CVE-2016-5755
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 · uneditedNetIQ Access Manager 4.1 before 4.1.2 Hot Fix 1 and 4.2 before 4.2.2 was vulnerable to clickjacking attacks due to a missing SAMEORIGIN filter in the "high encryption" setting.
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 confidenceNetIQ Access Manager versions 4.1 before 4.1.2 Hot Fix 1 and 4.2 before 4.2.2 lacks the X-Frame-Options SAMEORIGIN HTTP response header in the 'high encryption' configuration. This allows remote attackers to embed the application's pages in iframes on malicious sites and perform clickjacking attacks by overlaying invisible or disguised UI elements to trick authenticated users into unknowingly triggering sensitive actions.

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 installed NetIQ Access Manager versionCheck the product version through the administration console or by inspecting the installer/ About section. Compare against the affected versions: 4.1 before 4.1.2 Hot Fix 1, or 4.2 before 4.2.2Affected if The installed version is 4.1.x below 4.1.2 (Hot Fix 1) or 4.2.x below 4.2.2
-
Determine if high encryption mode is enabledAccess the administration console and navigate to the encryption or SSL configuration settings. Look for a setting referred to as 'high encryption' or equivalent high-security encryption profileAffected if High encryption mode is enabled in the configuration
-
Inspect HTTP responses for X-Frame-Options headerUse a browser developer tool, curl, or a proxy to capture an HTTP response from the Access Manager login or protected resource pages. Examine the response headers for the presence of 'X-Frame-Options: SAMEORIGIN'Affected if The X-Frame-Options header is absent from HTTP responses when high encryption is enabled
-
Verify if the vulnerability applies to the specific deploymentConfirm that the affected endpoints (login page, admin console, or protected resources) are accessible over HTTPS and use the high encryption configurationAffected if The deployment uses high encryption AND serves responses without the X-Frame-Options header
A user is affected if they are running NetIQ Access Manager 4.1.x before 4.1.2 Hot Fix 1 or 4.2.x before 4.2.2 with high encryption mode enabled, and HTTP responses lack the X-Frame-Options: SAMEORIGIN header.
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 dataApply vendor-supplied hot fixes (4.1.2 Hot Fix 1 for version 4.1, or 4.2.2 for version 4.2) to add the X-Frame-Options: SAMEORIGIN header to all responses when the high encryption setting is enabled.
