CVE-2019-5314
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 · uneditedSome web components in the ArubaOS software are vulnerable to HTTP Response splitting (CRLF injection) and Reflected XSS. An attacker would be able to accomplish this by sending certain URL parameters that would trigger this vulnerability.
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 confidenceArubaOS web components fail to properly sanitize URL parameters, allowing attackers to inject CRLF sequences into HTTP headers (HTTP Response splitting) and embed malicious JavaScript into reflected responses (Reflected XSS). This occurs when user-supplied input in URL parameters is not validated or encoded before being returned in HTTP responses.

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 ArubaOS device and confirm web interfaceLog into the Aruba device via CLI or access the web management interface. In CLI, use 'show version' to display system information. Via web, the login page typically displays the ArubaOS version.Affected if Device is not running ArubaOS or web interface is not accessible
-
Retrieve the exact ArubaOS versionIn CLI, run 'show version' and note the 'OS Version' field. In the web UI, the version is usually shown on the login page or under Maintenance > System > Platform.Affected if Unable to determine the installed ArubaOS version number
-
Compare version against affected rangesCompare your installed version to: < 6.4.4.20, >= 6.5.4.0 AND < 6.5.4.11, >= 6.5.4.12 AND < 8.2.1.0, >= 8.2.1.1 AND < 8.3.0.0. Note that versions 6.5.4.11 and 8.2.1.0 are NOT listed as affected.Affected if Installed version falls within any of the affected version ranges listed above
-
Confirm web components are enabledVerify the ArubaOS web interface (HTTPS/HTTP) is enabled and accessible. Check via CLI with 'show web-server' or by attempting to access the device's IP via a web browser.Affected if Web interface is disabled, as the vulnerability requires the web components to be active
You are affected if your ArubaOS version falls within the listed ranges AND the web interface is enabled, allowing CRLF injection in URL parameters leading to HTTP response splitting or reflected XSS.

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 data6.4.4.206.5.4.118.2.1.0
Apply the vendor patch from Aruba for ArubaOS. If patching is delayed, implement input validation and output encoding for all URL parameters in web component code to prevent CRLF injection and XSS.
