CVE-2018-9026
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 session fixation vulnerability in CA Privileged Access Manager 2.x allows remote attackers to hijack user sessions with a specially crafted request.
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 confidenceSession fixation vulnerability in CA Privileged Access Manager 2.x allows remote attackers to hijack authenticated user sessions by using a specially crafted request to set or predict the session identifier before the victim authenticates, then reusing that same session ID after authentication to gain unauthorized access.

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 product and versionCheck the application version through the management console, about page, or command line utility (such as 'capamversion' or similar administrative tool). Look for version information in the product's web interface under Administration or System Information.Affected if The installed version is Broadcom Privileged Access Manager (formerly CA PAM) version 2.0.0 or higher but lower than 3.0.0.
-
Confirm the product is the vulnerable componentVerify that the identified product is the Privileged Access Manager server component and not a different CA/Broadcom product. The vulnerability affects the core PAM server handling authentication sessions.Affected if The product is the CA/Broadcom Privileged Access Manager server in the affected version range.
-
Inspect session management configurationAccess the administrative console and navigate to Session Management or Security Settings. Look for configuration options related to session ID handling, specifically whether session IDs are regenerated after successful authentication.Affected if Session ID regeneration after authentication is disabled, not configured, or set to reuse pre-authentication session identifiers.
-
Review authentication workflow for session handlingExamine the authentication logs or use a test account to perform a login while monitoring session cookies or session identifiers. Observe whether a new session ID is issued after successful authentication compared to before authentication.Affected if The session identifier remains the same or is predictable between the pre-authentication and post-authentication states.
You are affected if Broadcom Privileged Access Manager version 2.0.0 through 2.x is installed and session IDs are not regenerated after authentication, allowing session fixation attacks.

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 data3.0.0
Implement proper session ID regeneration upon successful authentication and invalidate any pre-authentication session identifiers. Additionally, configure the application to use cryptographically random, unpredictable session IDs and enforce session expiration policies.
