CVE-2024-55550

Mitel MiCollab

Mitel MiCollab contains a path traversal vulnerability that could allow an authenticated attacker with administrative privileges to read local files within the system due to insufficient input sanitization. This vulnerability can be chained with CVE-2024-41713, which allows an unauthenticated, remote attacker to read arbitrary files on the server.

Exploitation status

  • CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
  • It is known to have been used in ransomware campaigns.
  • US federal civilian agencies are required to remediate it by 2025-01-28. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.

Required action

Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
