CVE-2024-35315
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 Desktop Client of Mitel MiCollab through 9.7.1.110, and MiVoice Business Solution Virtual Instance (MiVB SVI) 1.0.0.25, could allow an authenticated attacker to conduct a privilege escalation attack due to improper file validation. A successful exploit could allow an attacker to run arbitrary code with elevated privileges.
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 vulnerability in Mitel MiCollab Desktop Client and MiVB SVI allows authenticated attackers to escalate privileges by exploiting improper file validation. An attacker can run arbitrary code with elevated system privileges, potentially compromising the entire affected system.

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 Mitel productCheck system for MiCollab Desktop Client or MiVoice Business Solution Virtual Instance (MiVB SVI) installation. Look for Mitel application directories, services, or the desktop client executable.Affected if Either MiCollab Desktop Client or MiVB SVI is installed
-
Determine MiCollab versionFor MiCollab Desktop Client, check the application's About section, or inspect the executable file properties for version information. Common locations: Program Files/Mitel or application installation directory.Affected if Version is 9.7.1.110 or earlier (any version up to and including 9.7.1.110)
-
Determine MiVB SVI versionFor MiVoice Business Solution Virtual Instance, check the service version through the management interface or system information. Look in the virtual appliance console or version documentation.Affected if Version is exactly 1.0.0.25
-
Verify authentication requirementConfirm whether user authentication is enabled and users have valid credentials to access the system. The vulnerability requires an authenticated attacker.Affected if The system allows user authentication and the file validation/import feature is accessible to authenticated users
A defender is affected if they have MiCollab Desktop Client version 9.7.1.110 or earlier, or MiVB SVI version 1.0.0.25, with authenticated user access enabled.

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 vendor-supplied patches to MiCollab version 9.7.1.110 or later and MiVB SVI version 1.0.0.25 or later to address the improper file validation vulnerability.
