CVE-2020-11798Public exploitNetwork attack vector

Arbitrary file read via crafted URL traversal

Published Jun 10, 2020 · Updated Aug 4, 2024

Path traversal in Mitel MiCollab AWV before 8.1.2.4 and 9.0 through 9.1.2 allows remote attackers to read restricted server files. The web conference component processes crafted URL paths without sufficient access validation, permitting resolution into restricted directories. No authentication or user interaction is required, and successful exploitation exposes file contents without reported write access.
