CVE-2024-41713
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.
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.
