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
A vulnerability in the MiCollab Client server component of Mitel MiCollab through 9.5.0.101 could allow an authenticated attacker to conduct a Server-Side Request Forgery (SSRF) attack due to insufficient restriction of URL parameters. A successful exploit could allow an attacker to leverage connections and permissions available to the host server.

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

This is a Server-Side Request Forgery (SSRF) vulnerability in the MiCollab Client server component of Mitel MiCollab (versions through 9.5.0.101). The vulnerability stems from insufficient restriction of URL parameters, allowing an authenticated attacker to manipulate the server into making arbitrary HTTP requests to internal or external resources. This enables the attacker to leverage the server's network position and trusted relationships to access sensitive services or internal systems.

MitigationImplement strict allowlist-based validation for URL parameters and restrict outbound network connections from the MiCollab server. Apply any vendor patches when available and consider network segmentation to limit the server's ability to reach internal resources.

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 Mitel MiCollab installation
    Locate MiCollab installation directories or check system services for MiCollab components. Common paths include /opt/mitel/micollab or C:\Program Files\Mitel\MiCollab on Windows. Use 'ls' or directory listing commands to find MiCollab-related directories.
    Affected if Mitel MiCollab software is found on the system
  2. Determine MiCollab version
    Check the installed version by reviewing version files, About dialogs, or running version lookup commands specific to MiCollab. Common methods include examining README files, version.info files, or using vendor-provided version inquiry tools within the MiCollab installation directory.
    Affected if The installed version is 9.5.0.101 or lower (any version through 9.5.0.101)
  3. Verify MiCollab Client server component status
    Identify if the MiCollab Client server component is running and enabled. Check Windows Services, systemd services, or the MiCollab administration console to determine if the Client server component is active. This component handles URL parameters and is the attack surface for SSRF.
    Affected if The MiCollab Client server component is running and accessible on the network
  4. Check authentication configuration
    Review MiCollab user authentication settings and determine if unauthenticated access is possible to the Client server component endpoints. Examine authentication configuration files or admin console settings to understand the authentication requirements for URL-based requests.
    Affected if An attacker can obtain valid credentials or the component accepts authenticated requests from external sources

The environment is affected if Mitel MiCollab version 9.5.0.101 or lower is installed with the MiCollab Client server component enabled and accessible to an authenticated attacker.

From vendor data
Upgrade available Upgrade to a release after 9.5.0.101
Interim mitigation

Implement strict allowlist-based validation for URL parameters and restrict outbound network connections from the MiCollab server. Apply any vendor patches when available and consider network segmentation to limit the server's ability to reach internal resources.
