CVE-2018-15513
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 · uneditedLog viewer in totemomail 6.0.0 build 570 allows access to sessionIDs of high privileged users by leveraging access to a read-only auditor role.
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 confidenceThe log viewer component in totemomail 6.0.0 build 570 contains an information disclosure vulnerability where users with a read-only auditor role can access session IDs belonging to high-privileged users. This is a broken access control issue where the log viewer fails to properly restrict or filter sensitive session data based on user privilege levels.

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 Totemomail versionLocate the Totemomail installation directory and check the version information file or use the product's built-in version check command (typically available in admin interface or via command line tool)Affected if Installed version is exactly 6.0.0 build 570 or falls within the 6.0.0 release line
-
Verify log viewer component is accessibleNavigate to the log viewer feature in the Totemomail admin or user interface, typically found under monitoring, audit logs, or system logs sectionAffected if Log viewer component is present and accessible in the installation
-
Confirm auditor role is assignedCheck user role assignments in the Totemomail user management or authentication settings to verify if read-only auditor roles exist in the systemAffected if Read-only auditor role accounts are configured in the system
-
Test session ID visibility to auditorLog in with a read-only auditor account and navigate to the log viewer, then examine whether session IDs, authentication tokens, or session cookies for other users (particularly high-privileged administrators) are visible in the log outputAffected if Auditor role can view session IDs belonging to high-privileged users in the log viewer output
A user is affected if Totemomail version 6.0.0 is running with the log viewer accessible to read-only auditor accounts, and those auditors can see session IDs from higher-privileged users in the logs.

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 proper role-based access control (RBAC) in the log viewer to ensure auditors can only view logs relevant to their role, and redact or restrict access to session IDs and other sensitive authentication tokens from lower-privileged users.
