CVE-2023-28003
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 CWE-613: Insufficient Session Expiration vulnerability exists that could allow an attacker to maintain unauthorized access over a hijacked session in PME after the legitimate user has signed out of their account.
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 confidenceA CWE-613 Insufficient Session Expiration vulnerability exists in PME where server-side session invalidation does not occur properly upon user logout. This allows an attacker who has hijacked a session to maintain unauthorized access even after the legitimate user has signed out, because the session token remains valid in the server's session store.

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 product and versionLocate the Ecostruxure Power Monitoring Expert installation and determine the exact version number. Common locations include C:\Program Files\Schneider Electric\Power Monitoring Expert or /opt/Schneider Electric/Power Monitoring Expert. Check version information in the application properties, about dialog, or installation directory.Affected if The installed version is Ecostruxure Power Monitoring Expert 2022 or any earlier version.
-
Verify session management configurationExamine the web application configuration files for session management settings. Look for session timeout configurations, session tracking methods, and session cookie settings in the application's web.xml or equivalent configuration.Affected if Session timeout is set to an excessively long duration, or session tracking is configured without proper server-side session invalidation on logout.
-
Test session token validity after logoutAuthenticate to the PME web interface, capture the session cookie/token, perform logout, then attempt to use the original session token to access protected resources.Affected if The original session token remains valid and grants access after logout has been completed.
-
Review session store implementationInspect the server-side session storage mechanism to determine whether session data is being destroyed or marked as invalid when a user initiates logout.Affected if The session store retains active session records after logout, allowing session reuse.
You are affected if Ecostruxure Power Monitoring Expert version 2022 or earlier is installed and sessions remain usable after logout.

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.
dbcve · scopedImplement proper server-side session invalidation by destroying session data on logout and enforcing session timeouts to ensure sessions cannot be reused after expiration or logout.
