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 · unedited
Log 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 confidence

The 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.

MitigationImplement 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.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Totemomail version
    Locate 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
  2. Verify log viewer component is accessible
    Navigate to the log viewer feature in the Totemomail admin or user interface, typically found under monitoring, audit logs, or system logs section
    Affected if Log viewer component is present and accessible in the installation
  3. Confirm auditor role is assigned
    Check user role assignments in the Totemomail user management or authentication settings to verify if read-only auditor roles exist in the system
    Affected if Read-only auditor role accounts are configured in the system
  4. Test session ID visibility to auditor
    Log 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 output
    Affected 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.

Mitigation

Implement 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.
