CVE-2018-1664
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 7.1.0.0 - 7.1.0.23, 7.2.0.0 - 7.2.0.21, 7.5.0.0 - 7.5.0.16, 7.5.1.0 - 7.5.1.15, 7.5.2.0 - 7.5.2.15, and 7.6.0.0 - 7.6.0.8 as well as IBM DataPower Gateway CD 7.7.0.0 - 7.7.1.2 echoing of AMP management interface authorization headers exposes login credentials in browser cache. IBM X-Force ID: 144890.
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 confidenceThe AMP (Advanced Management Panel) management interface of IBM DataPower Gateway echoes authorization headers containing plaintext login credentials in HTTP responses. These credentials are cached by the browser, allowing attackers with access to the browser cache (via malware, shared workstations, or cache exploitation) to recover valid credentials.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 DataPower Gateway versionAccess the DataPower Gateway administrative interface or check the system version through the CLI (show version) or management API. Compare the installed version against the affected ranges: 7.1.0.0-7.1.0.23, 7.2.0.0-7.2.0.21, 7.5.0.0-7.5.0.16, 7.5.1.0-7.5.1.15, 7.5.2.0-7.5.2.15, 7.6.0.0-7.6.0.8, or 7.7.0.0-7.7.1.2.Affected if The installed version falls within any of the listed affected ranges.
-
Verify the AMP management interface is in useConfirm that the Advanced Management Panel (AMP) interface is enabled and accessible. This is typically accessible on port 9090 or through the WebGUI management interface.Affected if The AMP interface is enabled and exposed for management access.
-
Capture and inspect HTTP responses from the AMP interfaceUse a web proxy or browser developer tools to capture HTTP responses when authenticating to the AMP interface. Examine response bodies and headers for the presence of the Authorization header or Basic authentication credentials in plaintext.Affected if HTTP responses contain the Authorization header or plaintext credentials in the response body or headers.
-
Inspect browser cache for cached credentialsExamine the browser cache or proxy cache for stored responses from the AMP interface. Look for cached pages or resources that may contain authorization credentials.Affected if Cached responses contain Base64-encoded or plaintext credentials from authentication attempts.
A user is affected if their DataPower Gateway version is within the affected ranges AND the AMP management interface is enabled AND HTTP responses echo authorization credentials or those credentials are found in browser cache.

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-supplied patches or upgrade to a fixed version outside the affected ranges. Additionally, configure strict cache-control headers to prevent caching of sensitive responses and consider implementing additional access controls on the management interface.
