CVE-2017-12225
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 vulnerability in the web functionality of the Cisco Prime LAN Management Solution could allow an authenticated, remote attacker to hijack another user's administrative session, aka a Session Fixation Vulnerability. The vulnerability is due to the reuse of a preauthentication session token as part of the postauthentication session. An attacker could exploit this vulnerability by obtaining the presession token ID. An exploit could allow an attacker to hijack an existing user's session. Known Affected Releases 4.2(5). Cisco Bug IDs: CSCvf58392.
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 confidenceThis is a session fixation vulnerability in Cisco Prime LAN Management Solution where the pre-authentication session token is reused as the post-authentication session token. An attacker who obtains the pre-session token ID can continue using it after the user authenticates, effectively hijacking the user's administrative session.

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.
-
Confirm Cisco Prime LMS installationIdentify if Cisco Prime LAN Management Solution is deployed in your environment. This is typically installed on Linux or Solaris systems and accessed via web interface on ports 8080 or 8443.Affected if You cannot confirm the product is installed - you are not affected by this CVE.
-
Determine installed versionAccess the LMS web interface and navigate to the About or Version page, or check via CLI using 'show version' or inspect the installed RPM/package: 'rpm -q cisco-prime-lms' or check /opt/CSCOlms/etc/lms.ini for version string.Affected if The installed version is NOT exactly 4.2(5) - you are not affected by this specific CVE.
-
Verify session token behavior (optional confirmation)If running version 4.2(5), capture a session token before authentication, authenticate with valid credentials, then check if the post-authentication session ID matches the pre-authentication token. Compare cookie or session identifier before and after login.Affected if The session token remains identical before and after authentication - you are confirmed affected by CVE-2017-12225.
You are affected by CVE-2017-12225 ONLY if your installed Cisco Prime LAN Management Solution is exactly version 4.2(5) and the pre-authentication session token is reused as the post-authentication session token.

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 the Cisco fix for bug CSCvf58392 or upgrade to a patched release. As a compensating control, ensure users close all sessions after authentication and avoid accessing LMS from shared/untrusted systems.
