CVE-2015-2122
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 REST layer on HP SDN VAN Controller devices 2.5 and earlier allows remote attackers to cause a denial of service via network traffic to the REST port.
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 confidenceHP SDN VAN Controller devices version 2.5 and earlier contain a denial of service vulnerability in the REST layer. Remote attackers can send malicious traffic to the REST port, causing the service to become unavailable. The vulnerability stems from improper handling of network requests to the REST API, likely due to insufficient input validation, lack of rate limiting, or improper resource management.

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 HP SDN VAN Controller is installedCheck for HP SDN VAN Controller software on the system. On Linux, look for process 'sdnvan' or check /opt for HP SDN directories. On the appliance interface, navigate to the About or System Information page.Affected if The software is not present on the system.
-
Determine the installed versionRun 'sdnvan-controller -v' or check the version through the management interface under About/Version information. Alternatively, check the RPM package: rpm -qa | grep sdnvanAffected if The version is 2.5 or earlier.
-
Verify the REST service is runningCheck if the REST API service is active. Look for Java processes listening on REST ports (typically 8443 or 8080) using 'netstat -tlnp | grep -E "(8080|8443)"' or check the SDN VAN Controller service status.Affected if The REST service is running and exposed.
-
Check network exposure of REST portIdentify the REST port from configuration (typically 8443 for HTTPS or 8080 for HTTP) and verify accessibility using 'nmap -p <port> <controller-ip>' or by reviewing firewall rules with 'iptables -L' or 'firewall-cmd --list-all'.Affected if The REST port is accessible from untrusted networks.
The environment is affected if HP SDN VAN Controller version 2.5 or earlier is installed and the REST API service is running and accessible from the network.

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 dataApply vendor-provided patches or upgrade HP SDN VAN Controller to a version later than 2.5. If no patch is available, implement network-level rate limiting and access controls to restrict REST port exposure to authorized sources only.
