CVE-2014-9564
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 IBM Flex System EN6131 40Gb Ethernet and IB6131 40Gb Infiniband Switch firmware before 3.4.1110 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks and resulting web cache poisoning or cross-site scripting (XSS) attacks, or obtain sensitive information via multiple unspecified parameters.
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 IBM Flex System EN6131 40Gb Ethernet and IB6131 40Gb Infiniband Switch firmware before version 3.4.1110 allows remote attackers to inject arbitrary HTTP headers via unsanitized parameters, enabling HTTP response splitting attacks. This can lead to web cache poisoning, cross-site scripting (XSS) attacks, or disclosure of sensitive information.

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 switch modelAccess the switch CLI or management interface and retrieve the hardware model identifier. For CLI, use commands like 'show version' or 'show system'. Look for model numbers EN6131 or IB6131.Affected if The device is confirmed to be an IBM Flex System EN6131 or IB6131 switch
-
Check the current firmware versionExecute 'show version' or 'show firmware' in the switch CLI to display the installed firmware version. Record the full version number string.Affected if The firmware version is below 3.4.1110 or cannot be determined (all versions before the fix are affected)
-
Verify the web management interface is enabledCheck the switch configuration for HTTP or HTTPS web interface settings. In CLI, look for commands like 'show http' or 'show running-config | include http'. Confirm whether the web-based management is active.Affected if The web management interface (HTTP/HTTPS) is enabled and accessible
-
Assess network accessibility of the management interfaceDetermine if the management interface is reachable from untrusted networks. Check VLAN configuration, ACLs, and management IP accessibility. Attempt to access the web interface URL or port 80/443 from a non-management network segment.Affected if The web management interface is exposed to networks beyond the trusted management segment
You are affected if your device is an IBM EN6131 or IB6131 running firmware version below 3.4.1110 and the HTTP web management interface is enabled and accessible.
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 dataUpgrade IBM Flex System EN6131 and IB6131 switch firmware to version 3.4.1110 or later to remediate this vulnerability. If immediate patching is not possible, restrict network access to the management interface and implement WAF rules to detect CRLF injection attempts.
