CVE-2017-11196
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 · uneditedPulse Connect Secure 8.3R1 has CSRF in logout.cgi. The logout function of the admin panel is not protected by any CSRF tokens, thus allowing an attacker to logout a user by making them visit a malicious web page.
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 confidencePulse Connect Secure 8.3R1 contains a Cross-Site Request Forgery vulnerability in the logout.cgi function of the admin panel. The logout mechanism lacks CSRF token protection, enabling attackers to force authenticated users to log out by tricking them into visiting a malicious webpage that makes a forged request to the logout endpoint.

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 Pulse Connect Secure installationAccess the admin web interface or check the system for Pulse Connect Secure. The admin panel is typically accessible at https://[hostname]/admin or look for the Pulse Secure login page.Affected if The system is running Pulse Connect Secure software
-
Determine the installed versionCheck the version displayed on the admin login page, in system diagnostics, or via command line using 'get system info' or similar command on the appliance.Affected if The version is exactly 8.3r1.0 (8.3R1)
-
Verify the logout endpoint existsAttempt to access or verify the presence of /logout.cgi on the admin interface. This is typically found at https://[hostname]/admin/logout.cgiAffected if The logout.cgi endpoint is accessible and responds to requests
-
Confirm admin panel is exposedVerify the admin panel is network-accessible (check listening services, firewall rules, or access the web interface). The vulnerability requires the admin to be authenticated.Affected if The admin panel with login functionality is accessible to users who can be tricked into visiting malicious pages
You are affected if you are running Pulse Connect Secure version 8.3r1.0 and the admin panel is accessible, since the logout.cgi function in that specific version lacks CSRF token protection.

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 dataImplement CSRF token validation on the logout function, or configure the session cookies with the SameSite=Strict attribute to prevent cross-origin logout requests.
