CVE-2024-41713: Mitel MiCollab

Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

Yes, if you run Mitel MiCollab. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-01-07, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-01-28; treat that as the outer limit, not the target. CISA also lists it as known to be used in ransomware campaigns.
EPSS 97.2%, percentile 99.9: FIRST’s model estimates a 97.2% chance of exploitation activity in the next 30 days, higher than 99.9% of all scored CVEs (very high). EPSS is a probability, not a verdict.
Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.

What it is

A vulnerability in the NuPoint Unified Messaging (NPM) component of Mitel MiCollab through 9.8 SP1 FP2 (9.8.1.201) could allow an unauthenticated attacker to conduct a path traversal attack, due to insufficient input validation. A successful exploit could allow unauthorized access, enabling the attacker to view, corrupt, or delete users' data and system configurations.

CISA’s summary

Mitel MiCollab contains a path traversal vulnerability that could allow an attacker to gain unauthorized and unauthenticated access. This vulnerability can be chained with CVE-2024-55550, which allows an unauthenticated, remote attacker to read arbitrary files on the server.
