4502 or any version below 5.0 build 4522
A system is affected if Ecava IntegraXor version 4.2.4502 or earlier is installed and its web server is accessible, as the CRLF injection flaw exists in the HTTP response handling of those versions.

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 dataUpgrade to Ecava IntegraXor version 5.0 build 4522 or later. Implement input validation to reject URLs containing CRLF characters.
