CVE-2016-5758
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 · uneditedA cross site request forgery protection mechanism in NetIQ Access Manager 4.1 before 4.1.2 Hot Fix 1 and 4.2 before 4.2.2 could be circumvented by repeated uploads causing a high load.
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 · moderate confidenceNetIQ Access Manager versions 4.1 before 4.1.2 Hot Fix 1 and 4.2 before 4.2.2 contain a CSRF protection mechanism that can be circumvented. Attackers bypass the anti-CSRF tokens by repeatedly triggering file uploads to induce high server load, which degrades or bypasses the CSRF validation controls.

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 installed NetIQ Access Manager versionAccess the administration console or check system information to determine the exact version of NetIQ Access Manager installed. Look for version details in the product about section or versioninfo file.Affected if Version is 4.1 before 4.1.2 Hot Fix 1 OR version is 4.2 before 4.2.2
-
Confirm file upload capability is accessibleVerify whether the file upload feature within the Access Manager administration interface or user portal is exposed and functional. Check if the upload endpoint accepts requests.Affected if File upload functionality is enabled and accessible to users or administrators
-
Check for CSRF token enforcement in formsInspect the HTML source of forms within the Access Manager admin console and user portal to confirm anti-CSRF tokens are present in form submissions.Affected if CSRF tokens are missing from sensitive forms or token validation appears inconsistent
-
Monitor server performance under file upload loadObserve server response times and resource utilization when multiple file upload requests are submitted in succession. Check if CSRF validation fails or degrades under this load.Affected if CSRF protection weakens or fails when the system is under load from repeated file uploads
You are affected if your NetIQ Access Manager version falls within 4.1 before 4.1.2 Hot Fix 1 or 4.2 before 4.2.2 AND the file upload feature is accessible, as the CSRF bypass occurs under upload-induced server load.

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 hotfix 4.1.2 Hot Fix 1 or 4.2.2 (depending on branch) to restore effective CSRF protection. Test authentication and session handling after applying the patch.
