CVE-2018-1668
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 · uneditedIBM DataPower Gateway 7.5.0.0 through 7.5.0.19, 7.5.1.0 through 7.5.1.18, 7.5.2.0 through 7.5.2.18, and 7.6.0.0 through 7.6.0.11 appliances allows "null" logins which could give read access to IPMI data to obtain sensitive information. IBM X-Force ID: 144894.
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 confidenceIBM DataPower Gateway allows 'null' logins (authentication bypass using empty credentials), which provides unauthorized read access to IPMI (Intelligent Platform Management Interface) data containing sensitive system information. An unauthenticated remote attacker could exploit this to obtain confidential platform management data.

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 IBM DataPower Gateway installationCheck for IBM DataPower Gateway processes, services, or web interface on the system. Look for typical default ports (9090 for web management, 22 for SSH) or inspect installed software packages.Affected if IBM DataPower Gateway is present on the network or system
-
Determine the installed DataPower Gateway versionAccess the web management interface and navigate to the Status section, or run 'show version' via CLI. Compare the version number against the affected ranges: 7.5.0.0-7.5.0.19, 7.5.1.0-7.5.1.18, 7.5.2.0-7.5.2.18, or 7.6.0.0-7.6.0.11.Affected if The installed version falls within any of the listed vulnerable ranges
-
Verify IPMI interface exposureCheck if the IPMI (Intelligent Platform Management Interface) service is accessible on the network. Common IPMI port is 623/UDP. Use tools like 'nmap -p 623 -sU <target>' or check firewall rules for inbound UDP port 623.Affected if IPMI interface is reachable from an untrusted network or the internet
-
Test for null login vulnerabilityAttempt to access IPMI data or the DataPower management interface using empty or null credentials. For IPMI, try 'ipmitool -I lanplus -H <target> -u '' -P '' command' or similar to authenticate with empty username and password.Affected if Authentication succeeds with empty credentials, granting unauthorized access to IPMI data
The environment is affected if IBM DataPower Gateway is running a version within 7.5.0.0-7.5.0.19, 7.5.1.0-7.5.1.18, 7.5.2.0-7.5.2.18, or 7.6.0.0-7.6.0.11 AND the IPMI interface is network-accessible, allowing authentication bypass with empty credentials.

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 dataUpdate IBM DataPower Gateway to a version beyond 7.5.0.19, 7.5.1.18, 7.5.2.18, or 7.6.0.11. Additionally, network-segment the management interfaces and restrict IPMI access to prevent exposure.
